Biographical Statement

Since leaving residency, I have been in private practice in my childhood home of Phoenix. I serve as Medical Director at Cancer Centers of Northern Arizona in Sedona, Arizona. Over almost 29 years of clinical practice I have helped develop and build several new freestanding clinics and participated in the affiliation with several hospital based clinics. Working with my partners we have developed a private practice with a strong research agenda. We have been a full member site for the RTOG for many years. I have had a strong clinical interest in brachytherapy, particularly prostate brachytherapy, which has been a major part of my practice for more than 25 years. I am particularly proud of this and continue to enjoy following these patients years and decades after their initial treatment.

Working in a private practice setting or with collaborators across institutions, I have authored more than 40 peer reviewed articles and hundreds of scientific presentations. In addition, I regularly serve as a reviewer for many journals in our field.

As an outgrowth of this clinical research exposure, I was able to expand my interests into organized medicine; first through the American Brachytherapy Society where I served as President and into ASTRO where I have developed a passion for Health Policy. This has allowed me to develop a clear understanding of the economics of our field, but also a deep understanding of the entire health policy world with its many stakeholders and competing agendas. Four years on the ASTRO Board, many more serving on the CPT Editorial Panel and more than a decade in our Health Policy Council have taught me about the importance of these many viewpoints. It has given me experience of representing ASTRO to various other medical organizations and societies and in front of those critical government bodies (Congress, CMS, GAO) where our fate is often decided.
