New providers

Royce Ryker, FNP-BC


A family member’s stage-4 colon cancer diagnosis is what drove Royce Ryker, FNP-BC, to become a Gastroenterology provider. “It could have been prevented if recommended surveillance had been performed.” Helping to discover ways to improve someone’s health and well-being is both a passion and a focus for her. “A one-size-fits-all approach does not apply to digestive health. Each person brings their own story. My job is to provide the longest-lasting benefits for patients.” Ms. Ryker and her husband have three children. She raises Labradoodles and volunteers in youth programs and ministries.

The Corvallis Clinic is pleased to welcome these other new providers:

Yvonne Keep, FNP-C, Family Medicine
Tavis Cowan, M.D., Immediate Care Center
Herbert Harman, M.D., Psychiatry/Behavioral Health
