The reviews listed below were collected independently of Children's Medical Group through rater8. Each review represents an authentic and verified patient experience.
Dr. Marcus was very kind and caring, but also very direct, which was exactly what we needed. She took the time to calm and follow up later that evening, and reassured us we were on the right path. Highly recommend!

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.

I’m a new mom and have only met with Dr. Marcus one time so far, but was blown away by her care, attention, and practicality in advice she gave us. As new parents, this was so encouraging.

Dr Marcus is awesome. She is great at answering questions in a way that is easily understandable and comforting to parents. Very genuine and empathetic in the way she addresses our concerns.
