Jeremy Hauser — Consultant
Jeremy has been with the firm more than six years. A Bay Area native, Jeremy grew up in Oakland and Moraga and attended UC Davis, where he earned degrees in both Political Science and Communication, graduating with honors in each. He was first bitten by the campaign bug in 2011 as a campaign staffer in the hectic and wide-open San Francisco Mayor’s race.
Before joining the firm, Jeremy worked in Washington DC for a top polling firm where he learned the incredible power of sound analytics and gained significant insight into the art of targeted messaging. He also spent an election cycle working in Denver on a highly politicized and heavily contested school board race. Leading his candidate to a sweeping victory, Jeremy saw firsthand the benefits of a diligent and unrelenting grassroots effort and how pounding the pavement can truly move the numbers in a local race.
Since joining CleanSweep Campaigns, Jeremy has focused his skillset on securing much-needed funding for schools, housing and public transit and electing progressive candidates fighting for many of the same causes. His creative approach to multimedia communication — blending traditional direct mail concepts with new media strategies like social media, pre-roll and programmatic digital — has helped his clients stand out from the crowd and win hard-fought races. And as a former Field Organizer, he takes a very hands-on approach in designing effective grassroots campaigns. His clients win in the mailbox, online and at the doors.
Jeremy lives in the Telegraph Hill neighborhood of San Francisco. In his free time, he loves being around family and friends, trying his hand at pick-up sports, listening to live music and exploring the natural beauty of the Bay Area.
