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 impressedme 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!

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!

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 extremelyeasy 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 another15 - 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 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 waitto 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.
