Verified Patient Reviews
I found Dr. Leventhal to be a breath of fresh air. Very knowledgeable and thorough. I would absolutely go back or recommend my friends and family.
Great experience as a first time patient
Great overall experience arrived early since I was a new patient. Filled out the insurance paperwork only a couple of pages. Met with the doctor in his office at my scheduled appointment time. Went over my family medical history took me into the examination room. Did a complete physical exam, couldn't do blood work since I had recently eaten. He referred me to a lab to conduct my blood work and additional tests for the next day. Talked again briefly afterwards and is referring me to other specialists to complete my overall physical. Very easy to talk to and made me very comfortable the entire time. Looking forward to having Dr. Leventhal be my doctor for years to come.
Very personable doctor, would definitely recommend to a friend.
Dr. Levnthal is one of America's leading physicians and has a great personality, which make for a terrific combination!!!
Very friendly and easy to talk to which helps ease nerves about health.
My first visit with a new doctor always has me anxious, but I have to have that I loved the interaction and visit! Dr. Leventhal made me feel very comfortable and relaxed while definitely addressing all my concerns and questions! Excited to have him as my doctor for the foreseeable future.
Terrible diagnosis. Could not find an answer and so concluded it was all in ly head. He would not let me finish my sentences and would come to his own conclusions before even listening to the whole case. Too old and proud for the game.
Super nice and caring. Recommended.
Very good experience. Unfortunately, I've moved away and will be going to a different doctor.
Excellent experience here! Dr. Leventhal is amazing! So kind and patient! I highly recommend him!
Fabulous bedside manner and smooth office admin.
Excellent experience with the doctor for the first time. Very helpful, kind and personable.
Dr Levanthal is always honest, friendly and very thorough.
Doctor Leventhal is very professional and knowledgeable and has a very friendly manner. His first floor office is cozy and convenient.
What a lovely person! He was very caring and concerned, thorough, and respectful. I felt confident seeing him. Highly recommended.
Very knowledgeable and pleasant. A great doctor!
Doctor Gerald is wonderful...
He is attentive and wonderful.
Dr. Leventhal is always friendly, helpful, a good listener and a pleasure to see while also being quick and efficient. He's not afraid to prescribe rest and fluids before resorting to medication. A great doctor.
Doctor was fine but the wait was unacceptable. Old dingy office. Would not go back unless dire need. I only booked him because my primary doctor had no availability.
I've seen Dr. Leventhal a few times now, and every time I see him, I have a great experience. He is understanding, and never makes me feel silly for asking weird or otherwise seemingly minute health questions. I always leave his office feeling that I am on my way to being healthier.
I normally don't write reviews, but I just had to this time, to prevent people from the mistake I made. When I chose this location, being the UES, I didn't expect the service to be the worst I have ever experienced. Long wait time (I came first, but they let 4 other people, who came after, ahead of me), to do the blood tests they send you to a different building where you wait 2 more hours (total time at the doctor's: 4 hours just for an annual check up), promised return calls the doctor never returned, staff hung up on me in the middle of the conversation... Will definitely not go there again, and recommend everyone else to avoid seeing that doctor! I am sincerely surprised about positive reviews left about that location here. Total disappointment to me, and from what I saw, to other clients who were there at the time. The worst customer service you can possibly expect.
Dr. Leventhal is extremely personable, very thorough and quick to follow up. I highly recommend him!
Doctor Leventhal comes across as both knowledgeable and thorough. He also has an engaging bedside manner while remaining thoroughly professional.
It was my first time seeing him, and I went in for an annual. I had morning appointment, so I guess there was plenty of time, but he was kind and conversational. I need to get some immunization tests as a teacher, but didn't have the full list. Rather than ordering a random round of tests, and then having to go through the process again, Dr. L suggested waiting until I have the full list and then his office coordinator would schedule the tests immediately. I will definitely be seeing Dr. Leventhal again.
Excellent doctor who gives you pertinent information, is not an alarmist, and is very reassuring and helpful.
He's a kind man. Chatty & happy.
It's always a pleasure. I was welcomed warmly and seen by Dr. Leventhal after a very short wait.
Found Dr. Leventhal through ZocDoc, and was so impressed I made him my primary care physician.
Secretary is not accommodating.
Very helpful and friendly doctor
Always a pleasure.
Dr. Leventhal was wonderful. He was very attentive and thorough. I felt comfortable and cared for. I will definitely be going back.
Dr. Leventhal is friendly, welcoming and professional. Recommend him highly!
Dr. Leventhal was delightful. He has a fantastic bedside manner, and instantly made me feel comfortable and well taken care of. He was very thorough and didn't interrupt me or stop me halfway through discussing my current symptoms or pains. An absolutely great doctor to visit. The nurse was a bit brusque in comparison and could have been more friendly, but I spent the bulk of my time with Dr. Leventhal, who I cannot say enough nice things about. I highly recommend him.
He is a great doctor and seems like an all-around great guy. Very friendly and personable, he took the time to talk to me about more than just medical stuff. I am more than happy I made the switch to his office.
Really helpful and to the point. He was very quick and told me to call if I had any issues. Seemed like a doctor who cares about his patients. Highly recommend.
Excellent doctor. Great bedside manner. My only wish is that they took credit cards!
He is very good at his job. Knowledgeable, sensitive and respectful. He is direct, but not in a way that is unkind or offensive.
Felt very comfortable and loved talking to Dr leventhal he was very easy going and knowledgeable.
Great little office, Dr. Leventhal was very sweet and professional. He had great beside manner, and I didnt wait at all. As soon as I finished my paper work I was taken in.
Straightforward, easy to talk to, very professional, made me feel comfortable. Staff very accessible by phone and he will call you back if you ask him to
This was the most professional and helpful doctor visit I ever had .Thank you Dr. Leventhal.
Great, straight-forward PCP. Went for my annual check up and he was very engaged and friendly in discussions.
Excellent care provided by the doctor and his staff. Zero complaints.
My visit was a pleasant experience. Dr. Leventhal is the archetype of classic healthcare.
He's very experienced and knowledgeable. He makes you feel comfortable and addresses the issue based on the questions asked. He's friendly and respectable
No wait to see Dr. Levanthal. He was very personable and easy to talk to. Highly Recommended.
Took the time to get to know me, which I really appreciated! I felt like we had a relationship even after our short time together
Great doctor. Very pleasant, knowledgeable, and attentive.
The doctor seemed quite knowledgeable and was friendly, but I wondered whether he was padding his pockets in whatever ways he could. He ordered an overly extensive panel of bloods and urine (compared to other doctors) when I'm a young and healthy patient. The office was off-putting with a huge plasma-screen tv with advertising as well as multiple pamphlets spouting advertisements. The receptionist had little knowledge of how health-insurance works. She tried to pressure me to give her a check for the doctor's whole, unadjusted fee upfront, and she did not have an understanding of usual-and-customary-charges or deductibles. After she argued obdurately that if I wasn't going to give her the full fee, I should know what amount to give her, (though it's the doctor's job to contract a rate with the insurance provider,) she asked the doctor loudly enough so all the waiting-room could hear, "What do you do with a patient like this?" The doctor responded, "You do the right thing." I was mortified and I will never return.
Great but they only take cash
Very pleased. A good, down to earth, concerned doctor who likes his work.
He was very comforting, easy to talk to, professional and obviously knew what he was doing.
He was very friendly and knowledgable. I enjoyed my experience and he treated my symptoms effectively and efficiently.
Very professional. Funny and personable.
It was great just needs a technology update to make his process more efficient.
I liked that i didn't have to wait a long time to be seen. I also loved the fact that its a small office which is more quite and calm. I do not like a crowded clinic.
I found him to be very a ture professional, knowledgable, funny easy going. He is an old time hands on old school Doctor. Glad I found him.
Great Doctor, very comforting and addressed all my questions. Very personable
Dr. Leventhal met with me in his office first where he asked me questions and genuinely listened to what I had to say. He was fully present and caring. He didn't rush me, and I felt like I was really being listened to. I would DEFINITELY recommend Dr. Leventhal.
Excellent doctor. Very comforting and caring. Not a "business" doctor who is going to run the bill up unnecessarily. Good guy who knows what he is talking about.
has a sense of humor. Good doctor!
I liked Dr Leventhal. He was very personable, knowledgeable and patient.
Loved him! He was a very pleasant and professional physician. I went in for a simple referral and left feeling content with my new PCP.
He is amazing! I had a wonderful experience! He was both personable and knowledgable and super relaxing! I experienced no white-coat syndrome this visit!
Very professional, conversational, thorough. Very clearly knows his stuff and has the personality to make it work.
I was impressed. This is the doctor I have been looking for...thanks ZocDoc! I have recommended Dr. Leventhal to a friend and he had a positive experience as well.
I've been going to Dr. Leventhal for about 4 years now and he's easily the best doctor I've seen on a regular basis since I was 8 (now I'm 28). His bedside manner is amazing and he has made it a point throughout the years to get to know me as a person. I've referred several people to him, all of whom have had the same feedback. HIGHLY recommended.
Dr. Leventhal is a great listener with a patient and pleasant manner that inspires confidence. He is not eager to write a prescription for everything, which I appreciate.
We're leaving town soon and Dr Leventhal will be among the people I'll miss most.
Don't be fooled by his old-school charm. DR. Leventhall is a detail-oriented professional that answers questions thoroughly.
He is very caring
Excellent first time experience! I would definitely recommend Dr. Leventhal to others.
I was very pleased with this MD. Dr. Leventhal was thorough, personable, and in my opinion, highly competent. I never provide feedback (I'm lazy) but in this case it is definitely warranted. I highly recommend Dr. Leventhal.
Excellent doctor. Very caring and talks to you rather than getting you out the door as soon as possible.
Good doctor but no follow up was done to check in about test results.
I found the appointment to be cursory and quick, not thorough at all. Although this is my second appointment, I will likely find another doctor.
Very professional and nice doctor.
Dr. Leventhal is awesome. A old school type of non BS doctor with an excellent bedside manor. Some maybe put off by the decor of his practice which resembles the 1970's however I although a young person found great comfort in that. He is my PCP & has been for the pat year or so & I hope for many more to come.
Great doctor! I highly recommend dr. Leventhal.
I had an early appointment and was seen right away. He is very kind, knowledgable and attentive.
He is sweet and smart!
Very sweet and very knowledgeable. Took his time and was thorough. Lovely physician.
Very professional. I almost always pass out when I get blood taken. He kept me calm, told me stories and it worked like a charm. Great guy. Great doctor.
Dr. Leventhal was thorough, personable and has a great sense of humor. He was very efficient and kept my visit short, which was much appreciated, since I was feeling pretty sick. I'm happy to have him as a primary care physician!
Dr.Leventhal is a warm comapssionate physician who spends time with his patients .
Dr. Gerald H. Leventhal was very kind and was easy to talk to. I would use his offices again also give to my family members as a referral. Thank you!
In addition to being a good doctor, Gerald H. Leventhal has a lot of humor. Thank you!
I have been to Dr. Leventhal a number of times and have even brought my wife there now to be a patient. He has a great personality and I am very comfortable talking with him about my medical needs.
Visit was geat!
Happy I mad a great choice.
The wait time was quite lengthy (45 minutes), which made me regret showing up 10 minutes early to make sure I had time to fill out paperwork. Once I got to him though, Dr. Leventhal was kind and thorough and absolutely listened to what I was saying. I'll continue seeing him, though definitely will have to add an hour to however long I think the visit should take. Also - they don't take credit cards, which means I couldn't put the co-pay onto my Flex Spending card; I'll have to submit it manually... kind of annoying.
Great doctor, very personable and detailed. However the wait time was almost 45mins - but this is a general trend at practitioners.
He was an amazing doctor. Very personable and did a thorough check up.
I like how Dr. Leventhal went through all of my entire history of Lupus and asked questions my current doctor does not. His approach to lowering the my medicines made me feel more comfortable with him. He also gave me some background on Lupus I didn't know before.
He was extremely caring!
Dr Leventhal was absolutly wonderful!! He took his time both during the exam as well as his explanation as to what my symptoms were. He was kind, courteous and proffesional! I would highly reccomend him!
Very personable! I will definitely return.
An excellent doctor. You feel better just talkng to him.
He is very knowledgeable and I really enjoyed seeing him. It was a pleasure to go to the doctor with him, and going to the doctor is never a good thing!
Fantastic doc. Had an early appointment so walked right in with no wait. Excellent conversation and straightforward, down to earth guy. Would most certainly recommend to anyone looking for a General Practitioner.
Dr. Leventhal was a very kind man. I really felt like the doctor was taking care of me, instead of assistants. I was so happy he was able to do blood work right there in the office instead of going to a lab. He is definitely old school.
I was serviced very quickly and efficiently. Great doctor. I would highly recommend.
He's thorough and old school which is great.
Very patient,talks with you not at you and made my wife, who speaks english as a second language, feel very welcome and very well cared for.
I enjoyed my visit about as much as it's possible to enjoy a doctor's appointment. Good availability, convenient location and I was seen first thing. Dr. Leventhal has a pleasant way of explaining things, and he'll sit you down in his office to talk so you're only in the exam room for a short time.
Great guy! I will definitely return!
He's great. Very down-to-earth, good head on his shoulders, treats you like a human being and patient as opposed to a client or customer, which is not the case with a lot of NYC Upper East Side doctors. I'll definitely be going back to him.
He is always good, thorough and compassionate
My new favorite doctor.
One of the best doctors (if not the best) I've ever known. Highly recommended!
He was very down to earth and efficient!
Professional, knowledgeable, and great bedside manner.
Was quick, thorough, professional, kind and very helpful.
Dr. Leventhal was my pcp while I was living in the city, great bedside manner, good listener, would highly recommend to anyone without hesitation. Since I moved out of the city, I haven't found a PCP who is as good
Dr. Leventhal was wonderful. Very professional, courteous and knowledgeable. The front desk woman was incredibly rude and off-putting, however. I think he'd have a much better practice without her, but if you can suffer through her snideness and get into his office, you'll be fine from there.
My purpose for going to this appointment was for my annual physical. Dr. Leventhal's office is not the most modern, but I was perfectly fine with that. I always care more about the quality of the doctor. I arrived 15 minutes early to fill out my paperwork, and was seen in about a half hour even though I was the first patient of the day. He has one sole receptionist who handles phones, paperwork, etc. Dr. Leventhal does everything himself. First, I went in to sit with him and go over my medical history as well as my family's. He listened and at no point did I feel rushed. Then he did a thorough exam of my body, even checked my knee when I told him I had a partially torn ACL. Most other PCPs have only noted it, but have never gone so far to check it themselves. He does not have a nurse on staff, therefore he himself drew my blood. Throughout the entire time, Dr. Leventhal was extremely friendly - Perhaps the friendliest and most personable doctor that I have ever seen. He definitely took his time, chatting with me about his family and my interests and career, and made me feel at ease. For my purposes of an annual physical - this was great! For more serious scenarios, I am not sure if this doctor would demonstrate a sense of urgency, but I would go see him again.
I scheduled an appointment because I was sick and this office was conveniently located. Dr. Leventhal was very nice and efficient, however, the wait time was about 45 minutes and the front desk lady was not particularly codial. I am torn on whether I would come again. I did like the doctor, but the overall experience was not great.
I just switched jobs so I didn't have my new insurance card but the front desk woman was extremely rude and refused to speak to my insurance company or employer on the phone. She made me withdraw cash to pay for my visit upfront and wait 2 hours to see the doctor. The doctor was extremely professional, helpful and forced the front desk to give me back 75% of the money. I liked the doctor but would never come back because of the horrible front desk service.
very gentle and competent
Fantastic doctor. Dr. Leventhal made me feel instantly comfortable and was as gregarious as he was thorough. Can't overstate how good it was- is it unnatural to enjoy oneself in a doctor's office?
He's very old school, not medication-happy or into unnecessary tests, which I really appreciate. Friendly and personable. I would definitely go back.
As always great. Dr Leventhal is my primary care doctor and is always great. He is knowledgeable and thorough and treats everyone great.
Even though I arrived one hour late due to heavy traffic, Dr. Leventhal received me within 10 minutes. Dr. Leventhal is personable and professional. I would highly recommend him.
Dr. Leventhal is a bona fide old school doctor who actually percusses your abdomen when he gives you a physical. He's obviously drawing on decades of experience which is really reassuring. He cares about what the patient says, asks good questions, and gives the strong impression that he knows what he's doing. His only shortcoming is making a bit too much conversation that was off-topic, but he curtailed it immediately when appropriate.
Thorough, caring, personable... Well worth the wait!
Being new to NY I needed a PCP ASAP. I was able to get an appointment the morning of and he was fantastic. Friendly, inquisitive of my particulars, and refreshingly appropriate. He is my PCP for good now!
Dr. Leventhal made me feel at ease and hopeful about managing my chronic illness. He's smart, thoughtful, experienced and funny. I feel lucky to have found him!
Very nice (as usual) , was able to diagnose my problem right away.
Extremely pleased with Dr Leventhal, highly recommended.
What a nice experience for a change! Very thorough examination with a physical who has compassion and a great bedside manner. He spent An appropriate amount of time with Me and ordered bloodwork. Most of all, he listened to all of my concerns. Nice man!
It went well and I got everything I needed taken care of.
Well, I did have to wait an hour and a half in the waiting room which was a drag. Fortunately once I did meet Dr. Leventhal he lived up to all the positive reveiews here on zoc doc. He was engaged, humerous and thorough. He spent a good amount of time with me and I never felt rushed like I do most places now a days. He answered all my questions and happily made referrals for me for doctors for procedures that I needed to have done. That was really good because I feel that it will help me narrow down providers which is a godsend. I really felt like I had found the doctor I was looking for and now have someone I can call "my doctor". Priceless! I recommend him.
Waited about an extra 30 minutes after the time of my appointment but he is certainly worth the wait! Small, intimate office setting and everyone is friendly
I had full confidence in Dr. Leventhal from the moment I met him. He's all a patient should ask for. A rarity. Extensively experienced and knowledgeable, yet warm, compassionate, and attentive. He also has a wonderful sense of humor, which helped break down most of the fear I had built up on the way to my appointment :)
He was very knowledgable and caring. He offered great advice
I only went for a physical for employment, but I was seen right away and Dr. Leventhal was very nice and easy to communicate with after I left about tests that I needed done.
He was caring and thorough. A total find! Highly recommended.
I had a great experience with Dr. Leventhal. He makes you feel very comfortable instantly. He is extremely knowledgeable and very pleasant.
Great doctor with experience. Prepare your questions before hand though since you only allowed 15 min.
Old-school feel. Friendly, personable, hands-on (draws blood himself - saving me a separate trip to Quest Diagnostics is almost worth it alone). Listens to patient input. Definitely will stay with Dr. Leventhal.
The Doctor was excellent - very friendly, pleasant and I felt really comfortable I would recommend him definitely.
he makes you feel like he has known you your whole life.. The way doctors treated their patients like old-schoolback in the day..
A bit of a wait that day, but a good visit as usual.
Very kind. So professional and thorough.
Dr. Leventhal is very personable,he gave me valuable medical information and insightful recommendations after a comprehensive exam. I cant remember a more pleasant experience in a doctors office. I chose him because of his high ratings and proximity and now I understand why he has high ratings. Excellent Doctor.
Amazing Experience. I went this morning. No wait. A pleasure to deal with. Highly recommended.
It was great visiting Dr. Leventhal. He didn't waste any time, the appointment was quick and to the point. I'd definitly see him again.
As always - he's a pleasure to see, very straight to the point, and works to get answers quickly.
Dr. Leventhal was great. Excellent bedside manner - bit of humor, friendly, curious about me. Saw me maybe 10 minutes after my scheduled time, not bad!
I was one of the first patients to arrive this morning. He spend alot of time with me and did not rush at all for the next patient. Nice person, attentive. I would recommend him.
He seems to be a thorough, straight-forward physician who showed a genuine concern for me as a first time patient. He explained what he was doing and why in a friendly manner with a dash of humor.
very knowledgeable, took the time to explain tings. Highly recommend.
Dr. Leventhal has a lovely little office on Park Avenue where he actually does everything himself including the EKG, taking blood, etc. He was extremely friendly, kind, easy to talk to and concerned about me throughout. I am thrilled to have found him.
The office staff was sensational. VERY friendly and efficient. The doctor was knowledgeable and went the extra mile to find added information for me.
Very kind and understanding physician. Addressed all of my questions and concerns. I would highly recommend Dr. Leventhal.
An excellent doctor experience. Dr. Leventhal took the time to listen to my family history, speak to me about what I should be on the lookout for, and do a quick but thorough examination. I would highly recommend him, but would say to expect to be seen a little later than the actual appointment time.
Kind, sympothetic, professional
Dr. Leventhal is very nice and seemed very knowledgeable. My appointment was at 10 and wasn't seen until 10:30, but was worth the wait.
He was OK, but waited a pretty long time
Visited for a physical due to recommendations here and was very pleased. Seems knowledgeable and is very willing to listen to concerns. I will definitely be returning in the future.
Decided to visit dr. leventhal based on the reviews here. he's exactly as described.
Very personable, really takes the time to listen.
Dr. Leventhal is a very genuine physician. I found his bedside manner fantastic. His receptionist was not as welcoming... but physicians should not be judged too harshly on their support staff.
The comments that were previously shared on Dr. Leventhal were so kind...and I must say the were spot-on. I had to find a doc in a pinch due to an illness right before traveling for the holidays. He was the kindest, most gentle doctor I've seen in AGES and is just a good person in addition to very knowledgeable. He took time to have a true conversation as well...I will most likely request to see him again.
he's a great doctor. he knew my name and really seemed interested in my health and well-being. he took time with me and did everything himself.
If you remember as a kid the doctor who knew you and your family and really CARED, Dr Leventhal is the one.. He treats you as if he has treated you your whole life. He is old school medicine, no phony here.. I recommend him to anyone who wants a REAL AND CARING DOCTOR..
Excellent experience. Highly competent, and also seems to have excellent priorities and judgment.
Easier to get the appointment via Zoc Doc, as opposed to via phone.
Routine physical- quick and easy, thorough and efficient
Wonderful experience. Would reco to anyone.
Incredibly efficient, great office staff and amazing bedside manner. Made a routine check-up a quick, painless experience.
very good guy, seemed to be a good m.d. but who knows.
