Rebekah Villarreal, MD, provides psychiatric evaluation and medication management in eastern Chula Vista through LifeStance Health's Boswell Road office near the Eastlake corridor, having completed medical training at the University of Pennsylvania Perelman School of Medicine. Pharmacological treatment plans for anxiety, depression, ADHD, and mood-spectrum disorders require precise dispensing coordination, a workflow supported by neighborhood pharmacies including South Bay Pharmacy. The practice offers both in-office and telehealth psychiatric appointments through the LifeStance Health network, which operates approximately 580 supported clinicians across California. Acute psychiatric presentations that require same-day medical clearance coordinate with walk-in diagnostic facilities such as Perlman Clinic Chula Vista for laboratory work and physical examination prior to psychotropic initiation. Highest-complexity cases involve polypharmacy management across three or more concurrent psychotropic classes, including atypical antipsychotics, selective serotonin reuptake inhibitors, and mood stabilizers titrated through serial metabolic-panel and hepatic-function monitoring.
