Dr. Andrew Warner

Originally from the Cockeysville/Timonium area, Dr. Warner joined the Maryland Medical First team in 2026. After finishing medical school at Marian University College of Osteopathic Medicine in Indianapolis, IN, he went on to complete residency training here in Baltimore through MedStar’s Internal Medicine Residency Program, where he developed a strong foundation in comprehensive, holistic care.

Dr. Warner’s medical interests include advanced care planning, primary prevention, as well as addiction medicine, with a focus on supporting patients and families through complex medical and life transitions with compassion and respect. Outside of medicine, he enjoys all types of fishing, spending time on Maryland’s Eastern Shore with his family, and is an avid fan of the Baltimore Ravens and Orioles. As a Baltimore native, he is excited to join Maryland Medical First and treat patients in his hometown community.
