Meghan O’Neil, M.D., Ph.D.

Currently not taking new clients

I am a licensed and ABPN board certified psychiatrist with more than 10 years of clinical experience. I offer diagnostic and medication evaluations, medication management, and psychiatric consultation.  I value the positive and often profound effects of psychotherapy, and will work in close partnership with you and your therapist to develop a medication treatment plan that supports your therapeutic progress.

I am happy to assist you in initiating medication for the first time, in optimizing your current medications, in streamlining an overly complicated medication regimen, or in thinking out-of-the-box if medication results have been disappointing in the past.  I also don’t hesitate to use non-pharmacologic approaches when appropriate, including supplements that have research to support their effectiveness, light therapy, and behavioral sleep interventions.  I enjoy working with clients with a wide variety of concerns.

About me: I was born and raised in the Midwest, growing up in Wisconsin and receiving my undergraduate degree in biology and psychology from Luther College in Iowa.  After tiring of cold winters, I migrated to California, where I received an M.D. and a Ph.D. (in Neuroscience) from the University of California, Los Angeles.  After nearly a decade of sun (and smog), I saw the appeal of green trees, misty weather, and hot coffee, and moved up the coast to Seattle for my specialty training in psychiatry at the University of Washington.  Following residency, I completed a fellowship in Addiction Psychiatry also through the University of Washington.   I then worked for several years in a clinic that specialized in the treatment of anxiety disorders and emotion dysregulation before moving to Portland to be nearer to family.
