Trende holds a B.A. degree from Yale University, an M.A. in political science, and a J.D. from Duke University.

In 2021, Trende was selected as one of two redistricting special masters by the Supreme Court of Virginia, after it was tasked with redrawing the state's congressional and legislative districts following the 2020 United States census. Republican legislative leaders Tommy Norment and Todd Gilbert had included Trende as part of a replacement list of nominees for the post, after the three nominees on their initial list were all disqualified by the Court for suspected partisanship.^[7][8][9]
