Washington, D.C. — Thorn Run Partners (“TRP”), one of America’s fastest-growing government affairs firms, announced today the addition of Hayden Jewett as a Partner.
Joining TRP from another downtown firm, Hayden previously served as an in-house lobbyist for a Fortune 200 company as well as a leading non-profit organization. He brings deep expertise in tax, tech, energy, and supply chain policy, and nearly a decade of experience in both Congress and the private sector, where he has built a strong record of legislative achievement and strategic influence across a broad set of industries.
Most recently, Hayden served as a multi-client lobbyist representing companies and associations before Congress and the Executive Branch. His advocacy has helped clients testify before key committees and secure significant short- and long-term federal policy wins. His work spans a range of issues including artificial intelligence, energy, tax policy, critical minerals, and supply chain resiliency. Prior to going in-house, Hayden spent nearly five years on Capitol Hill serving the Texas delegation in the offices of Chairman Roger Williams (R-TX) and John Culberson (R-TX). While there, Hayden helped lead public policy strategy, legislative initiatives, and served as a primary policy advisor for Labor-HHS, Agriculture, and Legislative Branch appropriations subcommittees. He led efforts to protect and advance federal funding of our nation’s hospitals and research centers, and in the wake of Hurricane Harvey was integral in securing bi-partisan support for recovery and relief efforts.
Hayden is Co-Chair of the D.C. Chapter of Maverick PAC and is a member of the Steering Committee. He is also a longtime coach of the Republican Congressional Baseball Team, supporting nearly 40 members of congress each year leading up to the bi-partisan Congressional Baseball Game for Charity held at Nationals Park. In 2016, Hayden served as a congressional staff liaison to President Trump’s inauguration.
“We’re super excited to add Hayden to our team,” said TRP Co-Founder Chris Lamond. “His experience and extensive network of relationships will bring instant value to our firm’s current client base, and we know Hayden will be successful in adding to that roster.”
TRP Co-Founder Andrew Rosenberg added, “In addition to his undeniable track record of success as a consultant and lobbyist, Hayden will make a great colleague. We are very excited to welcome him to the firm.”
The addition of Hayden grows TRP’s roster of professionals to 56.
