Find a psychiatrist in California — covered by insurance

Hi there, I'm a board-certified Psychiatric Mental Health Nurse Practitioner whose practice is rooted in one foundational belief: every person deserves compassionate, individualized mental health care — regardless of background, circumstance, or the barriers and challenges they've faced along the way.

I focus on the treatment of depression, anxiety, and life's traumas, with a particular dedication to individuals from underserved and marginalized communities who have historically faced systemic barriers to quality mental health care.

All care is grounded in evidence-based practice, blending the most current clinical research with individualized judgment and patient-centered values. As a lifelong learner, I actively pursue continuing education and emerging best practices in psychiatric care — because excellence in medicine requires ongoing growth, humility, and a willingness to be taught by both science and the patients who make this work meaningful.

I welcome patients of all backgrounds and identities, and I am honored to walk alongside each person on their journey toward healing, wholeness, and hope.

I know finding the right mental health provider can feel overwhelming my goal is to create a welcoming judgment free space where you feel heard understood and empowered to take an active role in your treatment.

The boring details: I offer both telehealth and in person psychiatric services telehealth appointments are available to patients anywhere in California with in-person visits offered in San Bernardino and at my Brentwood satellite office by appointment.

My philosophy: I firmly believe mental health treatment works best when it is collaborative. My goal is to create a space where you feel heard, respected, and actively involved in developing a treatment plan that fits your unique needs and goals. Whether you are struggling with anxiety, depression, ADHD, mood disorders, or other mental health concerns we will work together to help you move forward toward lasting wellness.

I have over a decade of experience as a psychiatric nurse practitioner and previously spent nearly 10 years as a neonatal intensive care (NICU) nurse. These experiences have shaped my whole-personal approach to care and deep appreciation for clinical connection between physical health, emotional well-being, and family dynamics.

I offer both medication management and supportive therapy taking time to educate patients about their diagnosis and treatment options so they can make informed decisions about their own care.

My goal is to help you overcome the challenges you are facing in a safe and comfortable environment to help you improve your quality of life. My passion is helping those with substance use disorders, including alcohol and opioid use disorder, safely detox from the substances and work towards a meaningful and long-lasting recovery. With a decade of experience serving a wide range of patients I am a dual-certified family nurse practitioner and psychiatric mental health nurse practitioner.

My goal is to create a space where you feel comfortable, understood, and supported. I know that seeking help for your mental health can take courage, and I deeply respect each person’s journey. I take time to listen, collaborate, and find a treatment plan that fits your individual needs and lifestyle. I value open communication and believe that healing happens best when we work together as a team.

I'm warm, pleasant, knowledgeable, professional, efficient and approachable.

I specialize in medication management for a variety of mental health conditions. I have over 19 years of experience in nursing and over a decade of experience in nutrition. I like to look at the whole person and approach ways to improve your symptoms. I am here to support you in your mental health.

As a Psychiatric Mental Health Nurse Practitioner, I aim to create a space where you feel heard, respected, and understood.
