Communications Director – Brian Purchia

Brian Purchia is the Communications Director for Protect Our Defenders and has been with the organization since its launch. Described by Craigslist founder Craig Newmark as “genuinely innovative,” Brian has served as a news media adviser and spokesman for former San Francisco Mayor Gavin Newsom,, Green For All and other social change organizations. Brian was described by the San Francisco Chronicle as Newsom’s “go-to guy for social media” for his implementation of a groundbreaking new media strategy called “gutsy” and “brilliant” on NPR.

In Newsom’s new book Citizenville, the current Lt. Gov. of California says, “as I started my second term as San Francisco Mayor I was dismayed as how far behind we still were technologically. Police cars weren’t equipped for email. City websites weren’t set up to take meaningful feedback online. We were surrounded by some of the best and brightest minds technology, but were still operating as though we were in a time warp. I hired a former Voice of America reporter named Brian Purchia as my new media director and asked him if he could figure out how to fix this problem. That was the beginning of a two-year period in which we transformed our city government. We started digitizing, mashing up, and opening up everything we possibly could — far beyond what I had initially imagined when I brought Brian in.”

Brian is recognized as a “Gov 2.0” leader for his work to improve civic engagement by making government more accessible through tapping into the power of social media. Before working in government and for social change organizations, Brian worked in media, as a reporter in Washington, DC.
