There is no question that Dr. Sai is one of the top physicians I have ever been treated by. He is not only a great doctor he is a wonderful person. If you are looking for a G.I. specialist, I would highly recommend you consulting with him. Dr. Sai saved my life and forever changed me as a person. Respectfully, John G.

Dr Baker has wonderful bedside manner. His staff and Dr. Baker made us feel comfortable. He listened to our sons medical history attentively. Gave us great feedback and a great start to our sons line of care with him as his new Gastroenterologist! This is is GOLD to us so we do not mind the 50 min drive to see him. ❤️ thank you!

Dr. Brown LITERALLY saved my son's life! After 4 years of surgeries & hospitalizations, our son is finally healthy and growing and back to a "new normal"! He endured so much more than any person should ever endure, but we were so blessed that God brought Dr. Brown into our lives! Our God was the ultimate healer, and He used Dr. Brown in a mighty way! Thank you Dr. Brown (& staff) for all you have done for Johnny & our family!
