My wife stated that she got great service from all the medical professionals she dealt with. Unfortunately our dealings with one individual not involved in the medical process (front desk) tainted the review. This is a makeup review to account for that.

I had to get a screening colonoscopy and moved from SF to Marin recently and ended up here because it was close and convenient. I’ve read some somewhat so so reviews online so wasn’t sure what to expect and I had a super pleasant experience. Dr. Sharma was great, the CRNA was great, and the whole thing was fast and painless. I was super anxious and they quelled all my fears and made me as comfortable as possible. Scheduling and the whole prep process was easy as well. Not sure what the deal is with any of the negative reviews, but I wanted to come on here and write this one since I feel like people often only write these kinds reviews when they have something negative to say.
