(Select your rating)
I believe Dr. Cosmi is THE BEST! He is a sensitive, caring, knowledgeable, current doctor and a spectacular human being. He makes me feel at ease and NEVER rushes me. He answers ALL my questions, and there are always many. Every single person I have recommended him too feels the same way. My husband and I are thrilled to have found his practice. They are outstanding doctors.
