The Tongva Native Americans lived in the area, and along with other tribes, in the region for over 8,000 years. These earliest residents, also referred to as the Tongva-Gabrieliño Tribe, of what is now known as San Dimas became part of the Mission Indians after Spanish colonization from the Mission San Gabriel occupied their lands in the late 18th century.

San Dimas, in 1915

The first known European exploration of the area was in 1774, when Juan Bautista De Anza passed through on the first overland expedition of Las Californias, from New Spain-Mexico towards Monterey Bay. The area was originally developed in 1837 with the Mexican land grant from Governor Juan Bautista Alvarado to Ygnacio Palomares and Ricardo Vejar for the Rancho San Jose, then in Alta California.[7] It later became known as La Cienega Mud Springs, so named because of local mud springs that created a riparian marsh and healing place. Palomares and Vejar conducted sheep and cattle operations on Rancho San Jose, also growing crops for consumption by the residents of the rancho. In the early 1860s, a severe drought decimated the ranch's population of sheep and cattle. Ygnacio Palomares died in 1864, and his widow began selling the ranch land in 1865. Vejar lost his share by foreclosure to two Los Angeles merchants, Isaac Schlesinger and Hyman Tischler, in 1864. In 1866, Schlesinger and Tischler sold the ranch to Louis Phillips.[8]
