MARY IN STUDIO

I believe the best Pilates session meets you where you are, then gives you room to surprise yourself.

I’m a Marin County–based movement instructor with a background in ballet and experience teaching Pilates and barre. I currently teach at BodyRok in Mill Valley and Muse Body Collective, where I lead heated mat Pilates. My private sessions bring that range together: Pilates fundamentals, athletic challenge, careful cueing, and programming shaped around you.

Whether we’re working on a reformer, moving in a heated studio, or meeting at home, my goal is for you to leave feeling stronger, more connected, and confident in what your body can do.
