Dr. Marietta’s journey began in a small Kansas town and encompassed 14 years of post-high school education. In early September 2021, he realized his lifelong ambition of serving a Pacific Northwest community, providing vital support to cancer patients during their most challenging moments.

“I’ve always been passionate about radiation therapy,” Dr. Marietta explains. “The opportunity to work alongside Oregon Health & Science University physicians at Roseburg’s Community Cancer Center is truly a dream come true. When I visited in January, I immediately connected with the community and felt at home.”

Dr. Marietta pursued his undergraduate studies at Kansas State University near his hometown, majoring in mechanical and nuclear engineering due to his love for mathematics. Motivated by a personal experience, he chose a path in cancer care, driven by a desire to make a meaningful difference.

“What I find most rewarding in radiation oncology is the chance to build meaningful relationships with patients,” he shares. “Many are overwhelmed by their diagnosis, so I prioritize listening, explaining their condition thoroughly, and discussing treatment options in depth.”

Reflecting on his relocation to the Pacific Northwest, Dr. Marietta recalls, “Since childhood, I’ve been captivated by the region’s natural beauty. It’s been a lifelong dream to live here.”

His opportunity came when a fellow medical resident alerted him to an opening at a Roseburg cancer center, solidifying his decision to specialize in radiation oncology.
