Operating as the San Diego site within the 11-clinic Advanced Psychiatry Associates California network, the Fourth Avenue Hillcrest office delivers FDA-cleared transcranial magnetic stimulation, Spravato (esketamine) intranasal therapy, and full medication management for treatment-resistant depression and other mood disorders. The TMS device protocol used here is the same FDA-cleared course that interventional psychiatrists like Dr. Kai MacDonald - Psychiatrist/Psychotherapist have championed for unipolar major depression in San Diego. Genetic-based pharmacogenomic testing helps board-certified psychiatrists at the practice select antidepressants without trial-and-error sequencing across SSRIs, SNRIs, and atypical agents. The site treats adults and adolescents for depression, bipolar disorder, anxiety, OCD, ADHD, sleep disorders, and substance use, with telehealth coverage across California for patients who can’t reach the Fourth Avenue suite in person. Inpatient escalation for acute presentations is coordinated with Hillcrest Medical Center at UC San Diego Health a few blocks west. The most clinically intensive workflow is the in-clinic Spravato program, which requires REMS-certified observation, two-hour post-dose monitoring, and a structured treatment-resistant depression diagnosis trail before each session.
