I have 22 years of experience working with children, adolescence, and adults. I am passionate about the work that I do as a therapist and consider it an honor to walk through life's journey with my clients.
I am a board-certified Family Psychiatric Mental Health Nurse Practitioner. I've worked in different practice settings, including private practice, community mental health, homeless and correctional services, and addiction. I treat and manage a range of disorders ( depression, anxiety, bipolar, schizophrenia, PTSD, OCD, addictions, etc).
As a board-certified, doctorally prepared psychiatric nurse practitioner, I treat a variety of mental health disorders using medication management as well as can incorporate psychotherapy within the session based on situational necessity. My focus is across the lifespan, including children and adolescents.
I am a LPC in private pratice. I have work with clients dealing with depression, anxiety, eating disorders, and trauma. I utilize a combination of psychoeducation, skills-building, and talk therapy to help my clients achieve their goals. I have had the honor of working with people of all backgrounds and bringing cultural awareness to the therapeutic connection.
As a therapist, I believe that therapy should be anti-racist, LGBTQ+ and gender-affirming, intersectional, and inclusive.
