Kiernan McCullough has a propensity for solving complex problems using simple solutions, a skillset he polished during his studies at Purdue and one that he still applies to his current work in radiation oncology. He is the chief of therapeutic medical physics at Colorado Associates in Medical Physics (CAMP), where he began his career in 2014 as an assistant physicist. On his way up the company ladder, where he is now part-owner, he has spearheaded hospital accreditations, created revolutionary radiation treatment techniques, and standardized radiation therapy across multiple facilities.

His position is unique, in that CAMP is not tied to a single hospital, enabling him to have a meaningful impact across the Rocky Mountain Region. He has practiced at some of the busiest hospitals in the area and provided care to remote destinations that otherwise would be at risk of providing sub-standard care. He has designed, tested and created products, including a novel device for small skin lesions that delivers optimal radiation treatments and can easily be employed in most facilities across the country. Since joining the practice, his leadership has grown CAMP from just two facilities in Colorado to 10 across Colorado, Wyoming, and New Mexico — including one veterinary oncology clinic.

Kiernan's influence is also evidenced in his service to the American Association of Physicists in Medicine, co-authoring the Medical Physics Practice Guideline for linear accelerator performance tests, serving as president of the Rocky Mountain Chapter, winning the Radiation Measurement of the Year Award, and most recently, sitting on the board of directors.
