UC San Diego Health infectious disease and internal medicine physician Thomas Martin, MD practices from 4168 Front Street in Hillcrest, with a clinical focus on HIV care, opportunistic infection management, and adult primary care for immunocompromised patients. Clinical coordination for HIV patients runs between this clinic and the Owen Clinic, UCSD's dedicated HIV/AIDS treatment center on the Hillcrest campus that handles antiretroviral therapy, resistance genotyping, and preventive PrEP workflows. Day-to-day caseload covers internal medicine continuity visits, chronic infection follow-up, pre-travel vaccination consults, and post-exposure prophylaxis evaluations. Community-based wraparound services — case management, dental coordination, mental health linkage — connect out to the AHF Wellness Center - San Diego for resources that sit outside the academic medical center's direct clinical scope. The highest-acuity workups here involve new HIV diagnosis intake, antiretroviral regimen selection based on genotype resistance panels, and real-time coordination with the UCSD inpatient infectious disease consult service when admission becomes necessary.
