Diversity and Inclusion

The mission of the Oregon Geriatrics Society is to improve the health, independence, and quality of life for older adults in Oregon. We believe that equal protections and treatment are fundamental to aging wellness. OGS stands against systemic racism, discrimination, prejudice, harassment or violence towards anyone – regardless of age, race, cultural background, nationality, ethnic origin, disability, religion, immigration status, gender, gender identity or sexual orientation. As an organization representing professionals in the care of older adults, we stand against any discriminatory policies or actions. We envision and will strive for a nation where everyone is treated equally.
