About Us

geriatric-medPeachtree Medical Center is a primary care facility providing high-quality healthcare for adults since 1985. Patients range in age from 18 to 100 plus and come to PMC for a broad range of medical conditions. PMC consists of physicians board-certified in internal medicine and family practice, nurse practitioners, and medical assistants. PMC sees patients from a variety of social and economic backgrounds. All types of insurance are accepted by PMC physicians including Medicaid, and Medicare. PMC prides itself on providing quality care to all of its patients, regardless of insurance status. Although the attending physicians at PMC specialize in primary care/internal medicine, several physicians have additional expertise in Preventive Health, Women’s Health, Hypertension, Geriatrics, Pharmacology, Osteoporosis, and Diabetes. All staff and physicians place a strong emphasis on educating patients about wellness and disease prevention.

Our mission is to offer each patient the highest level of thorough, personalized care. To help us achieve this goal, we use a state-of-the-art electronic medical record system that allows for ease in communication with families, specialists, and pharmacies. We also stress continuity of care by providing a medical home where your health can be focused on and optimized. Dr. Zia Khan grew up in Peachtree City and attended Booth Middle School and The Heritage School in Newnan before moving on to undergraduate studies at Loyola University, Chicago, Illinois where she graduated Cum Laude and received her Bachelors Degree in Biology. She also studied at St. George’s University School of Medicine before completing her residency at Maimonides Medical Center, New York. Dr. Khan returns to Peachtree City as a board certified Internal Medicine physician. In addition to private practice, Dr. Khan is the medical director of the Lagrange Nursing and Rehabilitation Center, Southland Health and Rehabilitation Center and Golden Living Dunwoody.

Dr. Rappe was born and raised in Long Island, NY. He attended college in upstate New York at Binghamton University, receiving a Bachelor’s of Science in Biology. He received his medical degree from New York College of Osteopathic Medicine in 2007 then completed his Internal Medicine residency at Lenox Hill Hospital in Manhattan. After becoming board certified in his specialty, Dr. Rappe joined a private practice in Long Island in 2012 in which he saw patients in the office, hospital, and a few nursing homes. After spending a couple of years with that practice, Dr. Rappe decided to relocate to Atlanta. His approach to medicine includes patient education of their medical issues as well as teamwork between physician and patient. He believes this leads to much-improved outcomes.
