After founding in 1978 what became the Cultural Council of Palm Beach County, Dreyfoos led efforts that culminated in the 1992 opening of the fully funded Raymond F. Kravis Center for the Performing Arts, cultural centerpiece of Palm Beach County. He remained its board chair until 2007, and remains a board member for life and its single largest donor at $7,000,000. As of June 30, 2016, the Kravis Center ranked in theatre venue ticket sales #11 in the world, #6 in the nation, and #1 in Florida.
