Sonya Soloway

Director of School Partnerships & Instructor

Sonya is a lifelong athlete—and collegiate rugby player— who believes in the need to individualize your practice every day, meeting your body wherever it's at. Born and raised in the heart of Washington, D.C., and a former early childhood educator, she finds immense joy in building relationships, whether it's in her work supporting community-driven school transformation, on that mat, or off. Knowing that success is not about doing it alone, she sees education & fitness as a way to build a community to move that one inch further. 


She is a trained cycle teacher and brings those big moves, high RPMs, and energy to the mat for our core & more class. Focusing on whole-body health, her classes will always be a mix of throwbacks (lover of all things 90s) and current hits, with the occasional D.C. flair.

Sonya teaches core & more, core & cardio, and spin.

Name, Title


Brittney Henderson-Fiestas

Director of Inclusion, Equity, and Justice


Brittney is a local activist and organizer in DC’s Black Liberation movement, an instructional leader at a DC charter school and an Educational Leadership doctoral student at University of Southern California Rossier School of Education. Her fitness journey began after being diagnosed with bipolar disorder 2. Having a background as a pre-professional ballet dancer, she fell in love with barre and became a trained instructor in 2018. Brittney strongly believes and roots her teaching in, what Angela Davis describes as, “radical self-care.” Dr. Davis explains that in order to take care of our collective community and to make change sustainable, we need to take care of ourselves mentally, spiritually, and physically. Radical self-care means “we’re able to bring our entire selves into the movement. It means that we incorporate into our work as activists, ways of acknowledging and hopefully also moving beyond trauma. It is a holistic approach.” With this lens, Brittney’s classes are filled with upbeat music, encouragement, and mindfulness rooted in anti-racism. 


Brittney teaches core & cardio and core & more.

Devyn Brauer


Devyn began working at a spin studio in DC as a way to escape from the craziness of grad school (and to get free classes). After taking enough classes, a hobby turned into a passions and she fell in love with the loud music, dark room and intense connection you share with the people sweating around you. After living in DC for 11 years and teaching spin for 4, she recently moved back home to Philadelphia (Go Birds). When she is not spinning, she is a Speech Language Pathologist for middle school students. Don’t be surprised if her music sometimes sounds like it was chosen by a 13 year old... it probably was.
