Bipolar disorder therapists & psychiatrists in Vista, CA

I am a board certified, doctoral prepared PMHNP. I completed my post graduate at National University in Adult, Child and Adolescent Psychiatry. I earned my DNP from Azusa Pacific University and graduated from CSUSB MSN program. I have been a faculty at CSUSB since 2014. Extensively trained and a certified Trauma-Informed specialist. I diagnose and treat mental disorders including medication-assisted treatment along with counseling for chemical dependency and substance use disorders.

Choosing a therapist is a big decision, and it helps to know a little about the person you’ll be working with. With more than 18 years in behavioral health, I’ve supported people from all walks of life through mental health challenges, trauma, and major life transitions. Whatever brought you here, I’d be honored to walk alongside you as you move forward with more confidence and resilience.

I work with teens, young adults, and families navigating ADHD, anxiety, depression, substance use, identity exploration, family conflict, relationship challenges, life transitions, and emotional overwhelm. Whether you're feeling stuck, disconnected, overwhelmed, or uncertain about what comes next, therapy can provide a space to better understand yourself and move toward meaningful change.

My approach is warm, collaborative, and nonjudgmental. I believe therapy works best when clients feel genuinely understood, supported, and accepted for who they are. Together, we build on strengths, develop practical coping skills, and explore the patterns that may be getting in the way of living a more fulfilling life.

I strive to create a safe and supportive environment where clients can be honest, reflective, and fully themselves without fear of judgment. My goal is not only to help clients navigate current challenges but also to foster greater resilience, self-awareness, confidence, and connection.

I have experience working with children, youth, adults, families, couples but in the last few years, I have shifted my main focus to work with adults who are struggling with anxiety, trauma and depression. I’ve worked in the mental health field for 22 years and been practicing as a therapist for about 10 years. As a licensed marriage and family therapist, I believe that prioritizing mental health is key to happiness and stability in life. Seeking help can be difficult, so congratulations on taking your first step to start therapy.

It is my prayer to build a practice that helps you reach a place where your mental health is truly at the forefront. My hope is that with each appointment—and each day—you feel supported in moving closer to the best version of yourself.
