excellent professional medical service
I like Dr. Berestrand, overall the process was frustration free, the location is good and I was able to get a same-day appointment.
Dr. Williams is easy to speak with and at no point do I feel "embarrassed" to express my symptoms.
He was very pleasant and i didnt feel rushed at all.
Dr. Williams is one of the best doctors I have seen. He is thorough and caring to the patients individual needs and questions. He also addresses questions directly and doesn’t evade or beat around the bush.
It was a long wait but it was worth it.
Dr. Williams was super respectful, patient, and thorough.
It was a great visit, doctor Williams was great.
Wow! For as long as I live in New York Dr. Williams will be my PCP. Talk about good vibes, connecting with patients, compassion, expertise, experience, and professionalism. Hands down the best experience I've had with a doctor as an adult. Also very impressed with the Mount Sinai system in general.
Dr. Williams was extremely pleasant, thorough and explained things well. I felt very confident that I was in good hands!
My visit with Dr. Williams, he was very professional and his bedside manner was excellent. I would recommended Dr. Williams to my family and friends.
Dr. Williams is a kind, gentle, wise and thoughtful doctor two whom I'll certainly be returning. Through no fault of his, I had to wait more than an hour beyond my scheduled appointment time to see him -- but it was well worth the wait, and I'll certainly be back!
Dr. Williams was very thorough in assessing me, and provided rational and comprehensive explanations in a patient and courteous manner. His professionalism, knowledge, and as well as his concern for getting to the heart of my condition impressed me and gave me the optimism that whatever I have can be diagnosed and (hopefully) treated. If there is a doctor who is smart and attentive enough to get to the roof of a health problem that seems as "mysterious" as what I have - he seems to be that doctor!
Great guy and very professional and timely.
My visit with ZocDoc was very informal. He is attentive, ask tons of questions, listens to you, and gives valuable feedback. He is gentle and shows concern in your health, unlike some doctors just getting the job done. I would definitely recommend Dr. Williams. He also does pediatrics!
Berestrand Williams is by far the best MD I have ever had. He is super knowledgeable and his manners are superb.
Being a healthcare professional myself, Dr. Williams had the highest level of professionalism and same level of personal touch. He expressed concern, listened to my issues and made sound clinical judgements. I highly recommend this practice.
He didn't look into all the things I requested, not sure why but from a patient standpoint, if they ask them to look into it they should.
Outstanding, knowledgeable and very attentive doctor! Would recommend to anyone. He was a pleasure to meet with!
I love this doctor! I am 36 and this is my first time saying this about a General Physician. He is caring and actually remembers his patients. Kudos!
Very professional and answered all of my questions. I also had to meet with two nurses, one of them was spot on, and the other was kind of not all together. Aside from that, had a good experience.
Great practitioner, takes the time to fully explain the diagnosis. I only wish the waiting time was not so long (40 min despite appointment)..
Visit fine - super long wait in waiting room (over an hour), and then very long wait in exam room.
Dr. Williams was thorough and kind. Just what I want in a PCP.
Dr. Williams is a class act. This was only my 2nd visit, but I knew from my first time that he was a keeper. I am impressed by Dr. Williams - he is both respectful and knowledgeable. I find him extremely easy to talk to, he listens well, and best of all, he is not a "drug or test pusher." It is difficult to find caring, smart, intelligent, and respectful doctors who also have a friendly disposition. I'm so happy to have found Dr. Williams!
I waited 45 minutes to be seen and didn't see the doctor for over an hour. When he came in, he informed me that a student would be taking some notes. The student was kind, but asked me questions for another 15 - 20 minutes. Then the doctor finally saw me and the student spent another 10 minutes going through his notes before the doctor even gave me an exam. I'm completely fine with teaching hospitals, but you need to be respectful of people's time. The student could have interviewed me in front of the doctor and saved half the time, especially when they knew they were already late for the appointment.
Dr. Williams was courteous, attentive, and friendly. He received a call about another patient during our visit and he was polite in refocusing his attention on my appointment. Truly a genuinely caring physician.
I liked Dr Williams and will go back again
Wonderful visit, very thorough and thoughtful.
The doctor was very caring as was the staff. It was my first appointment will definitely choose him as my primary care doctor.
Probably the best doctor I've ever had.
Dr. Williams has such a warm and kind personality. My son was extremely cheery and compliant for him, which has not been the case with his previous pediatricians.
From the front desk staff to the medical assistant and finally the doctor, everyone was super friendly and professional. I had zero wait time as well. Dr. Williams was very kind and professional, answered all my questions and very patient. I have been looking for a pcp for quite some time and am glad I found Dr. Williams.
Dr Williams is great. So glad he's my PCP. Very friendly and courteous. He is extremely patient with all my questions. Very responsive with any needs.
Dr. Williams is an excellent Doctor. His bedside manner is impeccable. He discusses everything thoroughly. He takes his time with questions. Very knowledgeable of all aspects of healthcare Very proactive with preventative care. Checks to make sure that I am taking care of the other aspects of my life outside of general health
Dr. Williams and his staff were fantastic. The reception area was a different matter, unfortunately. The admin/receptionist were unprofessional, coarse, even rude. I wasn't greeted when I arrived and was abruptly asked to sit and to wait to be checked in - in a relatively empty/low traffic reception area. This experience will not deter me from remaining w/Dr. Williams in the slightest, however, I was somewhat taken aback by this treatment.
I didn't have to wait more than five minutes to see the first physician. After my vitals were checked, the wait for the doctor was no more than five minutes. I had a positive and pleasurable experience and felt comfortable throughout my entire visit.
Very knowledgeable and nice, he took the time to answer my questions and had a straigh diagnosis for the rash my baby had. I am very pleased with this doctor
Dr. Williams is very straight forward and great at explaining all the medical terminology to his patients.
Dr. Williams was very thorough and patient with my questions. He gave great explanations and spent a lot of time with me. I would highly recommend him!
Impressively patient and thorough. The entire team was so fast I couldn't finish my paperwork before being done with my visit.
He clearly likes practicing medicine and it showed as he was thoughtful, articulate and engaging. He did a thorough medical exam, history, etc. Very impressed and encouraging!
Dr williams was kind and efficient and knowledgable, completely engaged with me and i felt like i was his entire focus.
Very knowledgeable and incredibly efficient, hard to ever say it but would almost say I enjoyed my doctor appointment
Loved him, so personable and easy going. Def going again.
I arrived 15 minutes early to my appointment to fill out paperwork. I ended up waiting more than an hour after my appointment time to be seen by the doctor. I had to leave to get back to work. The front desk and doctoral student who spoke to me were nice but I would not recommend seeing this doctor.
professional, helpful, very knowledgable.
Berestrand was attentive and helpful. We discussed a number of things as it was my first visit and he was knowledgeable, straightforward, and I never rushed. Great experience, highly recommended.
Everyone was very pleasant and professional. Thanks!
Dr. Williams was very kind, thorough, and attentive during my visit. He took time to listen to me about my medical history and just to chat. He did not seem like he was in a rush or distracted, which is a nice change of pace from many physicians these days.
My office visit was very smooth with Dr. Williams. The offices were nice and there was minimal wait time. I went in for an annual physical and will definitely be returning next year.
I thought Dr. Williams was thorough and great at listening. He provide alternatives that my specialists did not suggest. I chose him from ZocDoc based on the recommendations and ratings. Thank you! The feedback was right.
Great visit. Dr. Williams was very informative and friendly. Will certainly be returning!
Been seeing Dr Williams many years.. just terrific!
He was as good the second time as the first.
Dr WIlliams is fantastic! He is a medical detective - and takes time to listen, explain the causes of symptoms and diseases as well as providing safe, natural treatments. Highly recommended!
Dr. Williams has an excellent bedside manner. He listens patiently and lets you talk through what's troubling you before offering his professional opinion and advice. As if that wasn't enough, he's got a good sense of humor as well. I won't be looking anywhere else for primary care, so long as my coverage stays the same.
First time patient. 10 minutes of first time patient paperwork, and then promptly seen by nurse, and promptly seen by Dr Williams. He was thorough and perhaps the least rushed doctor I've experienced.
Dr. Williams made my visit pleasant and comfortable. He was professional and informative too! You can tell immediately Dr. Williams genuinely cares for his patients and takes the time to listen to your concerns. I'm extremely thankful I found an awesome Primary Care Physician I can trust! Thanks Doc!
A wonderful experience . Dr Williams is thoughtful, patient and assuaged all of my concerns and fears with calm and common sense.
He is a Genius Physician. Compassionate and extremely knowledgeable! Jacqui M.
Terrific office, care and attention. Very personable and knowledgeable. Happy to be in his care.
very kind, listened to what i had to say, had patience.
Dr. Williams is great. Helpful and knowledgeable and took the time to discuss my options with me.
I loved my first visit with Dr. Williams! I decided to give him a try based on his ZocDoc reviews and I now see why people love him. He's extremely personable, a great listener and TAKES HIS TIME, which is an extreme rarity for doctors in NYC. I honestly look forward to my next appointment with him. Would highly recommend.
I went in for a routine visit. Normally if they see your alright and young they tell you everything is ok. It's probably stress. But he listened very patiently to everything I said and asked a lot of questions. Very attentive to detail.
Dr. Williams was extremely thorough and professional in his history taking. The medical student who joined him in the physical exam was also very polite. Dr. Williams was very clear about what kinds of tests I would be needing and explained why certain tests he opted out on would be extraneous. The entire staff made me feel very comfortable to be there. Despite the wait to be seen once in the exam room, I will definitely be returning for the exceptionally attentive and cordial care Dr. Williams and the staff at his office provided.
He was very nice, and attentive. Listened to everything that I had to say, and gave great recommendations on next steps. Looking forward to working with him for a time to come!
Thorough and considerate. Listened to what I said and what were my concerns.
overall very professional! Very happy to have him be my primary doctor!
Berestrand W. Williams, MD is one of the best doctors I know. I've been going to him for many years. He takes his time to ask you questions to better diagnose your symptom.
Very straight forward. Assessed my medical dilemmas instantaneously.
Fantastic just a super super long wait to be seen
Very happy with it, and all their help.
The best doctor I've had in my entire adult life to date. He recently moved from one location which was more conveniently to locate to another facility somewhat not as far but I will continue to be a loyal patient as long as Dr. Williams remain my Physician. I should also include that both Mt. Sinai/ Beth Israel Facilities were very clean, and nice with an amazing staff.
Dr. Williams was an incredibly thoughtful doctor. He took the time to listen to me and my symptoms. He engaged in friendly conversation and had an overwhelmingly calming nature. Definitely recommend!
Dr Williams is amazing. Excellent bedside manner, very knowledgable, takes his time to answers questions. Wonderful experience. Everyone should transfer to his care. Great doctor!
The environment of this location as compared to the Center for Health and Healing is very sterile and unappealing..
I know him for years. Would never go elsewhere.
Dr Williams was very clear in explaining the issues and about next steps. I also appreciated and valued his manner and overall friendliness.

Very patient and efficient. Will go back!
Dr. Williams was very thorough during my first visit with him. He made me feel listened to and made sure to answer all of my questions. I look forward to seeing him again in the future!
It was evident right away that Dr. Williams processes encyclopedic medical knowledge, but he was also able to explain it all with such clarity and respect for me as a layman patient. I have undoubtedly found my new primary care physician!
Dr. Williams was great! He was knowledgeable, kind, had a great bedside manner, and took time and care in addressing my healthcare concerns.
New patient, very positive & friendly, listened (most important), Willing to explain & give suggestions. Very nice staff as well.
GREAT DOCTOR AND GREAT STAFF!
My first visit with Dr. Williams was great. I needed a routine physical, and I had a few questions. He answered my questions and completed my exam in a very straight-forward and respectful manner.
The BEST experience I ever had in a medical facility. NO waiting time, staff fun and very nice. I didn't feel the rush at all. Doc was AMAZING, nice, attentive, caring. He understood perfectly my situation, my choices and helped me out through the process. I really wish people could learn from this facility how to conduct a medical institute. Smile is the best cure for the soul.
This was my first time at this office and Dr. Williams was very thorough and was aware about LGBT issues and was very professional.
Dr. Williams was very professional and friendly. He was very knowledgeable and legitimately concerned with my overall well-being, not just with diagnosis and prescription.
The doctor was wonderful. He explained everything, took very thorough test and followed up on my results with prescriptions for my next recommended test. Its nice to not feel like a number when you visit a doctor.
Dr. Williams has been my physician for the last 10 years. He is thorough and very knowledgeable. I trust him "with my life." I feel as though he cares about the quality of my day-to-day health.
really nice guy, attentive, detailed , today was my first visit, so far so good....
One of the rare instances nowadays of a doctor who actually spends time with the patient, doesn't rush in and out and genuinely has the patient's best interest in mind. Highly recommended!
Dr. Williams was extremely helpful and informative. I would recommend him to anyone.
Dr. Williams is an excellent doctor and a fine man.
