These new providers join Byron Littlefield, DO, Sonia Watley, MD, and Emily Johnson, NP-C at AdventHealth Medical Group Family Medicine at Adairsville Health Park to work collaboratively with patients to accomplish their desired treatment goals with care and compassion.

Dr. Chandler is a board-certified family medicine physician. He values the relationships he develops with his patients and staff, and he is committed to working with patients ages 13 and older to devise the best care plan to meet their needs.
When he’s not providing top-level care to patients as part of his family practice, Dr. Chandler spends most of his time with his own family. Dr. Chandler is a graduate of the University of North Texas Health Science Center Texas College of Osteopathic Medicine in Fort Worth. He completed his residency in family medicine at Floyd Medical Center in Rome, Georgia. He is board-certified in family medicine by the American Board of Family Medicine.
Dr. Johnson is a board-certified family medicine physician. She appreciates the opportunity that family medicine provides her to work with patients ages 13 and older — not just to manage chronic issues but also to educate them on illness prevention. Her goal is to develop patient-physician relationships based on trust and good communication. When she’s not working to provide patient-centered care, Dr. Johnson pursues a variety of interests, including cycling, camping, water recreation and spending time with friends.
Dr. Johnson is a graduate of the Alabama College of Osteopathic Medicine in Dothan. She also completed her residency in family medicine at Floyd Medical Center. She is board-certified in family medicine by the American Osteopathic Board.
Lister is a family nurse practitioner providing care to patients ages 12 years and older. She enjoys the variety that comes with treating a wide spectrum of ages and conditions, and she prioritizes developing interpersonal relationships in the process. When she’s not working hard to meet the health care needs of her patients through treatment and education, Lister likes to spend time traveling, hiking and mountain biking.
Lister earned a Bachelor of Science in Nursing from Kennesaw State University in Georgia and later earned a Master of Science in Nursing from the family nurse practitioner program at that same institution. She is certified as a family nurse practitioner by the American Academy of Nurse Practitioners.
