Addiction therapists & psychiatrists in Petaluma, CA

Clients often describe me as warm, approachable, and easy to talk to. I aim to create a supportive and engaging space where you feel safe to be emotionally open, while also bringing a sense of ease.

At the core of my style is curiosity. I’m drawn to the “why” - why we feel, think, and respond to life the way we do. I take a holistic and at times existential approach, exploring not just immediate challenges, but the deeper patterns, life transitions, and questions of meaning that shape your experience.

I draw from a wide range of personal and professional experiences, including working directly with and overseeing a large and diverse group of clients. This allows me to adapt different techniques and perspectives to support growth, insight, and lasting change. Throughout the process, I remain thoughtful, engaged, and focused on what will be most helpful for you.

I am an LCSW with over 10 years of experience in the field. I've worked in hospital settings, inpatient and outpatient mental health, and telehealth therapy. I draw from a wide range of modalities to provide personalized therapeutic solutions and am certified in EMDR, REBT, and am in training as a sex therapist. I have experience and expertise in treating mood disorders, trauma, LGBTQIA+ issues, and neurodivergent people.

I’m here to make this journey feel gentle, welcoming, and human. I keep things clear and simple so you can focus on what matters, not the overwhelm. My style is warm, encouraging, and a little poetic—because softness helps us breathe. Let’s take this step together, one calm moment at a time.
