Mary Galeti
Program Manager

Mary Galeti has always wanted to make the world a better place. After graduating from Kent State in 2005, she hit the road, serving a number of political candidates for office. Deciding she would like a job that kept normal hours, she joined the Grassroots.org team. Now she is excited to be the Grassroots.org Program Manager.

Mary believes in the great American road trip, and the great European backpack. When she can, she loves to enjoy a nice glass of wine and some snobby cheese. She’s also a sucker for getting lost in an art museum, taking a nice nap, or watching a good film.
