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.
It's believed that more than 30-50 percent of individuals with mental health issues do not seek treatment or help. Congratulations, you have already taken a step in the right direction. Just like how a fractured bone causes discomfort and pain, poor mental health also causes day to day discomfort and malfunction. Continuing my analogy, one would expect to take medicine and use a cast to recover from such an injury. I will work with you to understand the situation that you are in and together we will come up with a safe and effective plan. My goal is to get you back up on your feet again without having to feel burdened by your mental health.
