I really can't recommend the Center for GI Health whatsoever. Went there due to ongoing (over 6 months) stomach pain after getting a CT scan and ultrasound. Dr. Markos recommended an endoscopy. This procedure was done, he saw me after the procedure and said it showed nothing, and that was it. No follow-up (except to tell me I owed them a co-pay), no suggestions, nothing. Tried to get my report (which was never sent to me) and was put on hold for 15 MINUTES. Still in pain with no ideas offered!

Dr. Markos is a very uniquely kind and special doctor, he came highly recommended to me from my friend. I have IBS and he helped me manage my IBS without the need for scoping, but with dietary and lifestyle changes. I really felt that he always cared about me and listened to me. He is a very special doctor and I miss his conservative and caring ways, having moved to Philadelphia where everyone wants to order unnecessary tests prematurely. Dr. Markos actually listens and treated me very well!

I was scoped by Dr. Marcos in 2014 as a family member told me they were diagnosed with the hereditary condition known as Barrett's esophagus. Not only was I diagnosed as having Barrett's, remarkably, Dr. Marcos also identified a considerable lesion on my small intestine. Fortunately the lesion was not cancerous, but would have become cancerous within 1-2 years. Dr. Marcos referred me doctors to deal with the condition. I was operated on, the lesion was removed, and I am fully recovered!

Dr. Markos is a very kind and caring doctor. He takes the time to get to know his patients and listens to all concerns. He is really thorough and does a great job explaining his thoughts and next steps. One of the only doctors I have seen who sits you down in his office to chat after your exam.
