Certified sex therapist, author, founder, The Expansive Group, New York, US
“I learned everything I know about sex and relationships in therapy because I didn’t have access to pleasure-positive sex education that was inclusive of queer folks growing up. So many people are in that same boat, wanting to feel sexually and romantically alive but without the tools to do so effectively. I want to provide those tools in a free and accessible way.”
