I am a compassionate psychiatric provider that is dedicated to my practice. I started my psychiatric career as a technician in forensic psychiatry. I worked with individuals who had comitted crimes and were either attempting to determine competency, or were found not guilty by reason of insanity. As my education blossomed, I began working as a nurse on a child and adolescent crisis stabilization unit. I found a massive love for child and adolescent psychiatry and spent most of my career working crisis stabilization and residential psychiatric care for children and adolescents. This gave me significant experience working with many different cultures. After I graduated with my doctorate, I began working psychiatric outpatient. I now see patients of all ages (children 4+, adolescents, adults and geriatric). I thrive on a strong therapeutic relationship and making sure my patients feel heard. I am open minded and non-bias. You are safe with me.
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.

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.
