William “Bill” Marx Jr. is Grant Thornton’s new market managing principal for the Washington, D.C., area, the Chicago-based U.S. arm of the global accounting firm network announced Wednesday.

Marx succeeds Greg Wallig, who was the company’s metro D.C.-Arlington County market managing principal and added the role of public policy head in June 2023. Wallig left Grant Thornton in June, according to his LinkedIn profile.

Marx has been a tax principal at Grant Thornton for more than 13 years and has more than 25 years of finance and tax experience. From 2015 to 2020, he led the firm’s Tax Accounting and Risk Advisory practices in its Atlantic Coast region.

“Bill has a long track record of providing valuable guidance to public and private companies, and his extensive knowledge will be an asset to our people and clients in the D.C. area,” Jim Wittmer, Grant Thornton Advisors’ managing principal for the Atlantic Coast region, said in a statement.

Before joining Grant Thornton in 2011, Marx was managing director of tax services at Smart Business Advisory and Consulting, which rebranded to LECG Business Consulting after merging with financial services management consulting firm LECG in 2010. Grant Thornton purchased LECG’s tax and business consulting groups in 2011.

Prior to that, Marx was the director of tax at utility construction company InfraSource Services, according to his LinkedIn profile. He has also worked for Comcast and PricewaterhouseCoopers.

“Grant Thornton has an incredible team in place in the D.C. region, and we’re providing a level of high-touch service that’s tailored for the broad range of organizations based in our nation’s capital — both inside and outside of the government,” Marx said in a statement. “I can’t wait to expand our footprint in this unique community and bolster our peoples’ collective skillset.”

Marx holds bachelor’s degrees in education and accounting from Pennsylvania State University. He also earned a master’s degree in taxation from the University of Tulsa. He often leads classes and panels at events hosted by the Financial Executives Networking Group, the Tax Executives Institute and the American Bar Association, according to a news release.
