Board certification from the American Board of Psychiatry and Neurology dating to 1987 anchors Seymour Peter M MD, a psychiatry practice operating from 4060 Fourth Ave in Hillcrest since the practitioner relocated to San Diego in 1990. The clinical focus runs through long-term treatment of addictive personality patterns and adult mood disorders, with prescribing capacity coordinated alongside psychiatric nurse practitioners including Bryan Amaro, DNP-PMHNP when caseload pressure demands additional medication-management bandwidth. Affiliation through Scripps Mercy Physician Partners provides hospital admitting privileges and a direct line into the Scripps Behavioral Health inpatient unit when adult or adolescent patients age 16 and up require acute stabilization. Overflow referrals during full-caseload periods route to peer psychiatrists clustered in the same Fourth Avenue medical corridor including Addario Dominick MD, since the block concentrates a dense node of board-certified psychiatric offices facing the Scripps Mercy campus. The most complex casework involves long-arc treatment of patients with co-occurring addictive personality structures layered onto primary mood disorders, where psychodynamic therapy and medication adjustments unfold across years of weekly contact rather than brief medication review visits.
