During his first year in office, Greenwalt issued the first driver's licenses in Iowa. He ran for reelection in 1934, losing to Ola Babcock Miller. From 1937, Greenwalt began serving as treasurer of Polk County. The following year, Greenwalt noted that many driver's licenses purchased in December were Christmas gifts. He ran for reelection as in 1940, and served until 1941, when he was commissioned in the Iowa Army National Guard as a lieutenant colonel. J. F. Baillie was appointed by the county board of supervisors to replace Greenwalt. Following World War II, Greenwalt became commanding officer of Jefferson Barracks Military Post, and was succeeded by Malin Craig Jr. before Jefferson Barracks was decommissioned.
