As a Psychiatric Mental Health Nurse Practitioner, I aim to create a space where you feel heard, respected, and understood. I believe mental health care should be collaborative, practical, and tailored to your unique needs. My approach combines evidence-based treatment with real-life understanding whether that includes therapy, lifestyle changes, or medication management when appropriate.

My goal is to help you feel more stable, confident, and in control of your mental health not just during appointments, but in your everyday life.

I’m here to make this journey feel gentle, welcoming, and human. I keep things clear and simple so you can focus on what matters, not the overwhelm. My style is warm, encouraging, and a little poetic—because softness helps us breathe. Let’s take this step together, one calm moment at a time.

Mental health has long been treated as the forgotten side of healthcare — and for me, that's exactly why it matters so much. As a Psychiatric Nurse Practitioner serving clients across California through telehealth and in-person care, I specialize in helping people navigate depression, anxiety, and ADD/ADHD. I believe that when mental health struggles go unaddressed, everything else in life suffers — and that healing is not only possible, it's necessary. When I'm not supporting my clients, you'll find me out in nature, getting lost in a good movie, or discovering new music — small reminders of the joy and balance I encourage my clients to find for themselves.
