“I love the esprit de corps of the team here, and the collaborative nature of our approach,” says Dr. John Geisler, Gynecologic Oncologist at Cancer Treatment Centers of America® (CTCA), Atlanta.

Dr. Geisler is a renowned physician and researcher focused on gynecologic oncology. His work on fertility-sparing therapies, uterine and ovarian sarcomas, and radical surgery for ovarian cancer and other gynecologic malignancies have led patients from around the world to seek his care.

After completing his Bachelor of Science at the University of Michigan, Dr. Geisler completed his Doctor of Medicine at Indiana University School of Medicine. His postgraduate training began with a residency in Obstetrics & Gynecology at Loyola University Medical Center, followed by a preliminary medicine residency and four-year residency in Obstetrics & Gynecology at St. Vincent Hospitals and Health Service. He received the prestigious Galloway Fellowship at Memorial Sloan Kettering Cancer Center in New York. He then completed fellowships in Pelvic Surgery and Gynecologic Oncology, at the University of Iowa Hospital & Clinics.

Dr. Geisler has held numerous professional and academic positions. He was a gynecologic oncologist in private practice for several years in Indiana, where also served as Director of Oncology Research at St. Vincent Hospital & Health Services. He later became Professor of Obstetrics & Gynecology and Director of Gynecologic Oncology at the University of Toledo College of Medicine & Life Sciences, where he was also Associate Program Director of the Obstetrics & Gynecology Residency. He later became Chief of the Ob/Gyn Clinical Service and Director of the Ob/Gyn Third-Year Clerkship. Most recently, he was a Gynecologic Oncologist at a large regional medical center in Georgia and Professor of Gynecologic Oncology at the Georgia Regents University/University of Georgia Medical Partnership.

U.S. News & World Report named Dr. Geisler a Top Doctor in the nation for several years and he has also been ranked among the top 100 medical professional worldwide. He has won awards for teaching and research, and serves on the editorial board and as peer reviewer for the most influential journals in gynecologic oncology.

Dr. Geisler has conducted numerous federally funded clinical trials that have advanced the treatment of gynecologic malignancies. He has published more than 120 papers on the care of women with ovarian, endometrial, cervical, vaginal and vulvar cancer in influential medical journals including Cancer,  Gynecologic Oncology, Journal of Cancer Therapy, International Journal of Gynecologic Cancer, and American Journal of Clinical Oncology, among others.

Licensed by the States of Illinois, Oklahoma, Georgia, Indiana and Ohio, Dr. Geisler is Board Certified in Obstetrics & Gynecology and Gynecologic Oncology by the American Board of Obstetrics & Gynecology. He is a member of the American College of Obstetricians & Gynecologists, the Society of Gynecologic Oncologists, the International Gynecologic Cancer Society, the American Association for Cancer Research, and the American Medical Association.  

Dr. Geisler joined CTCA® Atlanta in August 2015. Some of his innovations include the incorporation of robotic surgery into the treatment of gynecologic malignancies and personalized therapy using genomics to help determine the optimal chemotherapy regimen. In October 2015, while continuing to serve patients at the Atlanta-area hospital, Dr. Geisler began seeing gynecologic cancer patients at CTCA in Tulsa.

When he is not at CTCA, Dr. Geisler spends time with his wife, who is also a gynecologic oncologist at CTCA, and their three children.

"Dr. John Geisler seemed very knowledgeable; we like him very much. He apologized for and explained why he was an hour late for appt as soon as he arrived on the floor. Would have been nice if the nurse had explained as soon as it was apparent he would be late. We waited the full hour without an explanation/nurse contact. Were starting to pace the hallway/try to find someone who knew just before he arrived."
