Bipolar disorder therapists & psychiatrists in Westlake Village, CA

My focus

I specialize in working with adults facing depression, anxiety, grief, PTSD, occupational stress, relationship conflicts, cultural and identity issues, and survivors of abuse. I help clients build understanding and chart a path forward using evidence-based approaches.

My communication style

My style is nurturing, accepting, empathic, and personable. I use unconditional positive regard to help you feel safe without judgment. I validate how you feel and normalize your situation so you can feel comfortable and at ease in our work together.

My journey to mental healthcare

I became a therapist because I have always accepted others, regardless of their background or circumstances. I believe in advocating for those who may not otherwise have a voice.

Therapy with me is holistic, engaging, and client centered. I have an extensive background in working with adults, teens, and couples. Clients express they feel deeply listened to and met with an approach directly tailed to meet their needs.

Accepting short-term and intermittent-term clients who are open and ready for immediate positive emotional, mental, or relational shifts.

I'm a Licensed Clinical Social Worker who believes that therapy works best when you feel truly heard — not judged. I bring warmth, honesty, and a no-nonsense approach to our work together. My goal is for every client to leave each session feeling a little more understood and a little more equipped than when they walked in. I work with most major insurance plans, so getting quality care shouldn't have to break the bank.
