Specialties:
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.











Headway makes it easy to find support for your mental health — from finding the right provider, to understanding costs, to scheduling with ease.
Finding the right psychiatrist in Palmdale starts with understanding the type of care you need. Psychiatrists are medical doctors who can diagnose mental health conditions, prescribe medication, and in some cases offer talk therapy. If you are looking for help with anxiety, depression, ADHD, bipolar disorder, or medication management, a psychiatrist may be a good fit. Psychiatric nurse practitioners (PMHNPs) can also evaluate, diagnose, and manage medication — and are another option available through Headway.
Palmdale is part of the Antelope Valley, where access to in-network psychiatric providers can be limited compared to other parts of Los Angeles County. Virtual sessions can expand your options significantly, connecting you with licensed providers across California who specialize in the care you need. When evaluating a provider, consider their experience with your specific concerns, whether they offer virtual or in-person visits, and how their approach aligns with your preferences. Reading a provider's bio can help you decide if they are a good match before booking.
Psychiatry sessions can be expensive without insurance coverage. Using your in-network benefits is one of the most reliable ways to lower your out-of-pocket costs. On Headway, you can enter your insurance details to see estimated session costs upfront, and your out-of-pocket expense may be as low as $0 per session, though costs vary based on your location and exact insurance coverage. Nationally, Headway partners with over 100 insurance plans, making it easier to find a psychiatrist who is both the right clinical fit and covered by your plan.
