Practicing Since: 1992

Dr. George Daneker, a Surgical Oncologist at our hospital in Newnan, Georgia, brings nearly 30 years of surgical experience to his position as Chief Medical Officer at Cancer Treatment Centers of America® (CTCA).

One of the first doctors to join the brand-new team at our Newnan hospital, Dr. Daneker notes that he is excited to practice medicine in an integrated, multidisciplinary cancer center.

With a career covering the breadth of surgical oncology, Dr. Daneker has had extensive experience in management of patients with intraabdominal cancers (liver, pancreas, bile duct, stomach, intestine, colorectal, adrenal), skin and soft tissue cancers (melanoma and sarcoma) and breast cancer. Board certified, he is also skilled at advanced, high-tech procedures, such as laparoscopic surgery and robotic procedures.

Originally from Williamsport, Pennsylvania, Dr. Daneker graduated cum laude with a bachelor’s degree in biology from Loyola College of Baltimore in Maryland, and earned a medical degree at the University of Maryland School of Medicine in Baltimore. 

He then headed to Cincinnati, Ohio to complete an internship and residency in general surgery at the University of Cincinnati Medical Center. Dr. Daneker also completed clinical and research fellowships at Harvard Medical School and The University of Texas MD Anderson Cancer Center.

Dr. Daneker first joined the CTCA® team in 2011 as a staff surgical oncologist at our Philadelphia hospital and later served as Chief of Staff at the Newnan hospital. Prior to working with CTCA, Dr. Daneker served as the Director of Surgical Oncology, Oncology Research and Robotic-Assisted General Surgery at St. Joseph’s Hospital in Atlanta. 

Other prestigious appointments he has held include Chief of General and Colorectal Surgery at St. Joseph’s Hospital, Cancer Liaison Physician for the American College of Surgeons Commission on Cancer and Director of Oncology Research in the Department of Surgery at the Emory University School of Medicine.

Additionally, Dr. Daneker has shared his knowledge with others in numerous teaching positions as an adjunct faculty member of the School of Biology at Georgia Institute of Technology, adjunct professor at the Center for Cancer Research and Therapeutic Development at Clark Atlanta University and as an assistant professor in the Department of Surgery and Winship Cancer Center at Emory University School of Medicine, to name just a few. Most recently, he was named an adjunct professor of biology at Georgia Tech.

Dr. Daneker has received numerous acknowledgments for his work, ranging from the Armand Hammer International Travel Award from the Society of Surgical Oncology and the “Top Doctors for Cancer” by Newsweek magazine in 2015.  He was also named among the “Top Cancer Doctors” by Castle Connolly for the second year in a row in 2016.  Among his other recognitions is his continuing appearance as one of the "Top Doctors in Atlanta" (Atlanta Magazine), "Best Doctors in America" (Best Doctors, Inc.), "America’s Top Surgeons" (Consumer's Research Council of America) and was recently named by U.S. News and World Report in the top 1 percent of surgeons in the United States.

He has been invited to present by the American College of Surgeons, Instituto Nazionale Tumori (Naples, Italy), Japanese Surgical Society (Nagoya, Japan), Keystone Symposia in Cell Biology (Keystone, Colorado) and the Society for Surgical Oncology.

Dr. Daneker has authored many journal articles, abstracts and book chapters on cell biology, tumor biology and surgical oncology. He co-edited The Mont Reid Handbook: The University of Cincinnati Surgical Manual, 2nd edition in 1990 and has been a guest reviewer for The Annals of Surgical Oncology.

Despite the esteemed recognition he has received for his work throughout the years, Dr. Daneker is most proud of “having the privilege to help patients regain their health and life.”

Bonnie Bajorek Daneker, Dr. Daneker’s wife, is President/CEO of Write Advisors, a literary consultancy firm. The couple has three grown sons.

The Daneker family has a strong interest in service, especially on the issues of homelessness, hunger, access to medical care and underprivileged girls and women. Passionate about flying, Dr. Daneker holds a private pilot license with instrument rating, and is currently working on his commercial pilot’s license.
