In 2003, Sharon Estroff was at the height of her Dr. Jekyll and Mrs. Hyde phase. She spent her days as a cheerful, engaged second-grade teacher and her evenings as a stressed-out mom who could barely muster the energy to help her own four children with homework. It was time for a career shift, but as an educator born into a family of educators, she couldn’t imagine straying too far from the school yard. Besides, there were plenty of things she loved about teaching: the creativity and vibrancy; those smiling second grade faces; and perhaps most of all, the predictable promise of the back-to-school season – an annual chance for a new beginning.
So Sharon took Challenge Island, a STEAM program (Science, Technology, Engineering, Art and Math) that she created for her students, and turned it into a full-time gig. She began offering Challenge Island as an afterschool enrichment class in nearby schools while tutoring on the side to make ends meet. Before long, she had created a profitable home-based business that she could run around her family’s busy schedule.
With the popularity of STEM, STEAM and 21st Century Skills in the educational marketplace, Sharon had a hunch that this business model would work for other moms and dads, too. That hunch was right and today, Challenge Island is one of the fastest growing and revered educational franchises in the world. Ranked on Entrepreneur Magazine’s 2018 and 2019 Franchise 500 List and tapped by Entrepreneur as one of the 100 Fastest Growing Franchises in the world, Challenge Island now has 90 units across the United States and Internationally.
