Karuna Brand Ambassador Erin Stack

In the years before starting her own business, Erin Stack earned her Bachelor of Science in Exercise Physiology from Truman State University. She worked as a pharmaceutical sales representative.

In 2001, Erin found her true passion Bikram Yoga, which is also known as hot yoga. Her love for yoga inspired her to become a Certified Bikram Yoga Instructor in 2002. A year later, Erin and her business partner, Carol Stocks, decided to live out their dreams and open their own yoga studio, Pure Hot Yoga. Together, Erin and Carol keep St. Louis sweating!

When she is not practicing yoga, Erin and her husband spend their time raising their two very spirited, healthy young yoginis. Erin tried to keep her daughters happy and healthy, which is just one of the reasons that she chooses Karuna beverages!

I believe that what you put into this life, you get our of it. This applies to your family life, social life, work, your yoga practice, and especially your body. Fuel your body with healthy foods (and drinks)!
