Sarah Rasby, M.A.


Sarah Rasby is no stranger to the fitness instructor substitution process! She has co-owned a yoga studio based in Lincoln, Nebraska since 2013. As the co-owner and Regional Director of her studios, she believes quality instruction is the heartbeat of her studio.

With all the abundant responsibilities that come along with owning a studio, Sarah desired to build a strong, reliable and intellectual system to find and schedule substitute instructors for classes. From all the challenges, mishaps, successes, and meditation, Sub Guru was created!

Sarah is a passionate entrepreneur and yoga instructor. Her vision is to build conscious awareness and integrity within the fitness industry and Sub Guru is the management solution to do just that!

Andra Rasby, M.B.A.


Andra Rasby understands the sports and fitness industry from the inside out. She holds an MBA with a concentration in Sports Business, is a former Division1athlete, and a certified yoga instructor.

As both a client and instructor, Andra is well familiar with group fitness and the operations behind the instructor substitution process. She recognized a disconnect in finding the most appropriate substitutes for group classes. There were too many steps, lost emails, and last minute request.

With a desire to fix this problem, she teamed up with Sarah to design Sub Guru and says, “I want owners, managers, and instructors to spend less time worrying about finding the right teacher and more on the quality of the class.”
