Erin O’Leary


As a Psychiatric Mental Health Nurse Practitioner, I use a combination of talk therapy and medication to help people overcome the mental health obstacles they face. Some of these obstacles arise in response to specific challenges like stress, loss or relationship problems, while others are chronic issues that are managed over several years or even a lifetime. In either case, I partner with my clients to create individually tailored treatments designed to help them lead fuller, more rewarding lives.

I enjoy being able to provide both talk therapy and medication management for my clients. However, I still find it very rewarding to play a supporting role when an individual is already working with a counselor and is only in need of the medication management piece. I value the professional relationships I've made with counselors and other providers and enjoy the process of collaborating. There are many occasions where two heads (and perspectives) are better than one.

I am board certified as a PMHNP, and licensed in both Oregon and Washington. I have recently completed advanced training in treatment of substance use disorders to provide Medication Assisted Treatment for clients who are struggling with co-occurring substance abuse and other mental health concerns.

I graduated from OHSU with a Master's of Nursing in 2011. Prior to that I had a very winding road that led me through many different subjects and several different colleges and universities. I have found that mental health nursing has been an ideal balance between the liberal arts and natural sciences. Effective care usually means being able to draw from both sides, to be able to use scientific advances in the service of personal meaning and growth.
