“To be able to stay involved in building healthy and sustainable communities keeps me grounded as an individual, while staying connected to humanity at large.”

“I am excited about the future; I’ve found something in which I am passionate about, that I can build a career in, while helping to save the environment. Just as important is the fact that I am also empowered to help others in a way that that benefits us all. As a Workforce Development Manager, GRID Alternatives provides me with a great opportunity, not only in which to learn and grow, but also to give back.”
