In their words

What our clients say

  • “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.”

    Devin R.Client
  • “I kept my camera off for the first month and nobody made anything of it.”

    Marlen A.Client
  • “I can fidget, pace or look out the window while we talk. Nobody asks me to sit still.”

    Taryn B.Client
  • “The emails are short and clear, and the office is quiet. Small things, but they made it easy to come back.”

    Zihan L.Client
  • “My clinician asks how I want to do things before assuming. That is rare.”

    Samir H.Client
  • “Sessions go at my pace. When I need a minute to find the words, there is room for it.”

Therapy and evaluation

Therapy is not an evaluation

Therapy here is a place to work on what is in your way, with or without a diagnosis. An evaluation is a separate assessment, done by a psychologist, that can say whether you are autistic or have ADHD.

  • Therapy at Tarn

    Ongoing sessions on what matters to you. No diagnosis is needed, and self-identified clients are welcome.

  • An evaluation, elsewhere

    A one-time assessment that ends in a written report. We do not diagnose, but we can talk through what to look for.

Our services

Therapy for how you think and work

Methods such as ACT and CBT, adapted so they work for autistic and ADHD minds.

Individual therapy

One-on-one sessions for autistic and ADHD adults, at the pace you set. We agree an agenda at the start of each session and adapt the methods to how you process.

Teen therapy

Sessions for teens, with a parent or guardian involved at the start. Your clinician explains how privacy and consent work before the first session.

Burnout and overload

Practical work on what drains you: sensory load, masking and too many demands at once. We build routines and limits that you choose, and review them as life changes.

Couples and family

For couples and families where one or more people are autistic or have ADHD. We work on how you talk, plan and share the load, with each person’s way of communicating respected.

Work, school and identity

Support with a late diagnosis, a new job or a move to college. We work on what comes next, whatever your path.

About us

Clarity through connection

Tarn Therapy is a small practice for autistic and ADHD adults and teens. Our four clinicians are licensed in Washington, and each session is planned with you: how you want to meet, what we cover and how we keep track.

  • Four licensed clinicians, listed with their licenses below

  • Camera-off, phone and in-person sessions

  • Written agendas and recaps if you want them

  • Adults and teens

Our approach

How we work

Three habits that shape every session.

  • A minimal living room with a low black coffee table, a TV unit and slatted blinds

    Plain and direct

    We say what we mean and ask for the same. You always know what a session is for and what happens next.

    Your pace

    Pauses, breaks and a different plan next week are all fine. You set the speed and we adjust.

    Your body in the room

    Fidget, pace, rock or look away. We do not ask you to sit still or make eye contact.

Common questions

Frequently asked questions

Clear answers before you write.

01Do I need a diagnosis to start?

No. Some clients have a diagnosis, some are waiting for an evaluation and some are exploring on their own. All are welcome. We do not diagnose; if you want an evaluation, we can talk about what to look for.

02What happens in the first session?

You and your clinician talk about what you want from therapy and how you would like sessions to run. There is no test. Your fee is confirmed in writing before you start.

03How often and how long are sessions?

A session is usually 50 minutes. Most clients meet weekly or every other week. You and your clinician set the pace and can change it.

04Do you take insurance?

We bill some health plans directly; details are on the fees page. Write to us and we will check your benefits before your first visit.

05Can I keep my camera off?

Yes. On video you can keep your camera off, or we can talk by phone. Video and phone visits are for clients who are in Washington, where our clinicians are licensed.

06What if my clinician is not the right fit?

Fit matters. If after a few sessions it does not feel right, tell us. We will help you move to another clinician on our team or find someone else.

Ready for a first session?
