Support the Mastery Harrity Wolfpack
As a lifelong athlete, Principal Warshawer was thrilled to bring an athletics program to his middle school students at Mastery Harrity. Not only do sports programs help students stay in great physical shape, but they also teach kids how to become more self-confident, overcome challenges and work as a team. And because they have to maintain good grades to participate, sports also helps them academically.
Even with all of those benefits, maintaining school sports programs can expensive. That’s why we need your help.
