I’m a Doctor of Nursing Practice–trained Psychiatric Mental Health Nurse Practitioner with a career shaped by service, compassion, and a genuine love for helping people feel seen, supported, and capable of healing. Before becoming a PMHNP, I spent many years as a CNA and later earned my BSN from the University of the Incarnate Word in 2015 in San Antonio, TX. I worked bedside at University Hospital, transitioned to hospice in 2016, and later served in case management at UTHSCSA. In 2023, I began my DNP–PMHNP program, completing it while working full time at Clarity Child Guidance Center. On December 13th, 2025, I was officially granted the title of “Dr.”, became board certified as a Psychiatric Mental Health Nurse Practitioner on February 9th, 2026, and finally obtained my APRN with the Texas Board of Nursing on March 12th, 2026!

My doctoral project focused on reducing seclusion rates for children and adolescents with autism spectrum disorder using evidence‐based, trauma‐informed interventions—an area close to my heart as a parent of a special‐needs child. I’m passionate about geriatric psychiatry and child & adolescent psychiatry, and I bring a calm, grounded, and collaborative style to treatment.

I also briefly served in the United States Air Force, an experience that strengthened my commitment to resilience, service, and advocacy. Today, I continue to advocate for women affected by domestic violence, helping them reclaim safety, confidence, and possibility.

On a personal note, I’m a mom of two boys, happily married for 11 years, and the proud owner of four dogs. Outside of work, you’ll usually find me drinking coffee, shopping for plants, collecting perfumes, baking, cooking, or spending time with family and friends. These parts of my life help me stay balanced, grounded, and connected—values I bring into every therapeutic relationship.

I believe effective mental health care begins with trust, collaboration, and respect. My approach is empowering, compassionate, open-minded, and culturally sensitive. I provide a safe, nonjudgmental environment where adolescents and adults feel heard, respected, and actively involved in their care. I combine a holistic, whole-person perspective with evidence-based psychiatric assessment, diagnosis, medication management, and supportive psychotherapy to create personalized treatment plans that promote lasting wellness.

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP) with more than 20 years of nursing experience in hospitals, outpatient clinics, private practices, community health centers, and behavioral health settings. I treat a wide range of conditions, including depression, anxiety, bipolar disorder, ADHD, trauma-related disorders, psychotic disorders, and other complex mental health concerns.

My career also includes international humanitarian work with the International Committee of the Red Cross (ICRC), where I cared for individuals affected by conflict and crisis. This experience strengthened my commitment to providing compassionate, culturally responsive, and patient-centered care for people from diverse backgrounds.

In addition to my clinical practice, I am the author of several mental health publications that reflect my dedication to education, evidence-based practice, and improving patient outcomes. I currently provide comprehensive psychiatric care through Oasis Behavioral Health and Elevated Behavioral and Transitional Health.

My goal is to partner with you to develop practical, individualized strategies that improve emotional well-being, daily functioning, and overall quality of life.

What truly sets me apart is my calm, compassionate, and nonjudgmental approach. I believe in meeting every individual exactly where they are, creating a safe and affirming space for open, honest communication. Together, we’ll build a collaborative relationship where goals, preferences, and values guide every step of your care. I am committed to providing stigma-free care; including those navigating challenges related to neurodivergence, substance use, trauma, identity or difficult past experiences. Everyone deserves to be seen, heard, and respected without fear of shame or judgment.
