Quiet room. Steady pace.

I'm Dr. Miriam Mason, a licensed psychologist in Oregon. I work with trauma through EMDR, Somatic Experiencing and attachment-focused therapy. Many of the people I see are firefighters, paramedics, officers, dispatchers, nurses and veterans, and the partners who wait up for them. My approach is calm, direct and body-informed. Hollow Tree Therapy is the room I built for it: private, unhurried and out of the way. You decide how fast we go, and you never have to tell the whole story to begin.

How the work goes

Each method is explained before it is used, and every one of them can be paused.

  1. Individual therapy

    One-on-one sessions for people who carry the job home: nights that will not settle, a body that stays on alert, calls that replay. We start with the present and move at your pace.

  2. Somatic Experiencing

    Body-based work that follows sensation rather than the story. It goes in small steps, so the work stays within what you can tolerate.

  3. Couples sessions

    For partners where one or both of you work shifts or serve. Sessions look at the pattern between you, not at who is right.

  4. Grief and loss

    Company through a death, a loss on the job, or the loss of a career or an identity. Grief has no timeline.

  5. EMDR therapy

    A structured method for distressing memories. Preparation comes first, and you can stop at any point.

What the room is for

Three things you can count on, whatever we are working on.

  • Pace

    You choose how fast we go, and we can stop at any point.

  • Privacy

    Your records stay private except where the law requires otherwise. I explain those limits first.

  • Choice

    You can say no to a method, a question or a topic, and nothing changes in how I work with you.

The path in.

A clear, human way into the work.

  1. 01

    Step 1: Reach out

    Send a message and I will write back. If you would like to hear whether we are a fit first, ask for a short call.

  2. 02

    Step 2: First session

    An hour to talk about what you want from therapy. You do not have to tell me what happened to begin.

  3. 03

    Step 3: The work

    Regular sessions, usually weekly at first, built around your shifts as far as possible.

  4. 04

    Step 4: Spacing out

    Sessions can move to every other week or once a month as you decide, and the door stays open.

What clients say about the room

  • “I braced for a hundred questions. Instead I was asked what I wanted from the hour, and then I was listened to.”

    Terry B.
  • “The room is dim and quiet, and nobody in it needs me to be fine.”

    Gina S.
  • “She explained every step before we took it, and she stopped when I asked her to. That mattered more than I expected.”

    Dagoberto M.
  • “I did not have to tell the whole story to begin. We started with the week I was having, and that was enough.”
