She is one of the best doctors I have ever seen. She’s smart, listens, explains and allows me plenty of time to ask questions. I can’t stand those chronic malcontents that love to malign good people. This doc is A-one tops!!

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 or let me talk and just told me 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 I simply needed a round of antibiotics.

I have been a patient of Dr Diane Williams going on 14 years for a total of 4 colonoscopies. After watching my father die of colon cancer, I cannot begin to fully appreciate the piece of mind her care provides. She is kind and professional and excels in providing the very best in care. When you meet her in person you know she loves people as well as what she does. I am so grateful for her and the care she provides!

I found her after having been to another clinic where I wasn't listened to. She took the time to really listen to me and came up with a plan that is right for me. Her caring and concern was genuine and greatly appreciated.
