Dr. Maria New is considered to be the leading expert in this field. She is at Cornell University. I have done a lot of research, and the leading research has been conducted at New York Hospital, under Dr. New's supervision. She has an attending named Dr. Maria Vogiatzi and she is great. They are very good about discussing things with you on the phone, working with your endocrinologist, and helping you make decisions for your child. Dr. New was featured on 20/20, and truly is on the cutting edge of CAH research. Good Luck. The number is 212-746-3462 or 212-746-3483.
