Steven Stokes, Psychiatric Nurse Practitioner - Board Certified

I became interested in psychiatry as a student nurse at Washington State University. As a Registered Nurse, my professional interests found me a place on an adult psychiatric inpatient unit; apart of a team of dedicated mental health providers. Enjoyment came from sharing the stories and struggles of patients recovering from acute and chronic mental illness. I jumped at the opportunity to return to WSU, continue my education and become a Psychiatric Nurse Practitioner in 2010. After five years of psychiatric staff service at the Washington State Department of Corrections, I eagerly joined the Eyerly Ball team on May 1, 2016. My passion is to meet and form healthy therapeutic relationships with our patients. I continuously look forward to serving the communities of Ames and Des Moines. I currently live in Washington State.

Location: Tele-Medicine, Cropp Clinic and Eyerly Ball Clinic in Ames.
