Therapist and so much more
I have operated a therapy private practice since 2014 where I specialize in serving folks who consider themselves outside of the mainstream, especially those who speak the language of pop culture. Through this work I have had the opportunity to gain expertise in the intersection of pop culture and psychology and contribute to numerous books and blogs on the subject. I also literally co-wrote the book on Therapeutic Fanfiction – Starship Therapise: Using Therapeutic Fanfiction to Rewrite Your Life and provided my voice to the audiobook.
Interviewer, presenter and consultant
Over a decade as a clinician paired with a background in theater, voice, and dance makes me a unique and compelling presenter. I have had the privilege to be a TEDx speaker, a keynote presenter, as well as a panel moderator and panel participant at innumerable comic conventions. I also co-host both the Starship Therapise podcast, and the Dark Side of the Mat podcast.
All of my experience has culminated in being a dynamic educator and mental health consultant. I am an adjunct instructor at St. Mary’s University of Minnesota in the Marriage and Family Therapy Master’s program, where I focus on helping students discover their authentic voices.
I am proud of the work that I do: mind, body, and fandom.
