The best! So thrilled we made the switch to CMG Decatur. The staff are wonderful, responsive, and there are no admin headaches as we’ve had with another large popular Atlanta pediatrician’s office.
Dr. Marcus and her team are WONDERFUL with my girls and my daughters love every chance they get to go to the doctor.
My only complaint is one of the phlebotomists we’ve had in multiple occasions is not great with littles and I’d prefer she does not work with anyone under 7.
