Radiation Oncology Physicians

Dr. Richard T. Chung, M.D.

DR. Richard Chung, MDDr. Richard T. Chung, MD attended undergraduate school at Stanford University and medical school at the University of California, Los Angeles. In 1994 he completed his residency at Stanford in the field of radiation oncology.

Fascinated by Alaska, Dr. Chung relocated to Anchorage that same year to practice his passion – oncology – at the Anchorage Radiation Therapy Center. Since then, he has been a champion of bringing new radiation therapy technologies to the community so that patients and their families can receive cancer treatment close to home.

In 2006 Dr. Chung and the Anchorage Radiation Therapy Center opened a satellite facility to better serve the growing Mat-Su community.

In 2013, with the help of Dr. Stephen Settle, Dr. Chung brought in the Leksell Gamma Knife® Perfexion™, the most accurate and advanced radiosurgery technology available. And so began Alaska Gamma Knife Center at Anchorage Radiation Therapy Center.

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

Dr. Stephen H. Settle, M.D., Ph.D.After graduating from Stanford University with a PhD and earning his MD from Vanderbilt University School of Medicine, Dr. Settle completed his residency training at the MD Anderson Cancer Center. He was then 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, including the use of Gamma Knife to treat patients with intracranial disease.

Dr. 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, 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® Perfexion™, for non-invasive treatment of both cancerous and non-cancerous tumors and conditions in the brain.

"I am so thrilled to be working with Dr. Chung and Dr. Yordy to bring cutting-edge oncology care to Alaska. I really enjoy establishing a diverse practice, and bringing the skills that I've developed over the last two decades to help Alaskans with a variety of different cancers. The truth is, cancer treatment is currently undergoing a revolution, and using modern tools we are able to help the majority of patients."

Dr. John S. Yordy, MD, PhD

Dr. Yordy is a graduate of the Medical Scientist Training Program at the Medical University of South Carolina, where he earned his M.D. and Ph.D. degrees. Following the completion of residency in Radiation Oncology at MD Anderson Cancer Center in Houston, Dr. Yordy joined the faculty at the University of Texas Southwestern Medical Center in Dallas, Texas, working as a physician scientist. He worked in the clinic as well as directed a translational research lab testing new drugs that could be combined with radiation therapy to make radiation treatments more effective.

Prior to medical and graduate school, Dr. Yordy was able to visit and experience many different parts of the world, as well as work in several interesting jobs.

"I traveled to Alaska three times before moving permanently to the Valley. I always wanted to live in Alaska and I am honored and feel fortunate to have joined Dr. Chung and Dr. Settle in delivering high-quality radiation therapy to anyone in need of this treatment. I look forward to a long-standing relationship with the community and treating patients with the highest level of care. From the time I was a child, I have always felt a calling to serve others. I am thrilled to be working in the Valley, continuing to follow my calling, and helping patients here that need radiation therapy."
