She acted in at least twenty-one Broadway productions between 1902 and 1945, appearing in such long-running plays as A Pair of Sixes, Baby Mine and The Late George Apley. In the 1920s Troutman, with her husband, portrait painter Waldo Peirce, joined the colony of American expatriates in Paris that included Gertrude Stein, F. Scott Fitzgerald, Zelda Fitzgerald and Ernest Hemingway.

A Pair of Sixes, originally titled The Party of the Second Part, is a farce in three acts by Edward Peple that made its Broadway debut at the Longacre Theatre on March 17, 1914. The piece was produced by Harry Frazee and achieved a run of two hundred and twenty-seven performances at the Longacre before closing in the third week of September 1914.
