Verified Patient Reviews
This was the best doctor’s visit I’ve ever had!
Dr. Gruenspan and his staff were very helpful during my visit. The examination was started very quickly after my arrival at the office and they were very thorough with the consultation. My visit with Dr. Gruenspan and his office was excellent.
This doctor is amazing. Took his time to ask me questions regarding previous diagnosis. Very clear with his consultation. Office staff was awesome! Lissette has the hands of an angel when it comes to taking out blood.
He is awesome!!! I was at first concerned bc he is an older doctor, but he adresses every single concern. He examines me down to my toes. Balance was off he had me stand on one leg, hands shaking he had me hold a piece of paper, he checked my pressure sittinf standing and laying. He took his time, so the little 10 minute waitni had was nothing. Oh the staff is awesome too
It was a very good visit. The staff is friendly. My vitals were taken right away and I only waited five minutes to see the doctor. Dr. Gruenspan was attentive. He listened to me and answered my questions. Even though I was his last appointment I never felt that he was in a hurry.
Took my appointment on short notice through Zocdoc, everyone at the office was super friendly, helpful, and knowledgeable. Dr. Gruenspan was excellent and thorough. Was quick to call in a prescription for me. Best experience I have had at a doctors office by far!
He was very patient and answered each and every question that I had. Everyone who works in the office is incredibly nice and sweet. I didn’t have to wait long. Everything was just perfect.
The doctor Very kind and infomative. The front desk staff was super nice
An excellent academic physician.
Dr Gruenspan is great! I don't know if I've ever had a Doctor so patient and willing to spend the time to make you feel like you're his only patient!
A very good person and an excellent academic physician.
Dr. G. is compassionate with a great sense of humor. He doesn't hustle patients in and out and I'm always impressed at how much time he takes to help calm one's anxieties. I like him so much I made him my PCP.
Dr. Gruenspan's office is GREAT! Danielle at the front desk is a sweetheart. She is very accommodating, helpful and caring. Lisette (I believe this was her name who took blood) was gentile and talked me through procedure. Dr. Gruenspan is very patient when getting to know you. He is thorough in his evaluation and listens to your concerns. He also referred me to an amazing radiology place (Lennox Hill) so his affiliates are just as great. I am lucky to have found this Dr. He and his staff are angels! I would refer this office to anyone and everyone! Stellar!
I was so impressed with the staff from the moment we walked in to the office. Very friendly. Dr. Gruenspan listen to all my husbands concerns. Never felt rushed through the examination. We are in good hands with Dr. Gruenspan.
Dr. Gruenspan is an amazing endocrinologist, internal specialist and primary care physician. He is personal, thorough, caring, methodical and very interested in treating the medical issue/concern. I've been going to him for several years and he is always there for me. His staff is also a wonderful group of people---equally helpful, great with vitals, blood draws, always friendly and interested in my well being, etc. I feel beyond blessed to have found Dr. Gruenspan and his staff.
Everyone in the office is very nice! The last time I saw Dr. Gruenspan was 4 years ago and he acted as if he remembered my entire health history (even though I'm sure he had just scanned my file quickly before seeing me). He genuinely listened to me and made me feel optimistic in finding out and fixing what is going on. Highly recommend.
Dr. Gruenspan was very kind and knowledgable. He took his time with questions/exam, and I didn't feel rushed at all. Danielle (at reception) was very friendly and helpful- this is a hard thing to find in a lot of doc offices, and it makes a big difference in someone's visit.
Everyone was hospitable, courteous and caring. The staff made me feel comfortable and a part of a new family from the time of entry. Doc was gentle, knowledgeable and supportive . I highly recommend this doctor!
Dr. Gruenspan was very attentive and thorough. He is an excellent doctor and I would certainly recommend him. The staff was great as well.
Dr Gruenspan was great, he was very professional and educated. I would definitely recommend him to others.
I was pleased to have Dr. Gruenspan treat me. He is polite and thorough, and was able to address most, if not all, of the concerns that I had regarding my condition.
This is the best Dr.'s office :-)! I was a little late but unlike some offices the staff was very friendly and didn't make me wait. The doctor takes his time and you are NOT rushed along.
The front desk staff is friendly and professional. The nurse is amazing. She has taken my blood 4 or 5 times and Never hurt me! I mean at all . Dr. Gruenspan is very knowledgeable. He listens and takes the time to explain everything to you..
Excellent doctor! Dr. Gruenspan addressed my issues and explained my medical situation and resulting treatment in a clear way to my satisfaction. My experience with Dr. Gruenspan and his staff was entirely pleasant and I am very happy with the outcome of my appointment. He is very professional and extremely knowledgeable. I will certainly go back for further appointments.
GREAT!!! My experience with Dr. Gruenspan and his staff was beyond amazing!! Dr. Gruenspan spent a good amount of time with me which really surprised me; not a lot of doctors spend a good amount of time with you. He took his time to listen to me and gave me such great advice. He did not rush me which makes me feel like he was really listening. He was very calm and had a great smile! Not to mention VERY smart. I knew I was in good hands. They take the blood in the office(which is a plus) and the nurse was very gentle and caring....didn't feel a thing. The young lady at the front desk was great; from check in to check out she had a smile and made me feel so comfortable. Making him my PCP. To sum up my experience with Dr. Gruenspan.... IT WAS GREAT!! I DEFINITELY RECOMMEND HIM!
Wonderful Visit. Dr. Gruenspan really took the time to go over all my issues and answer all of my questions, The staff was wonderful as well, Highly recommended.
The doctor and staff were terrific as usual. Dr Gruenspan was detailed and thorough as usual. I feel very well taken care of.
He was horribly creepy, unkempt, and downright bizarre. His office was dirty and disorganized. There were four urine samples that had yet to be collected sitting in the bathroom. Absolutely VILE!
Just an excellent Doctor - took the time to address every question and give a thorough exam. Would recommend him 100%
Very,very thorough.Listens very well,magnificent hands.
I have been seeing Dr. G for years now. He has always been prompt, courteous and professional. His staff is lovely and very welcoming.

Dr. Gruenspan was courteous, answered all my questions, and seemed very knowledgeable about his work.
The staff is super friendly and helpful.
It was really great. Dr. Gruenspan asked a lot of questions to fully understand my issues. He is very considerate and patient. The in house lab test saves me a lot of time.
First rate personnel in the office from the take-in desk to the nurses and medical assistants. Of course, the physician is excellent. Highly recommended.
Doctor was good but it was really difficult to follow up with the office on labs
He was very professional and polite. He listened to my concerns. I would recommend him!
Still the best!
Excellent. One of the best doctors in NYC. Very thorough and diligent.
Dr. Gruenspan was kind, calm, and took the time to listen to me and my concerns. Great doctor and I'm so glad I decided to go to him.
Dr. Gruenspan was his usual thorough, knowledgable, kind self during this visit. I wouldn't consider going to anyone else, and I've known many fine physicians, for my internal medicine needs.
Dr. Gruenspan is unusually knowledgeable and caring. He's thoughtful and shows a real interest in me as a person. I never feel as if I'm just being processed when I'm in his office. He knows me, remembers what we have said in the past, and gives very clear instructions.
First-rate professional. Office personnel courteous.
The staff was very thorough. The nurse was friendly and the doctor was pleasant and asked alot of questions to make sure I walked out feeling content.
Kind and extremely knowledgeable.
I had good visit with him today. He gave me good medical advice today.
Very caring, patient Doctor. Spent about an hour in my exam room for my initial consult.
The doctor was thorough, patient, kind, and very knowledgeable. I look forward to continuing on with Dr. Gruenspan as a regular patient in the future.
I had a great experience. I find this very hard to come by as I have Lyme Disease and usually only deal with Integrative doctors for their ability to see the body as a whole vs just concerning themselves to their specialty. He completely looked at the whole picture and listened with interest and care. He did the labs right away in house that day and emailed me a week later with results, and what to do. I am no longer in NYC but he would and will be my endocrinologist when I return. Thank you! Highly recommended!
Kind, friendly, and professional. Certainly knows what he's talking about and cares to find the best option for me as a patient. The office staff was also very nice and welcoming. I wish all doctor's office staff were as kind. The wait time was minimal (I booked an afternoon appointment), the office was clean and easy to locate.
very cordial, professional and informative.
Dr. Gruenspan is an excellent physician and medical researcher. I highly recommend him to anyone with endocrinological issues. Highly professional. First rate in every way.
His office is efficient, friendly and caring.
Dr. Gruenspan was wonderful and peofessional. He took his time and listened my concerns. He answered all my question. He is very kind and caring. I am happy that I Chosen him.
Dr Gruenspan is amazing and is really on top of his work i appreciate all his times and efforts
Overall, a great visit! Dr. Gruenspan is kind, patient, and answered all of my questions. His office staff is very nice and professional, and my wait time was reasonable. The facility is also clean. Was a solid visit, overall.
Dr. Gruenspan was careful, patient and caring as a physician. It was my first appointment and I was highly impressed and pleased. Even his receptionist was exceptional in her conduct and performance. The technician was highly skilled and gentle. Overall great experience.
Caring, attentive, spent lots of time with me. I will stay with him and recommend to others!
He was very helpful in making me understand my health. He listens patiently and explains everything in detail. I would highly recommend him.
Very knowledgeable and experienced. Well versed in endocrinology, he listens carefully to the patient. Very attentive to detail. Highly recommend.
The best office ever. In and out. Quick. All offices should be this fast.
I am not a patient who likes my hand held; I do not even think it is worth while to criticize the doctor for his attire or age as some patients have done. I would take experience over pleasantries anytime. Dr. Gruenspan has long practice and that meets my expectations. Why does one even care to screen and pass a judgement on his character as some patients have done? So long as I get what I want out of a physician, that is all that matters to me. If he has his back turned to a patient when he is looking at his lap top, so what. I do not need him to look at me. So long as he is concentrating on my test results and on the conditions of the body, that is what counts. I look for competence and attentiveness when I communicate my symptoms and that much I get when I am in his office. I have not had any serious illnesses to determine if the treatments prescribed are working, but so far I am much happier with Dr. Gruenspan than many other doctors I have had in the past. I like his care. I am not very happy when the phone in the office is not answered but hey, have you ever been in a perfect situation any place? If this is the worst thing you can find to complain about, I do not mind. I know that if I want to talk to the doctor, he does pick up the phone and speaks patiently with me. So far so good.
Great knowledgable doctor who has an equally wonderful staff.
My favorite doctor!
I felt well taken care of! And I liked the Office and somehow that it was easy of access.
He's been great and attentive my whole pregnancy. Staff is sweet too.
He's been great and attentive my whole pregnancy. Thanks
Went in for the first time after seeing a few different endocrinologists in the city. I was surprised at how quickly I was sitting in the room with him and he was taking my vitals and getting all of my information. Not much could be done this visit, since this was an establishing visit to get bloodwork done, but everything was done very professionally and efficiently.
Great appointment. Dr Gruenspan listened to me me carefully. He has an calm and reassuring demeanor. He was thorough. His comments were very informative. The staff was great. I highly recommend him. .
I was disappointed with my visit to Dr. Gruenspan's office, especially after all of the positive feedback he received on this site. I did not feel like
Dr Gruenspan is very professional, quiet and calm doctor, who listens to your complaint and addresses them
The staff was very welcoming. He was kind and informative. Asked questions and was thorough with his examination. Have my follow up next month!
Very thorough & professional, friendly reception staff, small & cozy office.
He was very thorough, and not rushed. Took the time to speak with me and seemed to understand my issues.
He has a very calm demeanor, discussed options, very good visit.
Saw Dr Gruenspan for the first time yesterday for a thyroid consultation and metabolic diagnosis. Great bedside manner. Very thoughtful and thorough. I have not gotten my results yet but I definitely trust him and will continue to see him for my treatment if any is needed.
I highly recommend Dr. Gruenspan. I have seen many doctors for the symptoms I am having and unless a symptom had to do with their specialty, they ignored it. Dr. Gruenspan listened to me. He looked at the big picture and I finally believe we will find out what is wrong. Dr. G is a rare treasure.
Very thorough, very patient and answered every stupid question I had. A really nice man. Highly recommended.
Staff are accommodating and friendly. Dr. Gruenspan explains your situation and answer all questions.
Dr. Harry is super compassionate and and so is his staff are so great. He has been a big help in helping me identify my key issues. Will be returning.
Loved it will make him my endocrinologist officially
Thorough doctor..Took his time and answered my questions....
Very professional and made me feel comfortable. Highly recommend.
Dr. Gruenspan was very nice and attentive and the office staff was also polite. I would definitely recommend him.
Dr. Gruenspan was wonderful. He was very interested in figuring out what was wrong with me and did a through investigation. He was kind and knowledgeable.
This is a first-rate professional. Excellent bedside manner. The office is run efficiently and the personnel there is of high quality.
Wonderful Doctor and amazing staff!!
He was fine. Explained what was happening and why as he went along. They'll send me the results of tests online, which is a plus. I did feel a bit like he was distracted and watching the clock. That being said, I think I received perfectly fine care.
Considerate and informative. Important that he explained everything
Awesome Dr . Knowledgeable and helpful.. Listens well.... I had moved away and have never been able to find one like him !!! So happy to be back with him!
very happy with his concern about his patient. He is accessible and patient in answering your questions. Staff and doctor were very helpful.
Very nice and deliberate doctor. Gave me a lot of time. Very caring.
He was extremely thourough. He sent emails regarding each visit AND followup. I will definitley use him again.
I had an appointment with Dr. Gruenspan yesterday originally for 5PM but I was feeling so terrible - to the point of tears, I called to see if the doctor could see me immediately. The very nice receptionist Danielle made sure that I would be seen immediately and I'm very happy she did because Dr. Gruenspan couldn't have been a nicer and more professional doctor. He was extremely thorough and comforting even though I was a new patient and an absolute mess. Couldn't recommend him enough.
I had a very positive experience. The doctor was very kind and took time to listen to me and to explain things to me. I would recommend him.
Highly professional staff. First rate endocrinologist.
Great he listens and is very patient!
The visit was excellent! Dr Gruenspan pays attention to my concerns and discusses options which many drs do not. The office staff is also very attentive and I was greeted warmly!
the doctor is good but i never got a call back for my test results i have been calling for days and left several voicemails..
Seemed fine. Nice, easy going dr
Very Professional and asked all the right questions. Seemed a bit tired probably because I was his last patient of the day.
Dr. Gruenspan is all around a great doctor. He has been my primary physician for 3 years. He trully cares about your health and well being. I would recommend him in a heart beat.
Very professional, it is a doctor who want to know your medical problems , easy to talk to. I'm very satisfy afterwards. I'm happy to found him.
he is a great professional Doctor. I recommend him 100 % results were ready in less than 2 days I received an email with all the information and how to follow up. the staff OMG they are great! loved it.
Very knowledgeable and takes time to explain to you what your condition may be. Very prompt when sending back lab results and easy to communicate with outside of office visits for further follow-ups.
Great staff, great attitudes, all together very good experience.
Dr. Gruenspan is a fantastic doctor. I most appreciate that he listens, is very attentive, deliberate and thoughtful with his review and suggestions of care. I feel informed and part of a partnership with my care. And he's technology savy- refreshing!
My visit to Dr. Gruenspan was great. He was very calm, professional, yet warm, and most importantly, incredibly efficient. His staff are all also very warm and inviting.
First-rate professional, excellent bedside manner and very courteous and thoughtful staff.
Excellent! He is a warm, concerned doctor who will answer all questions.
Thorough. He actually read/reviewed with me the history and concerns that I listed on zocdoc.
I would recommend this doctor to anybody for endocrinological needs. I did not feel rushed, and his office staff is very pleasant! Positive experience all the way.
I arrived early and was seen at 3pm for a 3:30pm appointment! All my paperwork was accurately transferred from ZocDoc and I was well taken care of by the front desk. Dr. Gruenspan was wonderful, knowledgeable and patient with all of my questions. His Thyroid exam was more thorough than any I have had before and I've been in search of a great Internist/Endocrinologist for a WHILE. I think I found him! Looking forward to hearing his thoughts on my dosage once my blood results are in, and love that they send them via email. How convenient. The Phlebotomist was very friendly and SO skillful. Having a great in-house Phlebotomist is very important to me, so all around very happy with my visit and everything about this practice. The office itself is nice too.
Dr.Gruenspan was kind to me. He listened to what I said about my illness and gave clear answers to all my questions. I am happy with my first visit with him today.
I like my doctor because after lab test my previous doctors never invited me to go to the office for a follow up. If I did not call my doctors after tests, I would not hear from them. Dr. Gruenspan, asked me for a follow up visit to discuss reasons for my abnormalities and tried to offer remedy. I liked that. He is low key, not pushy, does not rush me out, and respond to my questions without irritation like may other doctors do. He meets my patient's needs and I do not have to wait long to see him. I am very happy with choosing him as my phisician.
What a great doctor, explained everything to me thoroughly, listened to my concerns. Would highly recommend. Waited maybe 7-10 minutes to be seen. Nice staff.
It was a very excellent first appointment. Ran a wide battery of tests and received the results very quickly.
very thorough and great simplicity...thank you for your care.
My first visit I felt welcomed the proffesionalism of the front staff amazing. The nurse was great and the dr. Took his time and explained everything.
Very professional and knowledgeable, absolutely recommend.
Doctor was very professional, he answered all my questions and gave me referral for important exams. My blood work was done right away as well. Nice stuff and office.
I really liked Dr. Gruenspan. He allowed me to tell him my symptoms and family history. I understood everything he was saying and had my results very quickly. Will be a regular patient! Thanks!
I have seen other endocrinologists prior to Dr. Gruenspan and I am happy to say he is far the BEST! His staff was very polite and welcoming, the medical assistant who drew my blood was fantastic and the receptionist was very professional and friendly. Dr. Gruenspan is a genius, he answered every question I had (which was a lot) and spent plenty of time with my visit. He was very thorough. I was so pleased with my visit and I look forward to my follow-up visit. I highly recommend him!
I would high recommend Dr Gruenspan. He does a thorough job. He makes sure to get the complete picture picture.He gave me time and answered all of my questions. He and the office staff are professional, polite and accommodating. Again, highly recommended.
He is very professional and caring. He does spend the time to explain the problem and follows up personally. He is one of the best doctors I know. Highly recommend!!!
This is a first rate professional in terms of treatment and research. The office is run in the most polite and caring manner while being supremely efficacious. Highly recommended.
I have see a lot of endocrinologists, and was shocked at the lack of professionalism of the staff - one staff member had me wait to checkin because she was on the phone with her son. The doctor was very odd and asked me a lot of questions that were unrelated to my thyroid disease. He asked if I had any surgeries in the past and I noted my knee. He then asked if I still experience pain and I said I did, he then began to rub my knee that has issues and then my other knee, which I felt was inappropriate and not what I was there for. I would not recommend seeing him.
Excellent attention, nice and clean office, the ladies at the front desk, the nurse and the Doctor are Very good and professional, all made me feel confident, and safe; it was a great experience, Thank you. I highly recommend Dr. Gruenspan MD.
Great visit . In and out. All questions answered. Staff. And dr were fantastic . Thank you zocdoc
Great experience with Dr. Gruenspan. Easy talk to and very speedy with sending back test results.
Dr. Harry Gruenspan is awesome! He listens very intently to what you are saying and he is a very intelligent guy! Highly recommend a visit with him, he is very thorough and will help you with anything you need!
He listens to you most importantly
Dr Gruenspan spent most of the visit with his back to me, facing a computer screen. I'm not a car he's running diagnostics on. Unacceptable.
I am more than satisfied with the care I'm receiving from Dr. Harry Gruenspan. He has my unqualified confidence.
Helpful, listened to all of my needs and responded to my concerns. Excellent post visit follow up via web portal. Appointment was easy to make and all online services made visit very convenient. Would recommend.
I visted Doctor Gruenspan for a check up (type 1 diabetes) and to get an insulin pump. Great doctor, followed up with all blood work results and suggestions. Will definitely be coming back in the future!
gave me a lot of his time and attention and help and he listened and responded
Excellent. There are not enough superlatives for Dr. Gruenspan.
His staff is excellent and very helpful. Dr. Gruenspan is a good listener and he goes over medications that you are taking. Over all he take his time with you. The ladies in his office are great.
Would absolutely use Dr. Gruenspan again. He was very kind, provided me with my results quickly, and helped me very adeptly with my problem.
Dr. Gruenspan was very helpful and thorough.
Following up on results and will see if I continue my appointments. Based on the information I receive (clarity, direction & follow up).
He is, very simply, the best.
After being initially impressed with Dr. Gruenspan's qualifications and intelligence, my enthusiasm has waned. After three appointments I got the impression I was being milked for the maximum number of appointments, not to mention seemingly unnecessary referrals, before we'd finally get to solving my diabetes management problem. I was also hit with unexpected and unannounced fees (a blood drawing fee, in addition to the co-pay?). I think it's time to switch to another endocrinologist.
He is a very good clinician, thorough, kind, always available when needed urgently.
Great doctor everything went well. Very informative about thyroid problems :)
Dr. Gruenspan is a very caring professional who doesn't only treat the symptoms but actually seeks out the root of the patients health problems and is willing to work with you towards your health goals. He is wonderful at recognizing his patients interests and also understanding their histories. He is the first doctor to "give it to me straight" and for that alone I am most thankful for finding Dr. Gruenspan through ZocDoc..
Great visit. Great endocrinologist. thorough, thoughtful and complete
This was my first appointment with Dr.Gruenspan. I found him knowledgeable, extremely thorough, attentive, and pleasant. His staff is highly competent, and kind. I'm delighted to have Dr. Gruenspan as my physician for internal medicine.
It is a pretty good feeling knowing that the doctor you have just seen makes you feel better even though he couldn't tell you what you wanted to hear.
Dr. Gruenspan was very kind and gentle. I did not feel rushed or intimidated by him. He answered all of my questions thoroughly and thought through all of my issues with attention. I would definitely recommend him.
Great, kind and caring doctor.
Always very professional, and patient friendly. Very trustworthy and considerate. He's a true pro.
Dr Gruenspan is great professionally and he has really fully adopted paperless office (from making appointment, to checking in, and all the way to test results and communicating). There is no frustrating spelling, voice mails, and waiting for assistant to find a slot. As soon as I was in office about 5 mins before my appointment I was accepted (no paper work to fill). The whole visit with checkup and blood work was about 40 mins. Truly great experience.
I generally avoid going to the doctor as much as humanly possible because of the impersonal and judgmental nature of those I've seen in the past. Dr. Gruenspan was friendly, thorough, and really took time to ask questions and listen to my concerns. His staff had the same level of professionalism and friendliness - especially the nurse who actually engaged me in real conversation to get my mind off of the needle in my arm ;) Also, and most importantly - I got there early and despite a full office I was seen immediately, no wait whatsoever. For anyone who may have dormant fears about seeing a doctor after a long time - this is the place to go.
The staff was great.. Dr Gruenspan was very professional and listened to every detailed. I will recommend him to anyone.
Very patient and attentive doctor. An office that runs on-time. All in a great experience.
Very open to hear about my condition and provided great care!
It was very quick and the doctor was very professional and courteous. Will recommend this doctor.
He was very professional and understanding of my situaltion. and the staff was very nice.
The office staff is very friendly and helpful! I have been seinf Dr Gruenspan for years and he's always right on the mark with his diagnoses and treatment!
He has a nice, mild-mannered personality. However, I learned that he was not very focused, and is a poor communicator. It was a struggle to get my test results from him, and when he finally sent them across to me, he provided no feedback or guidance, even though there were some red flags in the results. I switched to another Endocrinologist and got much better advice. She was much more thorough, listened carefully and took detailed notes, communicated effectively, and was far more responsive.
I have been visiting Dr. Gruenspan for over 5 years now. I will highly recommend him to all, his knowledge and experience in the endocrinology field, helped save my life.
Ok visit. Have called back multiple times to make an appt and cannot get in touch with anyone. Have to switch doctors.
He is very good, is thorough in his analysis and follows up on previous issues.
Dr. Gruenapan was through, congenial, and very patient with me. He answered all my questions and put me at ease almost immediately. If only all of my ZocDoc referrals were this smooth. Top notch.
Excellent doctor. Excellent medical assistants & support staff. Cordial and warm environment. Highly recommend.
Although I've left a thorough review before, I am still a patient of Dr Gruenspan and really appreciate him and his staff. He is a wonderful, thorough, and compassionate doctor and I wanted to highly recommend him again.
Attentive and professional doctor, did through examination, very knowledgable! Also has an excellent bedside manner and kind nurses.
Very thorough and inquisitive. He asked many questions and thought about all my answers very carefully like a detective.
It was the first time I went to the office, I was greeted kindly by the staff and was seen right away. Dr. Grenspan was really attentive and really listened to me about my medical condition. He was able to take me through the steps to improve my condition. He has great bedside manner and his staff was amazing. I will definitely go back again and I fully recommend him.
Have only had one appointment thus far, but he seems extremely competent, thoughtful, and non-judgmental. My only complaint is that while I was changing back into my street clothes after the examination, some other employee knocked quickly, then opened the door. I'm not very bashful, so it hardly fazed me that someone saw me in my underwear, but I can certainly understand it might bother others.
Such a great visit! He really took the time to go through things with me and weigh in different options/ use tests from previous doctors so I didn't have to pay for anything unnecessary. The staff was wonderful and pleasant to work with - highly recommend!
Very thorough with great bedside manners!
I enjoyed my appointment with Dr. Gruenspan. He really took the time to learn about my medical history and asked every question possible covering every angle. That is very rare these days, so it was nice to have a doctor show patience and concern. He was very thorough in his work and I feel very confident that he knows what he is doing. He also was wonderful in ordering lab work as well as precautionary scans just to be safe.
Excellent. Highly professional. Good bedside manner.
Doctor Gruenspan is very attentive
Dr. Gruenspan was extremely thorough during my appointment. I was taken right on time and he spent the entire hour with me understanding all my symptoms. Him and his staff were warm and welcoming.
Great as always!
Dr Gruenspan is a breath of fresh air. With a situation as complicated as mine, he still takes time to listen, to ask appropriate and thorough questions, and is empathetic and ready to help by utilizing a myriad of approaches. He doesn't make me feel nervous or that he is looking down on me or is rushing me out the door; that is very rare to find in a specialist. I have been to many doctors over the years and know he is a wonderful find, which is especially difficult in NYC. His staff is friendly and helpful, and the office is comfortable.
Amazing doctor. Gets treatment as soon as possible.
Dr.Gruenspan is very knowledgeable and always willing to work with his patients.
First visit. Seemed very interested in my health conditions and helping resolve these problems. Would recommend.
He was thorough, attentive, and had excellent bedside manner. He was very soft spoken and kind. He also had an awesome pinstripe suit and alligator boots. I'll see him again.
Very thorough, knowledgeable, patient and caring doctor. Takes time to listen and orders sophisticated test that many doctors don't use. Very professional and helpful staff. Very short wait times. I highly recommend Dr. Gruenspan to anyone looking for a good endocrinologist.
Very thorough and helpful in addition to kind. I felt in very capable hands.
Front desk staff was courteous and helpful. Doctor was pleasant and took his time asking questions. Good visit.
Very patient and a very nice doctor. Highly recommended.
Dr. Gruenspan is fantastic. Takes the time to listen, ask questions, makes you feel comfortable. Did not feel rushed at all - doctors these days typically don't even take the time to see you anymore - Dr. Gruenspan was the one who took my blood pressure! He actually wants to find you a solution and very knowledgeable.
Gruenspan is very receptive, cooperative, respectful, and most importantly-- HELPFUL. I've been to other endocrinologists and they simply were not willing to run some very simple tests I needed done, even though I have insurance. Gruenspan took my history and assuaged my anxieties about a potential endocrine-related problem by discussing with me the best methods for diagnosis. He was very kind and caring! (Pretty rare in NYC).
Dr Gruenspan spent a great deal lot of time with me and patiently answered all of my questions and addressed all of my concerns.
Dr. Gruenspan and his staff are wonderful people. They are kind, considerate, knowledgable and good listeners.
This was my second time seeing him. He takes times to listen and answer all your questions. He picks up on every detail and goes through all the possibilities. I am amazed at how quickly he is able to make a thorough assessment. I trust his knowledge as a professional. The best thing of all is I can tell he cares about making me feel better. His office staff is the best I have seen. Very highly recommended.
Office was very comfortable, staff very friendly and the doctor was very nice and compassionate. Took the time to ask and answer all questions. Would highly recommend.
Dr Gruenspan is the best doctor I have EVER been too. He is just so nice and smart. He is also very dedicated, anytime I have an issue with my body where something strange is happening(with diabetes) he researches and seeks to get to the bottom of it!! He is so wonderful!! He runs tests and tries to find the best solutions with unreal dedication.
Great. Thank you.
He is knowledgable and took the time to ask questions and listen to my concerns. I am happy to have found a doctor that will help me manage my condition and work with me to find the best solutions.
Wonderful! Clean office, friendly staff, knowledgeable doctor. Highly recommended.
I had my yearly checkup. Doctor was attentive, patient, and knowledgeable. His office also accepts only appointments which is very convenient cause you see what is available.
He was very nice, patient and also seems very knowledgeable. He listened to all my concerns and I really appreciate having a primary care doctor like him.
I like Dr.Gruenspan, I have been going to him for about 8 years, it takes a while to get to know him or understand his personality which can appear detached or unconcerned at first, but I do think he is a good doctor that cares about his patients.
I am very comfortable with Dr.Gruenspan. I believe he is very thorough and analytical, two very important attributes that are needed by a physician in helping to " fix " his patients.
Dr. Gruenspan is very professional and listens to my concerns. He is very knowledgeable, thorough and helpful.
Excellent. Detailed. First-rate professional. Very courteous office staff.
Amazing doctor who really cares about his patients. Highly recommend.
I found him caring, thorough, and willing to invest the time to learn about my entire medical history, and listen to my own thoughts on what factors were affecting the problem I went to see him about.
I highly recommend Dr.Gruenspan. After being diagnosed with a chronic manageable disease many years ago, it still feels wonderful to see a caring, qualified Doctor show a genuine interest in my health concerns. He has a calming effect, listens carefully to you and then asks questions. In addition, the office staff are professional and friendly.
I loved dr gruenspan. He was patient, thorough, calm, and smart. The office and care were great
I was very impressed by Dr. Gruenspan - he listened closely and addressed my concerns. Actually, I was even more impressed with his follow-up. He sent me my blood tests results by e-mail, called in my prescriptions ASAP, responded to my questions by e-mail immediately and forwarded my test results by regular mail. I really appreciated his responsiveness.
He was professional and seemed to know what he was talking about but the bedside manner was not the greatest... a bit awkward and only answered questions in big words. I was a little nervous for the appointment and I guess I didn't end up feeling at ease through the appointment. The nurses and front desk staff were all great though!
Dr Gruenspan is great! He asks lots of questions and seems to really care. I love that there's an option to access our lab reports online as well.
He seemed very caring about my concerns and was ready to listen carefully.
The doctor was very professional. He gave me a careful evaluation. He was very knowledgeable and provided very useful information .
Dr Gruenspan took his time, and didn't rush m. He answered all my questions. He was very nice. I really recommend him
I was impressed with the fact that he listened to what I had to say. It was a most positive visit.
Medically knowledgeable. I wish he had read the medical history I took the time to fill out online before the appointment. The first part of the session was spent with him standing with his back to me while taking notes on his computer. Then he did a competent physical exam and ordered a relevant blood test. I will be able to get the results online through a portal.
Dr. Gruenspan is very thorough and gets results to you as soon as they come in. The nurses are friendly as well.
It was great. Thank you. Very Helpful!
It was great! While it is a shame that the had to type everything into a patient website, it was great. While I do not object to have the digital age, can the physicians maybe SIRI their input into these sites? At any rate, a necessity.
A very good Dr. gives attention to ones problems, understanding and solutions.
The dr was very conscientious and thoughtful.
Great Doctor !!!! Very professional and helpful.
Just my first visit but I'm very impressed.
As usual, he is quick to ascertain, is highly observant and efficient!
The staff was friendly and Dr. Gruenspan was very thorough.
I was very impressed. Dr Gruenspan was very knowledgeable. He was patient and helpful. I recommend him.
I was extremely satisfied with the visit. Doctor Gruenspan was very caring and professional.. He took time to hear me out. His answers to my questions were very insightful. Would refer him to my friends and family. He is an excellent physician.
Dr. Greunspan is a great doctor and very knowledgeable. I was really impressed in the care that he took to understand what was going on and explain it to me. He kept me updated directly and took time to answer my questions.
Best Doctor and staff I've ever met: warm, efficient, professional, and kind.
Love Dr Gruenspan. He is very thorough asked me great questions very relevant to my health.
Very professional. I was very satisfied with his diagnosis. Would refer him to my friends and family. He is an Excellent Dr.
Dr. Gruenspan is a smart, thoughtful physician who hastaken great care of me.
Visit was efficient. Drawing blood was not as easy today as it usually is.
His follow-up is excellent. Best of all my medical team. I really appreciate his availability.
Very professional, thorough and attentive.
Thorough and patient, did not feel rushed. Office staff and nurse Liane especially were great! Definitely recommended.
Dr Gruenspan was very helpful. He was professional and thorough. He took note of my entire medical history and did not just focus only on his specific area. I highly recommend him
I feel very comfortable with the doctor and his staff. This is very important to me.
Dr Gruenspan took a lot of time. He completely reviewed my past history. He was very open to questions. An excellent experience!!
Excellent. Dr Gruenspan took a complete view of all medical problems. He was complete, thorough and reassuring.
Not as good as the first time I saw him. I don't think he listened to me very carefully today. I got the sense that he thought that my problems might be best treated by someone with a different specialilzation but time will tell. I'm feeling a bit friustrated and discouraged now. The first time I saw him, I thought he was wonderfully caring and attentive -- but not today.
He's very knowledgeable and certainly seems to be determined to help out. Unfortunately, he was unable to diagnose my condition, but he spent more time with me than any other doctor I have seen.
While he did step out to take a call in the middle of my appt, I felt he was very thorough and extremely knowledgeable. Overall, happy with him.
He was very thorough and mindful. Loved his Cowboy boots!
Dr Gruenspan was great, he listened to everything i was concerned about and made sure he checked everything out. He answered all my questions and his staff was so nice and helpful, i had a great visit
Amazing customer service from the office staff and nursing staff. Dr. Gruenspan's knowledge and bedside manner is excellent!
Dr. Gruenspan has been my primary care physician for over 15 years. He and his staff are professional, knowledgeable and care about the overall health of their patients. I've referred a number of friends to his practice.
Went very smoothly. Doctor is knowledgeable and helpful. You will not feel rushed.
Very professional, gives patient a good deal of confidence when discussing all medical aspects.
Dr Gruenspan is a remarkable doctor. At times you might wait a bit longer than expected because he takes time as needed with each patient.
He was very considerate and highly interested in my best interest. I was very please to meet a doctor that is truly interested in the well being of his patients. He took a very good amount of time answering my questions and helping me understand my situation. This is posibly the best experiance at a doctor's office that I've ever experinenced. The nurse staff was also very friendly and informative. Wonderful porfessional office!
He wasvery patient and caring. He really took time to listen to me and tries to find a solution To the problem.. very intelligent and knowledgeable
He was very thorough, friendly and helpful. Took plenty of time to listen, look through results, ask questions, He is very expert in his field.
I'm very happy to become Dr. Gruenspan's patient!
I don't expect Drs to be perfectly groomed and dressed, but at least I do expect them to be presentable... Dr Gruenspan's hair was a complete mess, it felt that he was all over the place, and not very organized, even with his personal appereance. He wasn't in a rush, but left no time for questions or asked me if I had any concerns. Will come back for my test results, but probably won't return after that...
I found Dr. Gruenspan to be genuinely caring, knowledgeable, thoughtful, and careful. He took the time to get to know me and he expained things carefully. On the basis of my first visit, I would recommend him warmly.
I believe he is a good endocrynologist. But the wait time in his office is long, and he does not communicate well with his patients. He mostly remains quiet during his evaluation, relaying little of what he finds to you.
Great visit. Everyone super nice n professional.
He's adorable----and smart!
Very kind - listened to me and thoughtfully worked through my case. Didn't dismiss my concerns or questions. Was very thorough. Staff were also all very kind.
It was a very productive visit. Dr gruenspan was complete and fully addressed my concerns. I highly recommend him.
The doctor allowed me to express my concerns. He was very thorough. He was thoughtful. He answered my questions. I was very satisfied
I have a complicated history and Dr Gruenspan tok a long time to get it all and put everything together. He did extensive additional testing to figure out what was going on.He gave me thoughtful and not pat. I feel very confident with him and recommend him.
I was very pleased. Dr Gruenspan was thorough and thoughtful.I was impressed by his assessment. The information that I got from him really helped me.
The reviews I saw on ZocDoc for Dr. Gruenspan were mostly positive, so I thought I would give him a try. I didn't have to wait long but that was the only positive thing about my visit. He took my blood pressure with an automatic machine and left the cuff on, so the machine kept going -- 4 times! When he finally got around to examining me, he stuck the ear scope in my ear so hard that it hurt. He told me the results of my test would be back in 48 hours, but he would be at a conference, so not sure when he'd get them to me. Then when I asked him how long I'd be contagious, he stumbled over the question. I don't think he knew the answer! If I didn't find him on ZocDoc, I would have sworn he was posing as a doctor. I will never go back.
Dr. Gruenspan was patient and listened to my issues. i hope he will be able to find out the underlying cause of my medical issues. The office staff were very friendly and helpful.
Dr. Gruenspan was very thorough and very nice. The girls in the office were helpful and extremely friendly. Definitely recommend this office!
While the exam was professional, the follow up left a lot to be desired. I went to him because I was very concerned and stressed out about a medical condition, but I was the one who had to call for the test result - I received no callback and I received the results with the recommendation for further test through the mail a WEEK later. So. if you have no concerns he's find, but, if you are worried about something, which is the reason one would see an Endocrinologist, he's not the doctor to see.
He's a bit odd... Seems to interrupt his own train of thoughts a lot...
Dr. Gruenspan was very thorough with questioning, listened well and provided good information to me during my visit. The nurses and front office staff were very amicable. The office was clean and modern. I highly recommend Dr. Gruenspan.
Very thorough doctor, took his time asked many questions. Highly recommend him :-)
Dr. Gruenspan was fantastic - I highly reccomend him. He took his time thoughout the appt, and I didnt feel rushed at all. HIs office has a great online system for sending test results in lieu of returning back to the office. 2 thumbs up
very knowledgeable and professional. was willing to spend a lot of time with me and answer all questions.
I was thoroughly impressed. Dr Gruenspan was very knowledgable, informative and complete. He answered all my uestions. I recommend him without reservation
Dr. Gruenspan is very professional and thorough. I went to him with seemingly simple symptoms which most doctors simply disregarded as a potential problem but Dr. Gruenspan listened with interest and performed tests to diagnose my problem. It has been 6 months and I started showing improvements almost within a month. I would definitely recommend him.
I'm not sure what happened this time. Either the dr was distracted or last time was a fluke. I was so impressed with the time that was taken with the last exam. This time I waited over 40 minutes, and then was asked to step out of the exam room for something. The dr finally came in, and then fiddled with the computer for about 10 minutes, asking me 1-2 questions with his back to me. Then left, came back 20-25 minutes later, and was interrupted and left again. A little disappointed - I expected better.
I was very happy. He took time to find out what was happening. He was thorough and explained everything to me. I have worked for doctors and could tell he was really good.
Really helped me with my problem. Quickly diagnosed and treated me. I was impressed with his experience care.
He took very long to get to his point, told me he would be back in 5 minutes and took 20. He seems a bit too old to be doing this, perhaps he should retire. He didn't seem 100% confident in what he was saying and made me feel uncomfortable. He also made me tell him everything that was on the form I had written. I don't understand why he couldn't just read the form. It made my appointment 1 hour longer than it needed to be.
He was very nice and he answered all my questions
the receptionist was awful doc is really well educated and helpful staff sucks beaware
He never followed up with results i called several times. Toldme to drop off xray i did they wouldnt take Went to a different Dr. And received results within 2 days
He was very thorough, definitely a positive experience.
He is very nice doctor,he ask me questions I asked questions and I got my answer. Didn't push so I can take any medicine.Will watch the progress and continue the follow up. I will recommend him.
This doctor is very thorough. He took the time to ask me questions to try to understand the problem
Very professional and friendly staff. Pa who got my info - and my blood - was great. Dr was very attentive and took his time. Aske questions that prompted responses. Would have appreciated a bit more feedback on my responses, if it meant something - but I didn't quite know what questions to ask either.
Dr. Gruenspan is a very smart, savvy doctor. My only complaint is that he needs to manage his office better. Sometimes his staff doesn't call back. It's hard to schedule appointments. Hopefully it'll be better now that he's on ZocDoc.
I am very happy I went to Dr. Gruenspan. He was very kind, open, and thorough. I appreciated that he gave me a lot of time. His answers were considered and to the point. I appreciated his thoughtfulness, and it was clear that his answers were directed specifically to my case. You can tell he cares about what he does and knows what he is doing.
I was very impressed with Dr. Gruenspan. He was very complete is assessing my medical history and health. He answered all my questions. His fund of knowledge was very impressive. He was a bit quiet. However, in talking to him it was obvious that he was listening closely to what I was saying.I highly recommend him
Doesnt treat patient as a person, seems to forget some people aren't comfortable with everything... Would rather have found someone else... Staff is impatient as well and doesn't seem to care much for patient modesty.
Staff was friendly and efficient. Doctor seemed disinterested.
Dr. Gruenspan was very kind, open, and thorough. I appreciated his thoughtfulness and the time he gave me. He carefully answered all my questions, and it was clear that his answers were not generic but specific to me. I am glad I found him.
very nice people in the office
very intelligent and thoughtful- doesn't say a lot, but what he does say is valuable.
Dont think I was diagnosed correctly.
Dr. Gruenspan definitely takes the time to answer any and all questions you may have. I've never gotten the feeling that he's rushing me out the door, as I have with other endocrinologists. He's a bit eccentric but he knows what he's talking about. Recently he called me on a Friday afternoon to discuss test results, and the conversation lasted well over 15 minutes because I had so many questions. You can tell he cares about what he does.
very thoughtful and thorough- have to ask him a lot of questions, but he knows a lot!
Dr. Gruenspan has a nice staff working for him, his office emails test results, and he was very thorough. I would definitely recommend him :)
I've been to a number of doctors over the past few months, and some form of unhappiness/frustration arose with each one preceding Dr. Gruenspan. This endocrinologist is extremely knowledgeable and truly cares for his patients, ensuring that his diagnosis is indepth and accurate (he tested for important & relevant hormones which none of my previous doctors even seem to have heard of). He doesn't push treatments which I'm uncomfortable with and doesn't rush appointments at all, thus granting me a full understanding of everything in progress. Plus the staff is a pleasure—kind, considerate, and full of great conversations. I've already had a couple of appointments at this office and will definitely continue to see Dr. Gruenspan for as long as I need.
I was 30 minutes late (bad weather and traffic) and called. Dr. Gruenspan saw me anyway without rescheduling. And I did not have to wait long! I'm rescheduling another appointment for follow up and because there wasn't any hassle!
Dr. G was taciturn but listened carefully, was very knowledgeable and gave sound instructions. This was my first visit so it's too soon to tell for sure, but he seems very good!
I did not feel like the doctor really listened to me. He was filling out forms on his computer while talking to me. Most of the questions he asked me were the same ones the nurse had asked. After a bunch of tests were done papers with the results that I watts clarification on were sent to my house. I called the doctors office twice and left a message (once on a machine and once with the receptionist) but no one ever returned my calls.
Really takes the time to understand what's going on. And he wears cowboy boots.
Totally recommend him !
He has a very pleasant bedside manner and I want him to be my Primary Care doctor.
i had to wait for 45 minutes before i saw the doctor, but the doctor was really knowledgeble and patience. He gave me enough time to hear me out and answer my querries.
Very thorough with his assessment. Staff were very helpful and informative.
