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.

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
