I am a dual board-certified Nurse Practitioner specializing in both Family Practice and Psychiatric Mental Health. With a foundation in whole-person, evidence-based care, I integrate medical management with psychotherapy and lifestyle interventions to support mental and physical wellness.
My background spans outpatient psychiatry, primary care, home health, and assisted living settings, allowing me to understand the unique needs of patients across all stages of life. I have extensive experience treating mood and anxiety disorders, trauma-related conditions, and chronic medical comorbidities that impact emotional well-being.
I believe in creating a collaborative, compassionate, and culturally sensitive environment where patients feel heard and empowered to take an active role in their care. My approach focuses on building balance—supporting both the mind and body—through medication management, therapy, and integrative care strategies.
Healing is more than the absence of symptoms, it is the restoration of hope, peace, and self-worth. As a board-certified Psychiatric Nurse Practitioner with a Doctor of Nursing Practice degree, I provide faith-based, integrative psychiatric care for adults in California and Nevada. I work with anxiety, depression, PTSD, bipolar disorder, insomnia, addiction recovery, and more. My holistic approach blends evidence-based medication management with nutritional psychiatry, lifestyle strategies, and Christian counseling when desired—strengthening mind, body, and spirit for lasting wholeness.
