About Colin's Joy Project:
Colin McGrath was killed in 2018 after being struck by a car on his way home from a wonderful day in the park. His life was full of love, laughter, curiosity. Colin lived every minute of his life to the fullest. His laughing eyes, beautiful curls, hilarious voice, and sense of adventure will never be forgotten. His smile made everyone's heart happy.
Since Colin's death, the McGrath family started a 501(c)(3) nonprofit organization called Colin's Joy Project. The mission of Colin's Joy Project is to enhance play spaces and sponsor children and family programming in the South Boston and surrounding communities.
Colin's Joy Project has several active play space projects in development in South Boston inspired by Colin's Creativity Squad, an initiative that engages children in the community to design their own exciting, creative play spaces. Colin's Joy Project has also formed multiple community partnerships to which they have donated over $1.5M in the last 7 years! Through these partnerships, Colin's Joy Project fulfills their mission to bring joy to families the way Colin brought joy to all who knew him.
A donation to Team Colin will support these long-lasting partnerships and future projects. Learn more about our work on our website www.colinsjoyproject.org, and follow us on Facebook and Instagram (@colinsjoyproject) for updates!
