Andrew Rosenberg

Founding Partner

Andrew Rosenberg is co-founder and co-leader of Thorn Run Partners. Launched in 2010 as a two-person boutique, Thorn Run is today recognized as one of the largest and most impactful government relations and strategic communications firms in the country. Prior to starting Thorn Run, Rosenberg spent a combined two decades on the staff of Senator Edward M. Kennedy (D-MA) and as a policy lawyer, public affairs specialist, and lobbyist at several of Washington’s top firms.

Known for his strategic acumen and deliberate, campaign-style approach to tackling client challenges, Rosenberg is a highly sought advisor and public speaker on matters related to both politics and policy. Respected journals including Politico, the Washington Post, Roll Call, Bloomberg and the Hill routinely call upon on him for insights and quotes.

In addition to providing the firm’s clients with high level strategic counsel, Mr. Rosenberg also serves as a respected and effective Democratic lobbyist. Having spent years previously with two of the nation’s top public relations agencies, Rosenberg believes strongly in the importance of coordinating strategic communications with government relations as a means of accomplishing one’s policy objectives. It is with this concept in mind that he created TRP Engage, the firm’s unique platform of communications capabilities focused exclusively on supporting lobbyists’ work to move the needle on policy development. Along these same lines, Rosenberg, and the firm more broadly, is well recognized as an innovator and pioneer in the conception, creation, and execution of successful issue-based stakeholder coalitions designed to accomplish clients’ policy goals.

Mr. Rosenberg also boasts significant experience in the political arena. He was a co-founder and Senior Advisor to Draft Obama, the leading national pro-Obama grassroots organization prior to the Senator becoming a presidential candidate. Over various election cycles, Rosenberg has served as an election law consultant to the Democratic National Committee, a surrogate for presidential campaigns on health care and Middle East policy issues, and as a regional coordinator for the DNC’s Voter Protection Initiative.

Mr. Rosenberg received his B.A. in History and Russian Studies at Amherst College, and obtained his law degree, as well as his masters in Urban and Environmental Planning, at the University of Virginia.

Mr. Rosenberg resides in Washington, DC with his wife, Jenny, and children, Kate and Max.
