In 1828, Pleasant Hill saw the arrival of the first settlers to the area and all of Cass County, then called Van Buren County. Records were filed in 1844 making Pleasant Hill a village with about 40 inhabitants. Old Town existed along No. 7 Highway from the cemetery to Maple Lane.

Old Town was the site of commercial Pleasant Hill until 1865. With the coming of the railroad business picked up enormously. Established firms of Old Town moved south to the current business district engulfing the community of Wyoming. Even houses were picked up and moved to the new location. The current train station built in 1903 replaces the Pacific Union Depot built in 1866.
