Who I Am

Knowing the importance of the therapeutic relationship also means knowing the importance of what each person, whether therapist, facilitator, or supervisor, brings to the space, and what they don't. I am white, non-binary, queer, kinky, neurodivergent, and a former sex worker.

Outside of my time doing therapy, supervising, and training, I enjoy dancing, gardening, home projects, reading (or trying to), comedy, crime dramas, traveling, nerding out over planning and spreadsheets, and hanging out with my two senior dogs - a foxhound named Russell & a Cattle Dog named Bronco.​ I'm equally passionate about sexual freedom, challenging oppressive systems, and queering up the world around me in and out of my role as a therapist.

What I Do

I believe we are our best when we have strong, empowered relationships with ourselves and others and therapy is no exception. I use an eclectic approach to best match your needs and honor your goals. I lean towards a casual, relational yet assertive and steady presence and will challenge you while holding a warm and encouraging space for you to explore and process. You can expect me to crack a joke, curse, and be very human and honest with you in session. 


My training is rooted in systems thinking and queer, feminist theory which allows me to critically examine the various systems we all exist within rather than focus on any particular symptom or issue. I utilize a variety of models to influence my approach such as Narrative, Structural, Bowen Family Systems, and Feminist Theory.


I truly enjoy working with folks from all walks of life, and especially with couples and relationships of non traditional structures. I love guiding folks through transitions whether that be sexuality, gender, non monogamy, and exploring or processing kink dynamics.
