Our Story

A Long History

Just as cancer care has evolved over the past four decades, so has our practice.

Our story begins in the late 1970s when Dr. Edward Orlowski, Dr. Peter Rasmussen, Dr. Robert Granatir and Dr. Paul Jacquin began a partnership to help patients diagnosed with cancer and blood disorders. Dr. Bud Pierce joined them in 1994.

Five years later, Drs. Orlowski, Rasmussen and Pierce launched Hematology Oncology of Salem. Soon, we began bringing on new partners to better serve Salem and Willamette Valley.

Today, as Oregon Oncology Specialists, we’re one of the last physician-owned oncology practices in the Pacific Northwest. We pride ourselves on providing compassionate, individualized care to all.
