Patient Reviews
Jan 27, 2023
Dr. Marcu took great interest in finding the source of my GI bleeding, even when it was not evident after four different procedures. Dr. Marcu went the extra mile, even calling me personally to let me know when he did find the source of the bleeding. I was, however, extremely disappointed to hear that he would have to refer me to another specialist to treat the cause. I highly recommend Dr. Marcu to anyone experiencing any GI issues.
