"I have been a patient of Dr Phelan for about 10 years. He is personally very good. However, the endocrinology practice has several major problems."

— WebMD Care

"The receptionist took our information and told us they would call us when they could see her. We waited until 11:00 and I called again. Was put on hold and then hung up on."
