Dr. Rettinger is incredibly knowledgeable, takes time to understand and explain things well and determine the best course of treatment. She is kind, thorough and makes sure you have all of your questions answered. One of my best experiences with a doctor despite it being online.

Dr Rettinger is the most excellent endocrinologist/doctor I have ever dealt with. She is a partner in my health care, willing to discuss and listen. She is easy to talk to and very knowledgable. I feel very lucky to have found her and hope to have her as my doctor for a long time to come.
