Verified Patient Reviews
Love Dr. Yen. Always professional, helpful and caring. Highly recommend him.
Great dr! Took time to explain everything to me in great detail - I absolutely recommend Dr. Yen!
Very helpful and thorough
The appointment was not rushed. He took time to explain everything and answer all my questions. He called the facility in NJ I used for a preliminary test to see if they performed a follow up-most unusual
Dr. Yen is a great communicator and a hands on Doctor.
Dr. Yen is one of the best doctors I've seen in a long time. Informative, knows his craft and took true genuine interest in my concerns and finding a solution. I would recommend him to anyone I know.
Dr. Yen is a gem of a doctor: thoughtful, considerate, reads up on the latest literature, and is kind and gentle in his bedside manner. I've been seeing him for a decade and have no intention of looking elsewhere for an endocrinologist.
Dr Yen is the best!
I'm almost tempted not to tell anyone what a great doctor Dr. Yen is because it's so hard to get an appointment to see him! But the word is already out clearly. I've been seeing Dr. Yen for over a decade for thyroid management and he's an amazing, thoughtful, gentle, caring, responsive, and collaborative doctor who is truly passionate about the medical care and well-being of his patients. He stays up to date on the literature and the new treatment approaches and is always willing to offer new options and ideas to manage conditions.
He's a very observant doctor who listens to you, which seems rare these days. Also, the front staff were very friendly.
Doctor Yen is great. Very attentive and helpful.
Excellent doctor - really takes his time to thoroughly assess and listen to all your concerns - he's very reasonable with tests and treatment as well - nothing over the top, nothing unnecessary and he doesn't need you to follow up every single week. It can be a little hard to get in touch with him as sometimes it feels like his office is understaffed. Every time I call I'm put on hold for at least 5mins, no matter what time of day. But when you do actually see or speak with him, you feel as though you're his only patient. I've recommended him to so many people. Beautiful, clean modern office as well.
Dr. Yen is good. The office staff can be very unprofessional :(
I highly recommend Dr.Yen. Received very professional service. Was seen right away and was very satisfied with his expertise.
Dr. Yen is a very caring and thoughtful clinician. I've been seeing him for over a decade. He's a patient listener, recalls progress over time, and is always provides individualized options for optimal health management. He's fantastic! Highly recommend.
I arrived early, but still saw the doc late. But you know what? Doesn't matter. He's worth it!
Love Dr. Yen. He's the best.
I have been a patient of Dr Yen's for the past 10 years. He always takes time and looks at the whole picture regarding one's health and well being. He explains everything and has a wonderful ability to listen as well to one's concerns. He follows up as well as he says. I highly recommend him.
He is erudite and caring and full of useful information. He is my favorite doctor.
Very friendly receptionist staff and nurse. My visit with Dr Yen was quick and efficient! Overall a very positive experience.
Great doctor who was patient, thoughtful, and attentive. The wait for the appointment took forever, though, and the front desk can be a pain to deal with. After a blood test, I called the office (as instructed) and was told that he would call me back. After not hearing back for a week, I called again, and the person informed me that he was on vacation but would leave a message to have him call me back. After another week and still no call, I called again, and the admin was surprised to hear that I had called previously as there were no messages for him to call me! This time, she actually took a message down and he called me later that day. Dr. Yen was great, though the rest of the experience left much to be desired.
Extremely wonderful experience with Dr. Yen. I'm so happy I decided to switch endocrinologists. Dr. Yen was extremely helpful and explained every little detail.
Nice & straightforward.
Getting to see Dr. Yen on the appointment date was almost instantaneous. There wasn't much wait. However, getting this initial appointment took time. I had to schedule two months in advance. But that just goes to show you how good he really is. Dr. Yen is knowledgeable and courteous. He help me understand my treatment and started me on it immediately. And best of all, he is transgender friendly. If you need an endocrinologist, this is your man.
I worked with Dr. Yen for over a year. He was caring and concerned at every visit. I never waited more than 10 minutes for my appointment. He always explained things to me in a way that was understandable, but never talked down to me. He listened to my concerns, and went over all my options at every phase of treatment. It is very hard to find good Endocrinologist, but I would certainly recommend Dr. Yen to anyone who wants to finally find a solution to their medical issue. He is a rare gem.
Dr. Yen was awesome. He explained all of the bloodwork numbers to me in a way that no doctor ever has before. He seemed genuinely interested in making sure that my numbers are good and that I'm feeling well.
Dr. Yen was professional, kind, clear; everything you need a doctor to be.
Great as always!
Dr. Yen is patient, thorough and takes the time to answer questions. He's the best!
Dr. Yen was understanding, professional and seemed genuinely concerned about my health issues.
Great doctor, very knowledgeable, explained everything to me about my treatment options and condition in a very easy to understand manner. Clerical staff was very courteous. Highly recommend this doctor!
He made me feel really comfortable, which is important on a first appointment. Also, the woman who took my blood was so good at it, it was almost painless and over before I knew it!
Excellent visit. Caring physician as well as excellent clinician. I look foward to my visits with him !
Dr. Yen was very friendly and knowledgeable. He answered all my questions with patience and detail.
He was okay, but I wish he had spent just a little time to find out my hypothyroid symptoms before just refilling my previous prescription. When I asked about another supplemental medication, he just asked how much I wanted, and prescribed that as well. I felt like I got nothing but a refill out of the visit. Bad form for the "leading endocrinologist of NYC", or maybe it was because I was his last appointment of the day. Either way, I wasn't impressed.
Very Professional. He broke down everything into very easy to understand terms. Made sure I understood everything that was going on and what to expect.
Super professional, doesn't waste your time but gets as technical as you want him to, and absolutely took seriously my input & pre-research of the potential conditions or testings I expected to take. I was right about most of them, and he added a couple more tests for completeness. Very practical and efficient, but definitely not in that way that makes me worry he's going to overlook anything!
Very thorough. He gave me the right information and then some more. The staff was incredible too and so were the premises. I have been dealing with thyroid issues for at least 20 years, so I really appreciate a physician who takes the time to analyze and explain symptoms.
I've been with Dr. Yen for over a decade and would recommend him highly. Thoughtful, patient, caring and very good at explaining key medical info. He partners with me in managing my health and truly takes time to evaluate all available info before suggesting care and management approaches.
This is not a good doctor and his staff is even worse. I think that he's bright, but bedside manner is chilly at best. Worse is the follow up after a visit. If you have hypothyroidism and are not feeling well, follow up is critical after blood work to determine if meds should be adjusted, etc. In addition, my blood pressure was almost dangerously low when I came in for the visit. He was impossible to get through to after the appointment to find out about blood results. He called once, didn't leave a message, and the staff rudely kept insisting that he had delivered the blood results. In addition, they have an attitude with you that you are only entitled to vague information. They don't know anything and definitely have the attitude that he is too important/busy/uncommunicative with them by extension his patients. After the visit, I remembered that I had been diagnosed with hypoglycemia when I was younger, and was thinking that might be the cause for my exhaustion. Although I explained the importance of this fact to the staff on the phone and that I hadn't told him about it - and he's an endocrinologist who treats that - and wanted to touch base on the phone about whether that might be happening now, they were unconcerned since he is SUCH A BUSY DOCTOR and they have no idea when or if he can even return calls. Go to another doctor! This relationship is one that is going to last a long time - some people use their thyroid doctors as their internist - it's that important. Go to someone who isn't just going through the motions. Your whole health can loop through this one doctor - he is not going to take the care to get it right.
Good listener, excellent knowledge of the practice
Dr. Yen was efficient, highly knowledgeable and approachable. I felt comfortable with him immediately. His staff was also caring and attentive. I give Dr. Yen the highest recommendation.
Doctor Yen was not in a hurry, listened & asked lots of questions. Facility: Quick attention. Clean new facility. Location was close to home.
Knowledgeable and easy going. I relax when I am in his office and he has a superior staff.
He is a true professional who actually cares about his patients and their concerns. That quality is quite rare in the medical field.
great, kind and thorough!
Dr. Yen is always professional and extremely knowledgable.
Dr Yen is great. He doesn't rush, asks questions, actually listens to the answers. Looks at your overall health, not just specific issues. I highly recommend him.
Excellent Doctor. I just had my second appointment with him for a follow up; I was surprised that he remembered my health issue after almost 7 months. He's the best.
Today was my first visit with Dr. Yen. I was nervous at first because I have tried a few doctors and was disappointed. As soon as he came in and we started talking I felt very comfortable. He is very well informed, answered all my questions. We even discussed other treatment options for my diabetes (which now I am highly considering). The staff is very nice and personable. His assistant Aaisha is very professional, friendly and made me feel very comfortable. Needles to say I am looking forward to my next visit with Dr. Yen.. I highly recommend this doctor.
Great, friendly accommodating staff. Clean, modern office. Prompt attention and service. Thorough exam with proper explanation of possible diagnoses and treatments. More than satisfied! Would highly recommend.
I thought Dr. Yen was knowledgeable and concerned. I was seen early. I found him and his staff very professional staff. I certainly will see him again and use ZocDoc. I am very satisfied.
He is a brilliant, thorough and very compassionate doctor.
Very punctual. Dr. Yen and his staff were professional, kind and knowledgeable. I would definitely recommend him.
Dr. Yen is personable and knowledgable and his staff is kind and friendly. This was my first appointment with him and he took his time, asked me a lot of questions, and he explained everything thoroughly and in a way I could understand. I have been looking for a good endocrinologist for a while, and I'll definitely be going back to him.
The visit was fine. The front desk was extremely busy and seemed overwhelmed. Prior to this visit I had an issue with one of my prescriptions because the front desk kept telling my medical provider that I wasn't in their system.
Dr Yen made a great impression. He is clearly a very experienced endocrinologist. I would highly recommend him.
I have seen Dr. Yen for a number of years and have always enjoyed every appointment. Never rushes you through your appointment and will mail out blood work RXs instead of making you come in to pick them up.
He is the best doctor I've ever had. He spent 45 minutes talking with me today about insulin and how it effects me differently at different times of day and with different levels of activity. I've never had a doctor who took so much interest, and was also so smart He also helped me by upping my prescriptions once more. I will continue to rave about Dr. Yen. Best Doctor I've found on ZocDoc!
very knowledgeable, and willing to explain many different aspects about they thyroid and its inefficiencies
i really appreciate the depth of his knowledge of my condition and the variety of potential treatments he is versed and experienced in
Excellent. Dr. Yen was very kind and answered all of my questions thoroughly. I would highly recommend him to fellow transgender patients.
This was my first visit to Dr. Yen. I had to wait several weeks for an appointment, but once there I did not feel at all rushed. I had brought several pages of previous test results. Dr. Yen took the time to go through them, to explain some of the readings, and to answer my questions. Since I am prediabetic, he let me know that taking medication to delay onset is an option, but respected my preference to rely on diet and exercise. He is not an authority on some of the alternative treatments, such as supplements or the more extreme diets, but he said there was evidence that some of the supplements helped. I will continue to explore those on my own. Overall, a very positive experience.
Very professional. Explains you the details clearly about whats going on with you and why some tests are needed.
Very good doctor, knowledgeable, explained everything to me about my condition, didn't feel like my appointment was rushed. He forgot to do a certain blood test and called me to give the results instead of having me come in again. I don't judge doctors based on waiting time (I don't think that determines how good a Dr. is) but for those who find this important, I saw the Dr 2x and both times I was seen within 2-3 mins of waiting.
Dr. Yen and the staff at Beth Israel were very cordial and professional. God bless the whole staff, Dr. Yen, Dawn, the front desk receptionist, and all who were there. Even though I am worried about my condition, I have such a surreal sense of peace with the staff, which is a feeling I never experience with specialty doctors or clinics.
This is my first time seeing Dr. Yen, but everything was excellent and I look forward to future visits to come!
Dr. Yen was very professional, nice, and asked the right questions. He has great bedside manner and really took his time to listen to my concerns and then explain things to me in layman's terms. The office is also very clean and the staff was nice and friendly.
Did a great job explaining everything to me and even though I probably didn't even need to see him, he went out of his way to explain everything to me.
I have complete confidence in him.
Always a good visit, usually not that long a wait (and I'm usually early).
Been to him a few years ago then lost my insurance...now I have insurance again and went back to him...He's great
EXCELLENT DOCTOR. KNOWN AND HIGHLY REGARDED BY SEVERAL OTHER DOCTORS I'VE SEEN. HE CALLED ME WITH MY BLOOD TEST RESULTS INSTEAD OF HAVING ME COME IN FOR ANOTHER $60.00 CO PAY WITH AN APPOINTMENT IN THREE WEEKS TO DO BLOOD TESTS AGAIN.
Dr Yen is the best doctor I've seen. He takes the time to talk to you about anything you have questions about and does so in a professionally and friendly way. I had a prolonged health problem that was difficult to diagnose and he worked with my other doctors to figure it out and get me on the right path. I don't know what I'd do without him!
All the staff were very nice,the nurses and doctors were excellent
I picked Dr. Yen based on his ZocDoc reviews, and wasn't disappointed. He was friendly and easy going and saw me right away. He took plenty of time to answer my questions and gave me some good advice.
Dr. Yen was great! The receptionists were very attentive and nice. I recommend this place to anyone looking for a consultation. My only issue was the wait time because I am strong believer that if you have an appointment at 8am, let it be 8:14am the latest, not an half hour after 8am or longer.
He listen to my problems and tried to help me to the best of his knowledge
This was my first and only visit with Dr. Yen to date, but I have a follow up appointment scheduled. I felt very comfortable with him. He was very attentive, and I did not feel rushed. I was seen right away. He seemed very interested in my concerns. I would recommend him, based upon this visit.
Dr. Yen is well-informed and thorough. He listens well, processes everything, and has helped guide me to a path to health.
Caring and thoughtful physician. He takes time to explain medical concepts, and listens carefully to his patients. He has great followup post-appointments and always has the patient's best interest in mind in any care decisions he makes. I've been seeing him for 13 years and trust him completely.
Dr Yen was great! Patient, attentive. It's only natural to have some anxiety when you dint understand what's going on in your body, but he explained everything really well and put me at ease. So glad I found him!
Very observant Doctor. It was a good experience for me.
Dr. Yen is easy to talk with, seems extremely interested in all aspects of a diabetic's life and most importantly, he is extremely knowledgeable and caring.
The news he gave made me very happy.
Dr. Yen was very thorough and very knowledgable. I went early in the morning so the wait was zero. I found out everything I needed to know. He is highly reccomended.
Informative and helpful.
Very patient and knowledgable.
Have been a patient of Dr. Yen for over 3 years. Highly recommend him.
Dr. Yen is fantastic. I can't imagine seeing any other Endo.
He took the time to explain treatment options. I didn't feel rushed. Staff were very friendly and attentive as well.
He was a bit rushed on the day I saw him, but aside from that, he was very kind and professional, and his office staff was courteous. Would recommend.
Was my first time to an endocrinologist. Dr. Yen was INCREDIBLY attentive. He spent an extended amount of time with me explaining everything in great detail. Will be going back here.
He listens to you gives you options and explains things to you.Excellent Doctor.
Dr. Yen was very informative and comforting. He listened to all my concerns and address them all.
I trust Dr. Yen and I place all my confidence in him.
Doctor Yen is smart, very knowledgable, a good listener, and an overall good man.
My visit with Dr. Yen went very well. As usual, he was very thorough and answered every question that I threw at him. The staff is extremely pleasant! I highly recommend him.
Dr. Yen was very kind and informative. He took the time to go over my results from my previous blood work and thoroughly explained what I may expect in the future. He also made me feel comfortable and at ease, allowing me to walk away with confidence. I will surely recommend him to all of my friends and colleagues.
He was very warm and friendly. I felt he understood my issue and was able make me feel he could help me.
Dr. Yen has been my endo for many years, and my PCP for a few. I am a big fan of everything about him as a doctor and a person. He is the best listener of any doctor I've ever seen. I have never once sensed that he's dealing with me in a rote or default way; rather, he's very specifically attuned to me and my health.
I have all my confidence in him.
As always, Dr. Yen was informative and caring. Very competent and professional physician.
Very nice doctor! Took his time and answered all my questions. I found him thoughtful and thorough. He inspired trust with his knowledge.
If you need an endocrinologist, there is no better choice!
Very thorough, asked a lot of questions. I didn't feel rushed at all.
Dr. Yen and his staff were prompt, professional, and helpful. He took the time to explain the details of my medical situation, and his office does blood work right there. Dr. Yen personally returned my phone call about the results of the blood work, and his office mailed me a print out of the results without me requesting it.
Dr. Yen was very understanding - he listened closely and patiently to my laundry list of questions/concerns. He did an excellent job investigating my condition, and explained my options thoroughly yet simply. I waited less than five minutes to see the doctor, and didn't have to wait at all to have my bloodwork done right there in the office lab. Dr. Yen and his staff were friendly and efficient - I would absolutely recommend them to anyone!
Dr Yen has provided excellent care and support to me, both in person and in follow up on the phone. I came to him about conditions I've had for awhile and he took the time to get my complete history and acknowledged that we were both experts--he as an endocrinologist and me as an authority on what's going on with me and my past labs, etc. So refreshing! He's smart and thorough and in my case has been very helpful in finding the right surgeon for my next steps. Side note, the nurse in the lab was a first rate phlebotomist--painless stick on the first try which is so rare for me. Great experience all around.
He is by far one of the best Dr.'s that I have seen! He knows his stuff and is 100% caring! He took his time and was very thorough. I have already recommended him to all of my friends here in NYC. He is amazing.
This was my initial visit. Dr. Yen was great. He was very informative and took the time to listen to my concerns as well as go through all of my medical records. The staff was also extremely friendly and helpful. The facility is also very clean. I highly recommend him.
Everything went very well and expedient. Dr. Yen was courteous and a good listener. His staff was very professional and efficient.
The doctor was personable, thorough, and inspired confidence. The woman who drew blood afterward was briskly efficient. However, the clerical staff is disorganized and unprofessional. When I walked in, the receptionist was having a meltdown, complaining loudly, mainly in Spanish, about how overwhelmed she was. Getting my paperwork in order was a major drama. I was promised follow-up within a certain timeframe; never heard. Called several times, winding up on hold indefinitely, having the call dropped, getting clueless answers. Didn't get results till one week after they were promised, and only through my dogged persistence. If the staff were as good as the doctor, I'd recommend without hesitation, but I have no tolerance for this type of nonsense.
Dr. Yen is fantastic and extremely professional. Very through, takes your questions and is very concerned about the pt.'s overall care and treatment. Highly recommend Dr Yen.
Dr. Yen was running behind, but still took his time with me. He seems very knowledgable and gave me more information than the average doctor. He also listened to everything I had to say and all of the questions I asked. He is a bit talkative, so I did need to be assertive to make sure I got my questions in.
Dr. Vincent Yen is very professional, caring and helpful. He was very meticulous going over my medical history. His examination was Thorough. He is very easy to talk with and answered all of my questions. I will hightly recommend Dr. Vincent Yen.
Dr. Yen is amazing. I've been seeing him for over a year. He spends an hour with me each time I go in for a consultation and has helped me in lowering my A1C. He has extensive knowledge of beneficial products for diabetics.(He recommended a contineuos glucose monitor for me which I had never even heard of and it's worked out great). He will take the time to call your insurance and discuss with them what you need precertified in order to maintain your health. Seriously, for a Doctor of his caliber I am amazed he even takes insurance.
Dr. Yen was the most thorough and knowledgeable doctor I have seen in the 5 years I've lived in NYC.
Incredibly knowledgable about the thyroid function and nodules. Made me feel at ease yet was as honest as can be.
Expert and knowledgeable. Put me at ease. I was taken in a few minutes before scheduled time. When does that happen?
Dr Yen first treated me about 12 years ago for a thyroid condition. When my primary doctor left the practice, I chose Dr Yen because he made me feel very comfortable. Today's visit was the same,, very comforting.
I just saw Dr. Yen today and he was extremely knowledgable. The reception staff certainly could have been friendlier, but my appointment was on time and the doctor took plenty of time to answer all of my questions. I would definitely recommend him.
Dr. Yen was great! He was very friendly and personable. He was extremely thorough in his explanations, asked a lot of questions, and answered all of my questions (most of which my primary doctor couldn't or wouldn't answer). I went to him as a specialist and am considering switching to him as my primary doctor.
Dr. Yen is a excellent doctor and is helping me control my diabetes. Miriam Seaton
Definitely took the extra step to really take care of me
He is competent and kind. Very impressed.
The whole staff was really gracious and kind. Dr. Yen talked to me for a long time and really made sure I understood him.
Really great office staff. Everyone was pleasant and friendly. And best of all, I wasn't parked in a waiting room for an hour or so. I was seen on time.
Fantastic doctor! Takes his time to explain everything and is very thorough. Really listens and is compassionate.
Dr. Yen is wonderful. His office staff is not. They billed my old insurance even though I presented and they xeroxed my new insurance card. I fixed one bill, am working on the lab bill. Also, in the past, I needed to have renewal prescriptions called in to my pharmacy. Twice they called in an incorrect prescription and it took between one week and ten days to be corrected, costing me another co-pay. If I didn't respect Dr. Yen, I'd be out of here.
Dr. Yen does not seem to care too much about his patients. I have seen him 3 times for a thyroid issue and he seems very disorganized and does not seem to listen to what you have told him in terms of symptoms and concerns you may have. It is also near impossible to get in touch with him to discuss results. Do not deal with the frustration of seeing Dr. Yen. Find a doctor who cares and will spend the time to help you. Also continuum health, in his building, messed up the insurance for my blood work and now I am in the painful process of getting that sorted out with them.
Very professional and friendly.
Incredibly comprehensive, thoughtful, knowledgeable and kind. Fantastic physician.
Great experience, such a nice guy.
I saw Dr Yen on Thursday and started recommending him the next day. He is experience,knowledgeable and more importantly up-to-date in the care and treatment of his specialities.
This is the best endo I've been too and I've been to many! He listened (rare)and really did a through eval. I am looking forward to being his patient!
Dr Yen was informative, and very helpful!
I had my first appointment with Dr. Yen and he was fantastic. He spent nearly an hour with me going over my various symptoms and prior medical history. He is very intelligent, understanding and communicates medical terminology and processes thoroughly.
Dr. Yen is very informative, thorough, and clear in his explinations. Wait time (especially for a new patient) was a lot faster than I expected, especially considering I did have a late evening appointment.
(update) Dr. Yen did an excellent job in getting down to the bottom of what was causing my symptoms. When things got really hairy one Friday night, he called me back and made sure I saw the doc on call that weekend (who was also terrific). Thanks to Dr. Yen, I am feeling much much better. He really cares about his patients. I wholeheartedly recommend him and his practice.
I was amazed at how thorough Dr. Yen was. Even though we had basically ruled out any thyroid problems as the source of my depression and fatigue, he took the time to discuss other possible causes outside his field. I have never seen such genuine enthusiasm in a doctor for his field. More, he never talked down to me and helped me to understand my charts and form my own opinion. Though the nature of my problems prevented him from helping me, I am deeply greatly for the time he took with me.
I only saw Dr. Yen for one visit, but he was very attentive and took a lot of time with me going over my complicated medical history. Fair warning - He's all business. If you're looking for a sympathetic ear, then you might want to consider visiting someone else. For me though, professionalism and attention to detail are the most important factors given my situation. Quick shout out to the front desk and lab attendant who were very pleasant and helpful.
Vincent Yen was very quick and helpful. I got all my tests that i needed done to clear my surgery within 15 minutes. Excellent doctor straight to the point and i would recommend him!
Thorough and knowledgeable. Really nice guy.
He's a very good and thorough doctor. He's my doctor now!
