In 1960, he became the Wisconsin state commissioner of taxation, and he supported John F. Kennedy for President. In 1963 Gronouski was appointed Postmaster General, the first Polish-American Cabinet officer.

After he left the Cabinet on November 2, 1965, President Lyndon B. Johnson appointed him to be Ambassador to Poland.
After President Richard M. Nixon took office in 1969, Gronouski became founding dean of the Lyndon B. Johnson School of Public Affairs at the University of Texas at Austin.
