Dr. Rettinger was thorough, warm, and validating in all the right ways. I was worried my concerns might be dismissed as I had heard that many endocrinologists are afraid of diagnosing possible PCOS but she was very adept at discussing differential diagnoses, ordering the right bloodwork and tests, and open to taking seriously PCOS.
