In 1999, college student Sarah Nuse needed a way to make car payments after she was fired from her restaurant job. Heeding the advice of her dance-instructor mother, Nuse decided to teach dance classes to young children at a local daycare. More than two decades later Tippi Toes has more than 30 units currently in operation and successfully negotiated a deal with Mark Cuban on ABC’s “Shark Tank,” survived the subsequent collapse of that deal and became one of the most popular names in children’s enrichment programming. Tippi Toes is on track to cross the milestone 50-unit mark by 2023.
