At the Western Pennsylvania Humane Society, peer-to-peer fundraising has become an essential piece of their development, engagement, and outreach strategy. Catherine Olteanu, Director of Development, explained that last year, the local animal services organization raised $26,000 in conjunction with the 2011 Pittsburgh Marathon from peer-to-peer fundraising alone. As of the first week of March 2012, the Western PA Humane Society has already surpassed last year's total and is “set to nearly double 2011's numbers, which is very exciting.” How?
