Peter Cellarius

Wholeness, connection, and peace are what Peter Cellarius helps his clients work toward — not as abstractions, but as lived realities in their closest relationships and within themselves. Drawing on two decades of clinical practice, Peter works with individuals, couples, and families navigating anxiety, trauma, depression, and the fractures that quietly erode intimacy over time. He brings particular depth to couples work: how two people lose each other, and how they can find their way back.

His therapeutic toolkit is precise and evidence-grounded. Peter is certified in Emotionally Focused Therapy for couples and Somatic Experiencing for trauma, and is trained to Level 3 in Internal Family Systems. He also draws on EMDR, Acceptance and Commitment Therapy, and Ericksonian Hypnosis. This range lets him meet each client where they actually are — whether that’s a couple whose arguments now unfold in text threads rather than face to face, a person carrying grief or abandonment, or someone who simply wants a more honest relationship with themselves.

Before becoming a therapist, Peter spent over twenty years in corporate leadership — in roles spanning marketing, business development, and organizational strategy. What stayed with him from that chapter was the work he loved most: helping people grow. That instinct now shapes every session. Sessions are available in Los Gatos and online.
