Dr. Tim Horgan is a board-certified general pediatrician who treats children of all ages, from newborns to age 18. A native of Atlanta, Georgia, Dr. Horgan earned his Doctorate of Osteopathic Medicine from Philadelphia College of Osteopathic Medicine in Suwanee, Georgia. His clinical interests include general outpatient pediatrics, ADHD, sports medicine, and complex care. Before returning to school to earn his medical degree, Dr. Horgan spent three years in the financial sector, but he always knew he wanted to pursue a career in healthcare. After completing several volunteering opportunities, he was confident that pediatrics was his specialty. From 2018 – 2022, Dr. Horgan served as the Flight Commander and a pediatrician on active duty in the air force. He says it was truly an honor to care for the children of active duty parents and/or retirees.
