Over its first 50 years, the SEF changed its direction several times.
In many cases, the SEF's mission was much more oriented to promoting music in America, American artists, and American music professionals.
In the 21st century, the SEF's mission has become much more oriented towards developing the leadership skills of collegiate members of Phi Mu Alpha Sinfonia Fraternity.
In 2006, the Board of Trustees hired Matthew Garber, the SEF's first Director of Development, to increase the SEF endowment and expand its programs.
At that time the Foundation announced it wouldn't seek a replacement.
