I have been to a couple of other GIs over the past 10 years who could not figure out my issues and just summed everything up to IBS without doing any further testing. Dr. Marcu did further testing and found out that I have Celiac disease which is what has been causing my issues for the last 10 years. He was very thorough with all of his explanations and even called me personally with my test results. I could not recommend a better doctor to anyone.

Dr. Marcu was the worst doctor I've ever dealt with. He never let me finish a question before cutting me off and answering it. He called my mother antagonistic for showing concern about my disease. There was absolutely no "bedside manner" shown which should be given to a young girl learning she has a lifelong disease. I never received phone calls from the office about biopsy results, blood tests, or an MRI. He implied that I was lying when I stated I didn't get the calls. HIGHLY DO NOT RECOMMEND
