“To put it succinctly you won’t find a better gastroenterologist in Los Angeles. I’ve had issues for years and have been to several other gastros until I found Dr. Tabib.

He treated me for my ongoing problems and insisted on a colonoscopy, which unfortunately for me revealed cancer. I simply adore him and his assistant Tammy. Thank you Dr. Tabib for saving my life. Please everyone, get your colonoscopy!”

- Deborah P


“I did have to wait about 50 minutes but once I got in to see him he gave me his undivided attention and wasn’t rushed. He asked me a lot of questions and fully explained his thoughts and work up to me so that I could easily understand it. His assistant Tammie is awesome and I would highly recommend Dr. Tabib to anyone who needs a caring and thorough doctor.”

- Kristi N.


“My family has a history of colon cancer and Dr Tabib has been our trusted doctor for years. When I turned 50 and needed my first colonoscopy I went to Dr Tabib (just like my father and brothers). He does a great job of preparing you for the procedure and makes it as easy as possible. The office staff is great with scheduling appointments and following up with you after a visit to the office. I trust Dr Tabib with my colon cancer prevention and you should too.”
