Muckenthaler Cultural Center

In 1965 the property was converted into a cultural center. The Muckenthaler gave their home and grounds to the City of Fullerton. The Cultural Groups Foundation of Northern Orange County was established in 1966 as a non-profit organization. They collaborated with the city in the operation of the center. The center has been in operation since 1966. The Center Circle Guild was established in 1967 to provide extra support and volunteers for various programs. They also maintained the gift shop, funded the annual Florence Arnold Young Artists Festival, the Holiday Home Tour, and provided financial assistance for exhibition-related and education initiatives, among other things.

The Muckenthaler residence was listed on the National Register of Historic Places in 1980, making it a historic property. In the years 1981 to 1984, the facility underwent a comprehensive refurbishment. The first Master Plan for the Muckenthaler was created in 1984, and it outlined the future of the property. The construction of a new outdoor amphitheater took place between 1990 and 1993. The Muckenthaler Cultural Center Foundation was established in 1990 after the Foundation changed its name. 

The Muckenthaler changed ownership in 1994, with the foundation taking over management of the institution and its grounds. The Jane Deming Endowment was established to promote, preserve, and aid the Foundation in its objective of educating and empowering women.
