George Matysik


A native of Lower Northeast Philadelphia, George’s love for Philadelphia’s Parks and Recreation began while he was playing baseball at Jardel Recreation Center and Burholme Park, where he was the perennial leader in two statistical categories: hit-by-pitch (HBP) and errors (E). Having cast aside his career in professional sports, George enrolled at the University of Pennsylvania, where he earned his degree in urban studies, while working his way through the school as a janitor. Armed with his experience in urban studies, George took a position as advisor to several prominent area elected officials, where George began his career in public service.

George most recently served as Director of Government Affairs and Public Policy for Philabundance, where he led the development of Fare & Square, the nation’s first non-profit grocery store. George also recently served as President of country’s preeminent senior hunger relief organization—the National CSFP Association—and was founding Executive Director of Feeding Pennsylvania, a collaborative non-profit of the Commonwealth’s food banks. George is Founder and former Co-Chair of the Friends of Mifflin School, an organization dedicated to providing resources to his neighborhood’s community public school.  He also serves on the boards of Mercy Career & Technical High School and the Pennsylvania Resources Council.

In his free time George is an avid traveler, reader, and parks and recreation user, though mercifully has retired his bat and glove. George lives in the East Falls neighborhood with his wife, Alix, and his diabolical miniature pinscher, Duke.

KATIE BREINER, public policy Manager

Katie grew up hiking, biking, and playing softball in Philly's parks and recreation centers.

Armed with a degree in Environmental Studies from the University of Pennsylvania's College of Arts & Sciences and Management & Sustainability from the Wharton School of Business, Katie wants to transform public spaces so that they promote environmental and social resiliency. 

At the Parks Alliance, Katie uses geographic information systems (GIS), database design, and research to manage information and tell stories about Philly's public spaces.
