Located in Woodbury County in northwest Iowa, Pierson was one of over twenty communities across the state to debut new brick post offices in the late 1990s and early 2000s. In a Sioux City Journal article, postmaster Bonnie Saxen indicated she had been working with postal officials “for years” to get a new, larger facility. “Finally our dream came through.” The “dream” post office was roughly 1,600 square feet, almost three times larger than the previous facility. Postal service was established in Pierson in 1884.
