Sharon Duke Estroff, award-winning educator, author, and parenting/education journalist, conceived the idea of Challenge Island® while on maternity leave with her fourth child. Maxed out on late-night reruns of a popular reality TV show, she began wondering if the same basic principles (minus the voting and location) could become a means of motivating her students to take on complex higher level thinking tasks. She poured everything she’d learned about children into developing this idea, incorporating cutting edge research and educational thought. By the time her daughter graduated from 3 AM feedings, Challenge Island® was ready for primetime. She started Challenge Island® in her 2nd grade classroom and began running it as an enrichment business in 2003. Since then, Challenge Island® has been growing by leaps and bounds. She had a hunch the business model would work for other parents and teachers. Challenge Island® was launched as a franchise a decade later. Now Challenge Island® is the world’s #1 STEM/STEAM program by Entrepreneur Magazine’s Franchise 500. With over 100 locations in the USA and abroad, Challenge Island® has touched the lives of over 1 million children in over 6,000 schools and community locations. Challenge Island® is grounded in cutting edge educational thought and at the foundation of S.T.E.A.M Education and 21st Century Learning.

Challenge Island® caught Rebecca Tanag’s attention because of its unique approach to learning: the multi-disciplinary content of the instructional materials; lessons rooted in real-world applications; fun and whimsical hands-on projects that blends science and engineering concepts with arts and crafts; and programming that encourages and fosters collaboration, perseverance, creative thinking and problem solving. The kids learn a lot of things in a fun and exciting way! While Mrs. Tanag’s background is in business, she loved to teach. She had been actively involved in the education ministry of her church for over 10 years and loved working with kids. She brought Challenge Island® to San Diego over 5 years ago and Challenge Island San Diego Central/North has since become one of the acclaimed providers of STEAM-based enrichment program to local schools, libraries, community centers and other sites through after-school classes, field trips, Girl Scouts badge and journey workshops, camps, family science events, birthday parties, and birthday in-class field trips. The Better Business Bureau has given Challenge Island San Diego Central/North accreditation early part of 2020.
