Board-certified in addiction medicine and psychiatry, Sarah Mueller Carey, MD practices at Point Loma's Kaiser Permanente Medical Offices on Kenyon Street. Her medication-assisted treatment program includes buprenorphine-based protocols for opioid-use disorder, an evidence-based approach that complements the behavioral-health continuum running through Mental Health Systems Inc. A 1999 Ohio State University College of Medicine graduate with a Stanford psychiatry residency, she transitioned from general psychiatry to addiction medicine after 18 years of dual-practice clinical work. The Kaiser integrated-care model means her prescribing, therapy, and lab monitoring connect within a single electronic health record, a closed-loop system distinct from the independent-practice counseling model at Helm and Harbor Counseling. Her highest-acuity cases involve dual-diagnosis patients managing co-occurring psychiatric conditions alongside active substance-use disorders, requiring synchronized medication adjustments across multiple drug classes.
