Foster Andersen

is a quadriplegic survivor of a spinal cord injury who put himself through college in New York as a manufacturing engineer.

From 1987 to 1990, Foster worked with the Center for Independent Living in Berkeley, then in 1990 moved to Santa Cruz, and there formed Shared Adventures to serve the disabled population of the Central Coast and Bay Area.
