Extremely professional and very thorough. I have been dealing with issues with numerous Gastro doctors with no success nor any possible solutions. This doctor sat down with me for over 30 minutes went through all the previous doctors test and results and what they had prescribed or tried to do and he came up with a detailed clear game plan. I left there feeling very confident that I finally found a qualified and caring doctor.

Dr. George was pleasant, professional and welcoming on my first visit to his office. He provided detailed information on gastrointestinal topics and took his time to address the concerns. His office was spacious, clean and neat and offered a peaceful atmosphere. He was attentive and listened carefully, then provided the opportunity to ask questions for clarity. I would recommend him to new patients in a heartbeat and understand why he is a commodity in his field.
