Callas will serve in the firm’s government affairs and public policy and tax groups.
Prior to joining Steptoe & Johnson, he was a senior tax counsel to Speaker of the House Paul Ryan and among the chief architects of the Tax Cuts and Jobs Act legislated in December 2017.
Speaker Ryan has said about Callas: “He laid the groundwork for our eventual success with his early work on draft reform legislation while at the Ways and Means Committee, and he drove us over the finish line as my senior tax counsel in the Speaker’s Office.
Callas is a Capitol Hill veteran who spent 15 years working on tax issues at the committee level and for Republican leadership.
The firm expects Callas to provide great value to clients, from large multinational corporations to trade associations, in navigating the new US tax laws.
