Meet The Team Behind Challenge Island

Terri Lowe

Franchise Owner / CEO

Terri Lowe is the Challenge Island CNY Franchise owner for Central New York within Onondaga and Cayuga Counties.  Terri is a mother of four grown children, and grandmother of five.  As a parent and grandparent, she knows the importance of not only kids learning the skills necessary to thrive in this complex world but also to play and enjoy being a kid.  She’s noticed that with all the time she sees being spent using electronics these days that it’s vital that we give our kids time to “unplug” and tap in on their own creative juices to engage with their classmates and friends on a social and emotional level.  She says, “Challenge Island is not only fun and exciting but it also increases kids’ skills in creativity, collaboration, communication and critical thinking.  Terri lives in Marcellus NY and is very excited to offer this Award-Winning program to the schools, kids and families of the communities surrounding her.  Please join her in making sure every child has the opportunity to visit all the fantastic islands with Challenge Island CNY!
