Karma Yoga Center, Denver

When she took her first yoga class more than a decade ago, Katrina Gustafson knew two things instantly: she wanted to teach yoga, and she wanted to share its incredible benefits with as many people as she could. In 2010, Katrina opened Karma Yoga Center, where students of all levels gather throughout the day.

The studio's classes begin to unfold in the early morning and don't stop until later in the evening, and most are accessible to beginners. In addition to a packed class schedule, Karma offers retreats, teacher training, and even spa services, including massages.
