VPSI is a national vanpool service founded in response to the oil crisis of the mid-1970s. The company offers commuters affordable and environmentally conscious transportation to and from work. A subsidiary of Chrysler, VPSI was one of the first vanpool services in the country, and it has since established a wide network of shared commuter programs throughout the United States. The Dublin office is located in an office park at the end of Amador Plaza Road, across from the entrance to I-680.
