Who We Are

At Antietam Pediatric and Adolescent Care, our primary goal is to ensure healthier lifestyles for the pediatric and adolescent populations. Responding to the needs of patients and their families is our highest priority. We continue to meet this standard with our trained professional staff. We work closely with Meritus Health System, area physicians, and the community to develop our services in a way that can best provide care for children in years to come.

Antietam Pediatric and Adolescent Care, located in Hagerstown, MD, was established in 1998. The practice is operated by Kristina A. Athey, M.D., Leon D. Weaver, Jr., M.D., all board-certified in pediatrics, and Karen Barb, CRNP. We also have three other providers – Alicia Isom, D.O., Danielle Reynolds, MD, and Nora Katerji, MD. We hope you choose our family to take care of yours.
