E. E. Cossentine
President 1930 – 1942

La Sierra takes its name from the original Mexican land grant known as Rancho La Sierra de Sepulveda. The La Sierra Hills neighborhood was home to Hole Mansion built by a wealthy lumber baron, Willits J. Hole, beginning in 1913. This was the focal point of the several thousand-acre Hole ranch which encompassed much of La Sierra and portions of Corona and Norco. The Pacific Union Conference of the Seventh Day Adventist Church purchased property from Hole in 1922 for what is now La Sierra University. A well established unincorporated area, La Sierra voters approved their annexation to the City of Riverside in 1964.
