Ruth Adepetun, psychiatric and mental health nurse practitioner has been in practice since 2015. Ruth is helping Pullman patients through telepsychiatry services with Palouse Psychiatry & Behavioral Health.

Ruth offers medication management services to patients across the lifespan (ages 6 years and older) in Washington.

She has a variety of clinical interests; however, she specializes in mood disorders, PTSD, anxiety disorders, and psychotic disorders.

Her motto is “Whole Health Begins With Mental Health” and she believes in empowering her patients to take ownership of their health-related decisions. Ruth approaches her work in behavioral health (as more than just a job necessary to make ends meet, but) as a calling; she sees it as “This is what I was born to do.”

Her practice style involves working with (instead of talking at) her patients by establishing and maintaining a good therapeutic rapport, and she views it as an amazing opportunity and privilege to instill hope and to help bring about change and healing in people’s lives.

Outside of work, she enjoys spending time with family, cooking new dishes, reading, (binge)watching movies and traveling.
