I have left messages for the nurse and either i don't get a call back or it was the next day. My child is on daily meds and to get a refill each month is like pulling teeth. But just to clarify the problem does NOT lay on DR. Hammer she is a terrific doctor and when you FINALLY get to see her she does spend a lot of time with you and does answer all of your questions. I have never had a problem with her requesting referrals. She actually goes beyond to make sure there isn't something else wrong.
