About My Practice

You deserve a provider who truly listens, not just a prescription pad. If you’re considering medication for your mental health, exploring psychiatric care can feel daunting. I believe effective care starts with a real, human connection, a calm, welcoming space where you never feel rushed or reduced to a list of symptoms.

Whether you are navigating anxiety, depression, burnout, or major life transitions, my practice is rooted in healthcare equity, warmth, and respect for all identities.

We can work together on:

  • Comprehensive Evaluations: Getting a clear understanding of what’s going on without any rush.

  • Thoughtful Medication Management: Fine-tuning medications tailored specifically to your body and lifestyle.

  • Integrative Planning: Looking at how physical health, sleep, and stress impact your mood.

  • A True Partnership: Explaining all options clearly so you remain empowered in your care.

Dual Board-Certified Approach: As both a Psychiatric and Family Nurse Practitioner with over a decade of medical experience, I look at the ‘big picture’ of your health—how your biology, lifestyle, daily stress, and emotions all interact.
