Dr Fiman has been treating me for many years. I am so fortunate that I found him. He's the greatest! I am especially thankful to the care he has given my daughter who was 15 when she started seeing him for Crohn's Disease. She is now 22 and has been in remission for two years all thanks to Dr Fiman. Highly recommend him for GI needs

(1) office overcharged me for consult; took 8 mths to obtain refund (2) Colonoscopy Report had 2 errors; took multiple calls to obtain corrected report (3) despite dr/facility being in-network and UHC confirming 2x procedure covered 100%, Fiman/facility used out-of-network providers for which I was billed $1,500+. Never would I recommend Fiman/his admin facilities/staff. Plenty of good Gastroenterologists who have efficient office staff and who use in-network providers.

Dr. Fiman has been my doctor for over 5 years. He is excellent and very up-to-date on the latest research for Crohn's Disease and other digestive tract issues. I moved from the Houston area and I travel 3 hours to come back to see him. Having a competent, knowledgeable, and personable physician is well worth the drive. I appreciate his frankness in explaining my illness in terms I can understand. I would highly recommend him to anyone searching to find the best doctor in his field.

I have never seen a GI before. He was friendly and made me feel at ease talking about embarrassing issues. I know he hears stuff like this all the time, but I was mortified to discuss my stool - frequency, consistency, etc...Dr Fiman and his staff are professionals. They make you feel like every question is valid. He took his time to address all my cnocerns
