A discrete place to talk about sex, love, and your relationships.

Ari Lewis

(he, him, his) M.A.PP., M.A., Ed.M, LMHC

From kink and BDSM issues to high and low sexual desire—from opening a relationship to figuring out how to navigate polyamorous parenting—jealousy issues, insecurity, compulsive sexual behaviors, infidelity, trauma, existential anxieties, addiction, dating—I work with all things sex, love, and relationships. In my work, I use both cognitive and exploratory strategies to help you lay the puzzle pieces on the table. I look forward to meeting you and helping you fit those puzzle pieces together.

Psychotherapy is a labor of love. Sometimes we will laugh and sessions will feel like a game of fitting the puzzle pieces together. Other times, you may need to cry. And often, you may just need this space to talk. I am here for it all. Together, we will explore a variety of trauma informed and empirically backed treatment methods to ensure that each session is designed to help you heal and grow.

  • Compulsive sexual behavior refers to any ongoing struggles with sexual activity that a person does not want to be engaging in.

    In this group, sexual health is determined by each, individual group member. Some examples of the things group members could be working on include: infidelity in relationships (including both monogamous and consensually non-monogamous relationships), excessive or problematic porn consumption (in this group, you determine what "excessive" or "problematic" means for you), spending money on sexual activities beyond one's means or beyond one's budgetary goals.

    These are just a few examples. In the end of the day, the group members decide what they want to work on. The group is here to help each member with their own, unique goals.

  • Yes, you read that right. Ari has developed an approach to group therapy that incorporates the text of the Harry Potter books into sessions. Harry Potter fans can think of this as an opportunity to engage in play therapy for adults who like Harry Potter. Don’t get the wrong idea, though. Just like any other form of play, this is serious work with serious benefits only available to those willing to invest time and energy into sessions.

    Sessions are 85 minutes. Currently accepting a waitlist to start a new group.

    *Harry Potter Therapy is not affiliated with J. K. Rowling or her companies and the group is very much unaligned with Rowling’s horrifying comments about trans individuals.
