After a significant personal trauma, Kelsey was able to find stillness and acceptance through her personal practice. She began living with less resistance and learned how to appreciate the present moment.

From beginners to experienced yoga practitioners, Kelsey meets students where they are and helps them safely discover their body’s unique potential. She encourages her students to listen to their body’s emotional, physical, and spiritual needs as they explore and learn their edges. Kelsey loves to make people laugh and draws on this ability to create a lighthearted and supportive space for every student. Kelsey empowers every student to take their yoga practice deeper into their lives both on and off the mat. Her classes will leave you with an enormous smile and a greater sense of love and compassion for yourself and others.
