Launched in 2019 under the vision and leadership of Betty Huang, the region offers Associates in Orange County and San Diego County at least three local events a year.

Events are held at some of Orange County and San Diego County's finest cultural institutions. The region also seeks to engage the area's growing technology industry and renowned medical centers.

Although the region is new, the connection between Caltech and Orange County and San Diego County is not. In the late 1920s, Caltech acquired a building at the now-defunct Balboa Palisades Club in Corona del Mar and transformed it into the William G. Kerckhoff Marine Laboratory. Today, that facility is one of the oldest marine field stations on the West Coast.
