Verified Patient Reviews
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 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.
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.
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.

Been seeing Dr Williams many years.. just terrific!
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.
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!
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!

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.
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!

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.

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.
