Sarah Rasby, M.A.
CEO + Co-Founder
Sarah Rasby is no stranger to the fitness instructor substitution process! She is a former co-owner of a Yoga studio based in Lincoln, Nebraska since 2013. During her experience as a Regional Director, she found that quality instruction is the heartbeat of a studio. With the many 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 mediation, SubGuru was created! Sarah's vision is to build conscious awareness and integrity within the fitness industry, and SubGuru is the management solution to do just that!
