Cathy Saunders wanted to start a nonprofit organization to help the homeless, but she didn’t know where to start.The Charlotte resident found the answers she needed at Central Piedmont Community College. And she’s not alone. CPCC is seeing increased interest in its classes related to creating and running nonprofit groups."There’s a lot of individuals that just want to get out there and give back where they can,” says Renee Hode, director of the college’s Institute for Entrepreneurship.The institute provides support for small startups or existing businesses through training, counseling and access to resources. It began offering nonprofit-related courses in 2007. Since then, more than 250 individuals have enrolled in the classes, Hode says. Individual classes cost up to $125.
