Jonathan Mantz joined BGR Government Affairs as Managing Director in 2009 after 15 years of experience in political fundraising. Considered a leader and top strategist in his field, Jonathan has raised nearly a half billion dollars to help elect Democrats to federal and state offices. 

Jonathan served as National Finance Director to Senator Hillary Clinton’s presidential campaign throughout 2007 – 2008 and was responsible for creating and implementing fundraising strategies and managing a staff of 60. He led the campaign to raise over $235 million in an 18-month period. During 2007 alone, the year before the primaries were held, the Clinton campaign raised more than $118 million, breaking all fundraising records for a non-incumbent presidential candidate. By many accounts, his fundraising operation was considered one of the strongest-run departments of any Presidential campaign.

In 2006, he served as Finance Chairman for New Jersey Governor Jon S. Corzine and spearheaded the Governor’s national and state-wide fundraising and political operations. Jonathan was a Principal at the premier lobbying/public affairs firm PodestaMattoon. He represented clients and coalitions including Fortune 500 companies, leading hospitals and universities, and orchestrated outreach strategies and messaging to help achieve clients’ political, policy and communications goals.

In 2004, Jonathan became the Deputy Executive Director of the Democratic Senatorial Campaign Committee (DSCC). In this role, he revitalized the DSCC’s fundraising operation, more than doubling what the committee raised in 2003. He led the DSCC – at the time a minority party – to out-raise the National Republican Senate Committee (NRSC) for the first time ever. In his year at the DSCC, the committee raised more funds in a single year than any in its history as he collaborated with the Democratic Caucus in the Senate.

From 1997 – 2002, Jonathan was Finance Director of the Democratic Congressional Campaign Committee (DCCC). Working closely with Democratic Leader Richard Gephardt and respective DCCC Chairs Representative Martin Frost, Representative Patrick Kennedy and Representative Nita Lowy, as well as the entire Democratic Caucus, Jonathan was the architect of the Committee’s fundraising program. The DCCC raised more funds during that five-year period than at any time in its previous history. 

Born in Philadelphia and a graduate of Ithaca College in New York, he has two sons and the family resides in Maryland. Jonathan serves on the advisory board of Petra Solar.
