ESCCO was founded in 1995 as an affiliate of the Executive Service Corps - United States (ESC-US), a nationwide organization of retired men and women who serve as business management consultants to other nonprofit organizations.

There are more than 30 affiliates across the country with budgets ranging from a few thousand dollars to $1.5 million. Each is responsible for its own funding. ESC-US has a web site at
