Tri-Cities Cancer Center's executive director Thomas Cothran announced his retirement Wednesday after serving 7 1/2 years.
"Tom grew services offered to cancer patients and the community in a way that will positively affect the health care of our region for years to come," Jeff Petersen, the cancer center board's chairman, said in a news release.
During that time, the cancer center campus grew with the addition of the HAPO Medical Oncology wing, which houses Columbia Basin Hematology and Oncology. The center's library, the Ralph R. Peterson Cancer Resource Library, and its resource center also expanded.
The cancer center is a partnership of Lourdes Health Network, Kennewick General Hospital, Kadlec Regional Medical Center and the Tri-City community.
After Cothran steps down on April 19, Tom Corley, former Lourdes chief executive officer, will serve as interim director.
