Dr.Rahbar is a meticulous doctor. During our first appointment he took all the time necessary to go through my history and current symptoms with precision to best diagnose me with an underlying cause no other doctor may have thought to verify. The healing process is a long one and he has been there checking in and modifying my treatment plan along the way. Thank you Dr. Rahbar

Simply put, Dr. Rahbar saved my life. After three excruciatingly painful fistula surgeries, I was feeling depressed and hopeless. No one could help me heal. The surgeons just wanted to cut and stitch. Meantime, I had a 3 year old and a 6 month old that I needed to take care of and a demanding full time job. There were days I was in so much pain from the surgeries, I would pass out. I finally decided to take my health into my own hands. I think it was a miracle that I met Dr. Rahbar. He is caring, kind, and genuinely wants to understand and help his patients. He’s unbelievably responsive and even called me the day after my fourth surgery to check on me! He helped me understand the importance of supplements that were “right” for my body. Under his care and supervision, I was finally able to heal. He is the definition of a healer.

Dr Rahbar is one of the smartest doctors I have ever met(I have a doctorate in engineering myself) he has mastered both traditional medical science and herbal therapies which is really hard to find, on top of that he really cares and listens to patient carefully, he is very kind and caring in addition to be a top notch GI dr, he tailors his approach in the most optimum way and his success is not random. His staff are very helpful specially Andria. Will continue to consult his practice.

I've been struggling to figure out what my symptoms were for over a year. I decided to give LA Integrative Gastro a shot, since doctors didn't want to hear me out. Dr. Rahbar gave me 2 hours of his time and asked all of his questions and from my labs found out what I had. He provided me with a comprehensive plan for getting me healthy again. He's very attentive and listens to his patients. The staff is also amazing. Couldn't have asked for a better outcome with his team.
