I am a dual board-certified Nurse Practitioner specializing in both Family Practice and Psychiatric Mental Health. With a foundation in whole-person, evidence-based care, I integrate medical management with psychotherapy and lifestyle interventions to support mental and physical wellness.
My background spans outpatient psychiatry, primary care, home health, and assisted living settings, allowing me to understand the unique needs of patients across all stages of life. I have extensive experience treating mood and anxiety disorders, trauma-related conditions, and chronic medical comorbidities that impact emotional well-being.
I believe in creating a collaborative, compassionate, and culturally sensitive environment where patients feel heard and empowered to take an active role in their care. My approach focuses on building balance—supporting both the mind and body—through medication management, therapy, and integrative care strategies.

Factors to Consider When Choosing a Therapist in Fullerton
Finding the right psychiatrist in Fullerton starts with understanding what kind of care you need. Psychiatrists are medical doctors who can diagnose mental health conditions, prescribe medication, and monitor how those medications are working over time. If you're looking for help with anxiety, depression, ADHD, bipolar disorder, or OCD, a psychiatrist or psychiatric nurse practitioner (PMHNP) may be the right fit. Both can prescribe and manage medication, and both are available through Headway.
Fullerton and the surrounding north Orange County area — including Buena Park, Brea, Placentia, La Habra, and Anaheim — have a range of psychiatric providers, but finding one who accepts your insurance and is taking new patients can be time-consuming. Reading a provider's bio before booking can help you understand their background, specialties, and approach so you can feel confident in your choice.
Psychiatry sessions in the Fullerton area can be expensive out of pocket. Using your in-network insurance benefits is one of the most reliable ways to reduce what you pay per session. On Headway, you can enter your insurance details to see estimated session costs before you book. Nationally, Headway partners with over 100 insurance plans, and many patients pay as low as $0 per visit depending on their plan and location.
