WASHINGTON, DC – S-3 Group announced today that Chris Arneson has joined the firm as a Principal following a 15-year career on the U.S. Senate Finance Committee, where he served as one of the committee’s most influential Democratic staffers. Arneson has a proven track record of leveraging his deep policy knowledge, far-reaching professional network, and strategic communications expertise to build coalitions and shape the political narrative to achieve policy outcomes.
“Chris brings coveted Senate knowledge to S-3 from his impressive 15-year run at the Finance Committee and further expands the reach of our robust Democratic team,” said Matt Bravo, Managing Partner at S-3 Group. “His recognized ability to convert complex policy into legislative results and experience at the center of major tax and healthcare debates will be a huge asset to our clients.”
During his time at the committee under Chairmen Baucus and Wyden, Chris oversaw policy coordination, strategic initiatives, and private sector engagement across the committee’s broad jurisdiction, including tax, international trade, and healthcare as a key member of the senior management team. Most recently, he led the panel’s Democratic strategy on the 2025 One Big Beautiful Bill Act and the 2023 Fiscal Responsibility Act and previously worked on significant portions of the 2022 Inflation Reduction Act and various COVID relief packages in addition to his central role in the 2017 Tax Cuts and Jobs Act process and the 2013 Baucus-Camp tax reform effort.
