Newtown Medical Associates, located in the Newtown area of Johns Creek, was founded by Dr. James L. Stewart in 2002. Dr. Stewart was joined by Kathie Brown, PA-C in 2012. At Newtown Medical, we provide medical care for adults and adolescents ages 13 and older. Our goal is to provide our patients with the most comprehensive medical care possible. We focus on the whole patient, promoting wellness and providing diagnosis and treatment for acute and chronic medical problems. Our physician, physician assistant, medical assistants and support staff work as a team to provide you with the time and attention that you need. We strongly believe that same day appointments, shorter waiting times, more face time with our providers, and prompt call backs provide our patients with the best primary medical care.
