The care I received from this practice is the best care I have ever received in my life. The doctors reviewed my medication that I have been taking for 25 years and updated the medication and changed their dosage. They asked questions, listened to answers and came up with an ongoing plan or my health.

She often runs late but the quality of the visit with her is so great, that I don't mind at all. She is so smart and really listens, caring and has really helped me with thyroid and hormone issues.

Dr. Rettinger was the best MD I have encountered. One of the few to take the time to listen to a full medical history. She is a great communicator, knows when to listen and when to answer with her knowledgeable skills. She brings out the best in medicine with her compassionate, patient and enthusiastic personality. Her detailed and comprehensive use of intelligence and experience provided a comforting feel that she will be able to her patients to the ultimate and fullest.I am so fortunate to be able to have her be my physician.
