I am a Psychiatric Nurse Practitioner (PMHNP) who believes that true and lasting healing happens when we treat the whole person—mind, body, and spirit—not just symptoms. I approach each patient with compassion, curiosity, and deep respect, ensuring you feel empowered to explore your healing journey in a safe and supportive space.

I believe quality mental health care starts with feeling heard and respected. I take a collaborative, patient-centered approach and work to understand the whole person, not just symptoms. My goal is to provide a supportive, nonjudgmental space while offering thoughtful, evidence-based psychiatric care tailored to each individual’s needs.
I am a dual-certified Psychiatric Mental Health Nurse Practitioner and Family Nurse Practitioner, providing whole-person care that recognizes the connection between mental, emotional, and physical health. I specialize in treating anxiety, depression, and Women's Health, and I offer a compassionate, nonjudgmental space where you can feel heard, supported, and empowered. Outside of my practice, I enjoy traveling, event decorating, and spending quality time with my family. I believe maintaining balance and personal fulfillment is an important part of overall well-being, and I bring that same perspective into the care I provide.
I’m dedicated to providing compassionate, evidence-based mental health care for individuals of all backgrounds. My goal is to create a safe space where you feel supported, understood, and empowered to take control of your mental well-being. I value collaboration, transparency, and genuine connection in the healing process.
