He combines strategic thinking with effective skills for the courtroom, the statehouse and the conference room.

Steve developed many of these techniques as a litigator for the US Department of Justice, Tax Division, as chief counsel for the District of Columbia’s Office of Tax and Revenue, and further refined them during his tenure as general counsel for the Council on State Taxation (COST).
