Services
Psychiatry
Our psychiatrists provide comprehensive evaluations and medication management for mental health conditions. Services include diagnostic assessments, prescription of psychiatric medications, and ongoing monitoring to optimize treatment effectiveness. Combining medication with psychotherapy when appropriate, our board-certified providers treat ADHD, depression, anxiety, bipolar disorder, and complex co-occurring conditions across all age groups.
Behavioral Therapy
Specialized behavioral interventions using Applied Behavior Analysis principles address challenges across the lifespan. Our BCBA-certified clinicians conduct functional behavior assessments and develop individualized intervention plans for autism spectrum disorders, ADHD, and behavioral issues. Services include caregiver training, social skills groups, and neurodiversity-affirming approaches that build practical adaptive skills for daily living success.
Transcranial Magnetic Stimulation
FDA-cleared TMS therapy offers non-invasive treatment for depression and related conditions. Using targeted magnetic pulses to stimulate brain regions regulating mood, this evidence-based treatment provides lasting relief with minimal side effects. Our certified providers deliver 30-minute sessions five days weekly for 6-9 weeks, with most patients experiencing symptom improvement within weeks without anesthesia or medication dependence.
Psychological Assessment
Licensed psychologists conduct comprehensive evaluations to diagnose mental health conditions and identify cognitive strengths/weaknesses. Services include psychoeducational testing for learning disabilities, diagnostic assessments for ADHD/autism, and specialized evaluations for school accommodations. We provide detailed reports with evidence-based recommendations for treatment planning and educational support tailored to each patient's unique needs.
Telehealth Services
Secure video conferencing enables remote access to psychiatry and psychotherapy services across California. Patients receive the same quality care from home through individual/family therapy sessions, medication management, and behavioral health consultations. Virtual services maintain continuity of care with features like electronic prescriptions, insurance billing, and flexible scheduling options for those with mobility or transportation challenges.
