Casey's Accolades


“Not just a queer sex therapist, THE queer sex therapist.”

Robyn Exton, CEO of HER Social App

"[@queersextherapy] is a lighthouse for me in my own self-development and healing. It is the space without shame, without stigma, without narrow-mindedness where I can learn so much about topics that are otherwise taboo or have been historically delivered through a limited lens."

Alyson Stoner, Actress & Mental Health Activist

"Casey is a triple threat! not only a world class therapist, but also a dynamic educator, and phenomenal multi-media platform presenter. Her willingness to delve deeply into various topics of wellness with strong research, and then translate in an easily digestible manner is truly one of a kind."

Joe Petracca, Director, The Americas, Lelo, Inc.

"We have worked with Casey on a variety of partnerships on social and have been so impressed with the quality, speed and results generated from those partnerships. Casey is always on time, on top of requirements and a pleasure to work with."

Kara Miller, Coral App
