Patient Care is Our First Priority

At Active Recovery TMS, our goal is to provide a safe and effective alternative treatment for depression. Transcranial magnetic stimulation (TMS) is an especially important treatment option for those who have not had success with standard depression treatments like antidepressants and/or talk therapy.

From the first time you reach out for a consultation to your last TMS treatment and beyond, your recovery from depression is our primary focus. We hold a high standard of patient care that is extended to all interactions, including coordination of care and regular updates with your referring provider.

Meet Our Providers

Jonathan Horey, MD

Jonathan Horey is board-certified in adult psychiatry and addiction medicine and is the Chief Medical Officer of Active Recovery TMS. Dr. Horey completed medical school and psychiatry residency at Columbia University in New York City where he served as Chief Resident. After residency, he remained at Columbia as an Assistant Clinical Professor of Psychiatry and the Medical Director of Substance Abuse Services at the Columbia Doctors 51st Street clinic. During his time at Columbia, Dr. Horey became familiar with transcranial magnetic stimulation (TMS) while treating patients undergoing the procedure and from colleagues in the Brain Stimulation division at Columbia who were involved in some of the early clinical TMS studies.

After moving back to his hometown of Portland, OR in 2013, he was a staff psychiatrist at Betty Ford-Hazelden Springbrook before taking the position of Chief Medical Officer at Sunspire Health, a national group of residential addiction treatment centers.

Dr. Horey has maintained a private practice in Portland since 2014 and co-founded Active Recovery TMS in 2017 after discovering a lack of accessible TMS treatment in Portland for his patients with treatment-resistant depression. Dr. Horey has lectured widely on addiction medicine as well as on TMS and is an advanced candidate in psychoanalysis at the Oregon Psychoanalytic Institute.

Dr. Horey is currently accepting new TMS patients at our NW Portland (Montgomery Park) location.
