Heath Bonsall is a Medical Dosimetrist who serves Peninsula Radiation Oncology Center in Soldotna and the Juneau clinic, alternating between the two each month. Before entering healthcare, he spent six years in the U.S. Air Force as an aircraft mechanic, including four years at Eielson Air Force Base near Fairbanks, where he was named Airman of the Year. His decision to pursue radiation oncology was shaped by his mother’s experience with breast cancer; the therapists who treated her later helped train him. He earned his B.S. in Radiation Therapy and M.S. in Medical Dosimetry, and joined the Peninsula team under Dr. John Halligan in 2014–2015, becoming a permanent member in 2016. He has also played a key role in expanding services across the state, including the development of the Mat-Su Valley Cancer Center in Palmer.

Today Heath continues to support cancer care throughout Alaska, collaborating closely with physicians and staff while traveling regularly between clinics. He values the daily connections formed with patients and the lasting relationships that develop over the course of treatment. One of his most memorable experiences was befriending a patient who was a pilot and later going flying with him. Outside the clinic, he has also volunteered with Radiating Hope, joining their 2017 trek to Everest Base Camp and returning in 2018 to assist with training at the Kathmandu Cancer Center.

Heath and his wife, Jenni, live at the base of Hatcher Pass in Palmer with their daughters, Hannah and Malia, and their three dogs. An avid yoga practitioner, he and Jenni built a heated yurt studio on their seven-acre property, which also includes a private lake. He enjoys homebrewing and the dog-friendly atmosphere of the clinics, and finds particular satisfaction in the teamwork and compassion that define the work.
