IN-PERSON PASADENA | ONLINE IN CALIFORNIAServing clients in Pasadena, Sierra Madre, and greater Los Angeles.
Therapy that helps insight become integrated, embodied, and lasting.
Depth-Oriented Therapy
Many people reach a point where insight alone is no longer enough. They may understand their patterns intellectually yet still feel disconnected from lasting change.
My work focuses on integration — helping clients translate emotional insight, transformative experiences, and moments of deep awareness into meaningful and sustainable shifts in everyday life.
Through a trauma-informed and somatically grounded approach, therapy becomes a space where insight, embodiment, and lived experience come together.
Integration is where meaningful change begins.
My approach
My work integrates trauma-informed psychotherapy with somatic awareness and nervous system regulation to support meaningful and lasting change.
I focus on:
Understanding how the nervous system shapes emotional patterns and resilience
Moving beyond insight into embodied integration
Somatic awareness and gentle attention to physical and emotional experience
Trauma-informed pacing that supports safety and deeper processing
Translating transformative experiences into sustainable change
This approach allows insight, experience, and embodiment to work together — creating deeper and more integrated transformation.
I’m Jill Sumiyasu, a therapist in Pasadena, California. I support individuals navigating life transitions, deep personal growth, and transformative experiences through trauma-informed psychotherapy and integration-focused work.
