Trauma and PTSD therapists & psychiatrists in Calabasas, CA

What patterns keep repeating in your life, even when part of you wants something different?

I work with adolescents and adults navigating anxiety, depression, relationship challenges, grief, life transitions, and experiences that have been hard to put into words -- including adoption-related history, infertility, and the emotional complexity of becoming a parent. A lot of what brings people to therapy isn't a single event. It's the quiet accumulation of feeling disconnected, unseen, or like something important has never had space to be worked through. I trained at UCLA and bring both clinical depth and genuine warmth to this work.

I work with adults and couples who feel stuck in patterns that insight alone hasn't changed. Specializing in Veteran care, anxiety, depression, and gender affirming care, I will provide a focused, grounded, and effective approach to therapy. My practice as a Licensed Clinical Social Worker (LCSW) is centered on helping clients clarify what is maintaining their difficulties and develop practical and sustainable ways of shifting them.

As a Psychiatric Mental Health Nurse Practitioner (PMHNP), I’m trained at the graduate level in mental health care across the lifespan. I assess mental health concerns, diagnose conditions, prescribe and manage psychiatric medications, and provide psychotherapy. I also coordinate care with therapists, primary care providers, and other specialists as needed.

I’m so glad you’re here! I provide therapy for individuals navigating life’s most challenging moments. I support individuals facing depression, anxiety, grief and loss, caregiver stress, and major life transitions. My goal is to create a supportive space where healing and self-confidence can grow.

Life can feel overwhelming — thoughts that won't quiet down, family tension that keeps building, or past experiences continue to dictate your present days. Whether you're an individual carrying something heavy, a couple trying to find your way back to each other, or a family navigating a moment that feels too big to face alone, you don't have to keep pushing through without support. I provide a safe space where your culture, your story, and your language are deeply valued. I bring a grounded, tenacious approach to my clinical work utilizing specialized, evidence- based tools to help with processing heavy burdens. Healing is possible and it can start here, so let's walk this path together.
