Studio Owner

Mary Liff began her journey to barre3 ownership as an instructor in New Orleans, LA and later in Tulsa, OK. As a former dancer and cheerleader, Mary was always looking for a workout that would keep her motivated, challenged, and energized but what she found in barre3 was so much more. Its bright, vibrant community, holistic approach to wellness, and the commitment to innovative fitness is what truly made her love barre3. After years of working as a cardiac critical care nurse and of dedicated barre3 practice, Mary is honored to share her love for barre3 with the Boulder, CO community where her aim is to create balanced bodies and empower her clients from within.
