Dr.Williams is a wonderful doctor and very attentive to his patient's needs. While this visit I waited quite a while to be seen by the doctor, I was ok as this doctor is very good at what he does and actually LISTENS to his patients and takes the time to figure out the best plan of care for his patients. I would recommend Dr.Williams to anyone.

I am very grateful to have Dr. Williams as my doctor. He is always available if I have problems with my medications. Even when I leave messages for him. He always responds to my messages.

Dr. Williams is a thoughtful caring and intelligent physician. I wish I could have him as my neurologists but he specialises in the EMG studies but gives recommendations that are helpful. I have seen him twice and will continue as my disease progresses

I've seen several IHC neurologists and had a horrible inpatient experience 11 years ago. I was NOT a fan of returning to your establishment but Dr. Williams doesn't think he's a God and he also has sense enough to listen to the lived experience of his patients. Give him a raise in my opinion.

Dr. Williams is truly phenomenal. I rarely feel so cared for, listened to, and helped by a physician, especially a specialist. In many ways he has changed by life through his help with my post-concussion symptoms. I couldn't recommend him highly enough!

I was VERY impressed with Dr.Williams and how knowledgeable he was. He went through all options available and explained potential reasons why I was having the symptoms I was having. He is a physician that ACTUALLY LISTENS to his patients. I highly recommend him!

The doctor was also very kind and considerate in listening to my concerns and the events which I believe may have started my condition. He explained what tests he was going to perform and he made sure we understood what the tests consisted of and explained how each would work.
