Who I work with
I'm Christina Mathieson, LMFT #115093, founder of My Mental Climb. Here's who I work with: couples rebuilding trust or reconnecting intimately; individuals working through trauma, sexuality, or the patterns that keep showing up in their relationships; people figuring out ADHD, neurodivergence, or identity questions they've been sitting with for years.
I also work with anyone who's tired of sexuality being treated as a taboo topic in therapy. In my room, sex is a normal, healthy part of being a person, and desire is something we can actually understand.
You don't have to pretend any part of that is smaller or simpler than it is.
My approach
Here's how I work. I hold a comprehensive sex therapy lens alongside Gottman Method training, which means I can move fluidly between relationship dynamics, sexual health, trauma processing, and identity work.
You don't have to repeat your story to three different specialists, or wonder whether the therapist in front of you is the right one for this particular part of your life. I can sit with all of it.
What I want you to know: showing up is the hard part, and you're already doing it. My work is warm, direct, and grounded in the research. I use humor in the room, and I'm just as comfortable sitting with what's uncomfortable to name. Whatever you're working on is learnable, workable, and worth the time.
