“My clinician sent the agenda the day before, so I walked in knowing what we would cover. I did not spend the first ten minutes bracing.”
Our services
Therapy for autistic and ADHD adults and teens. Every service can be adapted to how you work.

Individual therapy
One-on-one sessions at the pace you set, using methods such as ACT and CBT, adapted for how you process. We agree the agenda together at the start.
Routines that fit your week
Masking and burnout
Work, school and relationships
Self-understanding after a late diagnosis

Teen therapy
Sessions for teens, with a parent or guardian involved at the start. Your clinician explains how consent and privacy work under Washington rules before the first session.
School and friendships
Sensory needs and routines
Telling family what you need
