I grew up in a small town in Hawaii, then came to Southern California and began studying psychology in 2001. I completed my master’s degree at Fuller School of Psychology in 2010 and served children and families at a community mental health agency for 10 years, also starting a private practice in 2015. While I loved island life, I’ve put down roots here through friendships, involvement in my community, and my love of LA’s cultural diversity.
I have 15+ years of experience working with individuals and couples who have experienced trauma, both directly and indirectly. My specialty is those going through a loss, suffered emotional trauma, or are victims of violence. Unaddressed individual trauma can often lead to anxiety, depression and difficulties in developing / maintaining loving relationships. Couples can struggle with unhealthy patterns of communication and need alternative tools to better understand each other. With a warm, collaborative, and evidence-based approach I support clients facing issues such as anxiety, grief, life changes and relationship challenges.
I work with adults facing ADHD, anxiety, trauma, PTSD, sleep issues, and substance use, offering clear, practical help—no guesswork. You might feel overwhelmed, stuck, have trouble sleeping, or struggle to focus. We follow a structured approach to understand your situation and develop a treatment plan that progresses. I provide psychiatric evaluations, medication management, and focused follow-up using evidence-based and trauma-informed strategies. The process is simple, with clear steps and adjustments based on your progress. If you're ready to proceed, reach out.
