French native speaker, Sophie came to the M/s world through literature. She had been reading M/s novels for as long as she can remember, but as a consent activist in a queer and poly group, she always kept a bit of frustration because of the consent biases in French books (where she always identified as the upscale characters regardless of the gender).

Two years ago, she discovered MAsT groups, attended MsC Worldwide twice, and it was a revelation. She discovered a community whose ethic speaks to her and decided to create a MAsT chapter in Paris with a few people having previous MAsT experience.

Because of the lack of French M/s educational material, she had to create her own content by reading books in English and discussing with other members. That’s how and why she currently delivers most of the classes of the MAsT chapter she is now president of. But the french M/s community is broadening quickly in Paris, and more and more M/s enthusiasts join and contribute.

Sophie now wants to figure out if there is a french-speaking M/s community worldwide and that’s why she proposed to teach in French for MsC 2025.

Sophie is currently building a M/s dynamic with her life partner, Dan, who is also co-director of MAsT: Paris and was a founding member of MAsT: Virginia Beach.

I use a lot of modalities so have a pluralistic/poly 😉 approach, an integrated soup really that includes TA, DBT, Relational, Trauma based, Gestalt, Rogers, CBT, Psychosexual Psychotherapy, neuroscience, Polyvagal theory, Systemic, Somatic and Schema are all ingredients. I see individuals, couples, polycules, families and more and have over 20 years of courses completed and passed.
