Presence Shift

A personal psychology practice

Welcome. I’m Sean Sullivan, a licensed clinical psychologist based in Muir Beach, California.
In my psychotherapy and coaching practice, I work with individuals navigating stress, anxiety, relationship challenges, life transitions, performance demands, and questions of meaning and direction.
My approach is collaborative, evidence-based, and grounded in contemporary psychology and neuroscience. After gaining a clear understanding of your situation, we work together to develop practical, sustainable changes aligned with your goals and values.
Therapy is not about fixing or optimizing who you are. It is about reconnecting with clarity, agency, and a deeper sense of self-trust.

Presence as a foundation

Over time, my clinical work has increasingly centered on a simple observation: regardless of what is happening in life, when attention returns fully to the present moment, people regain access to calm, perspective, choice and inner peace.
This insight led to the development of The Presence Shift® — a brief, structured practice for returning to presence in real-life moments. While Presence Shifts emerged from clinical work, they are not therapy and are offered separately from psychotherapy.
Presence is not a belief system.
It is an experience that can be returned to.
