A post office named "East Windsor" had been established in the eastern part of Windsor Township in about 1860. This office was transferred to Dimondale and renamed in 1872. In 1878 the Lake Shore and Michigan Southern Railway came through and the area was given a station referring to it as Dimondale. By 1880 the settlement had seven shops: a sawmill, a grist mill, two millinery shops, a planing mill, and several machine shops. In 1906, Dimondale incorporated as a village. From 1929 to 1963, Dimondale had its own high school, until it merged with the Holt School District. This occurred after the school district ran into tax issues due to the sparse business landscape in the village. The final Superintendent for Dimondale was Harvey E. Wood, a school administrator who later moved to Holt's system as the Transportation Manager, then eventually to Ingham Intermediate School District (IISD) as Vice Superintendent. Dimondale almost merged with the Eaton Rapids School district, however due to Mr. Wood's prior mentor/student relationship with Holt's Superintendent (Maurice Pernert), the merge with Holt's school system took place.
