The Eta Psi Chapter was originally founded on February 28, 1958. The original chapter was maintained until it fell apart in 1976. After 39 years of dormancy, a group of thirteen men resurrected the fallen chapter. The new founding date is April 26, 2015. With an ever growing group of brothers, the Eta Psi Chapter of Phi Mu Alpha Sinfonia aims to advance music in America through performances of original works by American compositions as well as spreading music through the philanthropy of the Mills Music Mission.
