Dr. Marcus enjoys all aspects of pediatric care, and she is especially passionate about discussing child development and preventative medicine at well visits. Dr. Marcus always makes it a priority to get to know her patients and their families on a more personal level.

In her free time, Dr. Marcus enjoys spending time with her husband and two teenage daughters. She also enjoys running, reading, baking, traveling, and being with family and friends. Dr. Marcus has been practicing in the Decatur area for the majority of her career and is so happy to be part of the CMG family.
