Radiation Oncologists

The Stoddard Cancer Physicians include three radiation oncologists that are located in the Stoddard Radiation Oncology Department - Robert Isaak, M.D., John Triantafyllos, M.D. and Arshin Sheybani, M.D. These physicians provide the most technologically advanced radiation oncology department in Iowa and continue to lead the way in cancer care.

Our physicians are dedicated to educating patients and their families about the treatment process every step of the way. They make sure that all treatments are tailored to each patient's specific need. (Approximately 90 percent of our patients are served on an outpatient basis and we strive to achieve a "no wait" policy for our patients.)
