Hi there, I'm Sierra!

I am a California-based Licensed Psychologist with over 10 years of clinical experience supporting adults as they navigate life’s challenges. Whether you’re dealing with anxiety, depression, trauma, relationship concerns, or a life transition, we’ll work together toward achieving emotional well-being and lasting positive changes.

My focus

I enjoy working with adults (21 and over) who may be feeling weighed down by anxiety, depression, relational struggles, or the impact of trauma. My clientele is diverse, and I welcome adults of all ages, cultural backgrounds, and sexual orientations.

My approach

I take a holistic approach to therapy that supports the whole person—mind, body, and spirit. This often includes strategies such as nervous system education, mindfulness-based practices, and somatic healing. I also draw from additional evidence-based approaches such as Cognitive Behavioral Therapy (CBT) and Solution-Focused Therapy.
