Dr. Williams was very attentive to my questions. Knowledgeable. Covered everything. I have had this procedure before with her and she was great. My husband also see her. I have recommended her to many friends and relative. Her staff have been on top of everything and in the past very good care while there.

Awesome doctor! Smart, caring, competent, the best. She was very available to talk with me, but of course, schedule an appointment to do so! Her time and expertise is valuable.

My experience with Dr Williams was great until I had questions after my procedure. She would not return my calls and I was told the only way to speak with her was to make an appointment. Trying to get information from staff is very difficult. I went into my procedure thinking it was covered and was told so but then I received a huge bill and no one at the clinic will discuss it with me. I would be very hesitant to recommend this location.

If you want a doctor who has seen everything there is to know about your guts and will assuage your fears about your intestinal health, she's just perfect. I have the blood work for an autoimmune disease, and she knew all about what to test and look for and I'm glad that I had her year's of experience and to review my health. She's also very pleasant and, for all the afore stated reasons, you should book with her.

On my first visit she ordered a barrage of tests to eliminate or verify causes, told me to cut out artificial sugar and come back in 3 months. I went back today with my symptoms not improved at all. She told me I had IBS but she wanted to talk about my weight. For about 45 minutes she told me I needed to lose weight. Told me to see a dietician and come back in 6 months. She offered no help with the IBS. I will see the dietician but I won't be back to Dr Williams. What a waste of time.

Have been a patient of Dr. Williams for many years. To put it simply, she has saved my life by diagnosing and treating Barrett's. She is the best!

The worst dr ever. Misdiagnosed me with IBS, mostly because I have chronic migraines and I am in my 20s. I came in 6 months later, barely able to function (couldn't eat/get out of bed) I had 3 red flag symptoms that indicated it was not ibs. But she didn't even listen to me gave me an unnecessary colonoscopy and just told it was all in my head and to see a therapist. Therapist told me it definitely was not in my head and to find a new dr. Turned out to be SIBO and simply needed antibiotics

Dr Williams has been my physician for many years. She is highly professional, current with her practice, and personable. My mother died of colon cancer, so my:colon care is very important to me.

I do not feel like I am treated like a person by her. Most of the times I have seen her, I have been in tears right afterward. She takes no time to answer questions and rushes right through our appointments. She may know her stuff (I don't know because she takes no time explaining anything) but she doesn't come off as a caring professional.

I had the best experience with my colonoscopy with Dr. Williams. The entire staff was great, the process was smooth and organized and I was completely comfortable the entire time. Dr. Williams was friendly, competent and gentle. Would not hesitate to recommend this doctor and this clinic to anyone. It's first rate.
