Jill Sumiyasu, LMFT

Licensed Marriage and Family Therapist
Pasadena CA
I don't just sit back and nod, and I won't tell you what to do. My clients describe me as present, calm, and someone who makes them feel genuinely heard. The goal isn't just insight — it's helping you feel, respond, and live differently. I work with individuals, couples, and adolescents in person in Pasadena and online across California. Integration support is available whether you worked with me or another provider.
Something meaningful in your life isn't working — even though on the outside, things look fine. You've tried therapy, you have insight into your patterns, but something still isn't shifting. That's exactly who I work with. I'm a licensed therapist in Pasadena, California. Before becoming a therapist, I spent most of my adult life as a successful executive in investment management — driven, accomplished, and always moving. What I didn't realize until my 50s was that the constant motion was keeping me from slowing down enough to feel. Therapy changed that profoundly enough that I left my career, went back to school, and became a therapist myself.
