Our Team

Stephen H. Settle, M.D., Ph.D.

stephen settleDr. Stephen Settle and his wife always dreamed of returning to their roots on the West Coast, so when he was recruited as the medical director of the Alaska Gamma Knife® Center in 2013, they jumped at the chance to move their four children to Alaska. Dr. Settle is spearheading the Gamma Knife® program at Anchorage Radiation Therapy Center, which uses the latest cancer treatment technology, the Elekta Gamma Knife® Icon™, for non-invasive treatment of both cancerous and non-cancerous tumors and conditions in the brain.

After graduating from Stanford University with a Ph.D. and earning his M.D. from Vanderbilt University School of Medicine, Dr. Settle completed his residency training at the MD Anderson Cancer Center in Houston, Texas. He was later recruited to a joint-faculty position at MD Anderson and the Baylor College of Medicine, where he held dual appointments as an assistant professor.

In addition to treating patients with cancer, Dr. Settle conducted translational research on brain and spine tumors and served as the course director for resident doctors training in radiation oncology. While at MD Anderson, Dr. Settle developed expertise in stereotactic radiosurgery of the brain and spine, becoming a nationally recognized high-volume expert in these fields (click here for a list of key publications in brain and spine radiosurgery by Dr. Settle and colleagues). Dr. Settle has performed over five hundred cases of brain radiosurgery using Gamma Knife while on the faculty at MD Anderson, and here in Alaska as the medical director of the Alaska Gamma Knife Center. When you are selecting a center to perform such a delicate task as brain radiosurgery, you want reassurance that the doctors involved in your care are high-volume experts in this field. When you are treated at the Alaska Gamma Knife Center, you can rest assured that the same specialized equipment and expertise available at major cancer centers in the lower 48 states are now available to you here in Alaska with Dr. Settle and his team.

Aaron S. Kusano, M.D., S.M.

KusanoDr. Aaron Kusano is a born-and-raised Alaskan, joining our practice in 2015. Dr. Kusano completed his undergraduate studies in biomedical engineering at Johns Hopkins University, followed by a master's degree in cancer epidemiology at the Harvard School of Public Health. He is a graduate of the Alaska WWAMI program and during medical school at the University of Washington took a year off to complete a fellowship in applied epidemiology at the Centers for Disease Control and Prevention in Atlanta, GA.

During his residency in radiation oncology, also at the University of Washington, Dr. Kusano was an active researcher in safety in radiation oncology. He continues to lead educational sessions at national conference on radiation oncology quality and is an instructor in the Alaska WWAMI Program.

Dr. Kusano specializes in high dose rate (HDR) brachytherapy, a procedure delivering internal radiation directly into tumors. He is a recipient of the 2016 HDR Brachytherapy Scholarship Award from the American Brachyterapy Society and with a skilled physics team, started the AVRTC HDR Brachytherapy Program, primarily focusing on gynecologic cancers. During his training at the University of Washington, he was active in treatment of patients at the Gamma Knife Center at Harborview Medical Center and incorporates this tool in his practice.

Alaska has always been his home, and he is ecstatic to be back practicing in the neighborhood he grew up in. He looks forward to using his training and expertise within our practice to provide compassionate, top-quality care to Alaskans.
