Organizational Structure

The Sharing The Good Life Foundation operates out of the MC Companies corporate office located in Scottsdale, Arizona. Our reach, however, extends far beyond our home office as we provide financial assistance to non-profit organizations in location where MC communities are located. This includes Arizona, Oklahoma and Texas. The Foundation is governed by a Board of Directors and the daily activities are the responsibility of the Director of Philanthropy.
