Indiana University of Pennsylvania, Indiana, Pennsylvania, December 3, 1966-1975; re-established 1977-1978
Alpha Theta Nu, a local sorority founded in 1963, petitioned and was accepted by Alpha Delta Pi with the initiation of 36 charter members held in December 1966. The chapter closed in 1975 as a result of a difficult Panhellenic situation and low numbers. Recolonization was attempted in 1977; however, the group closed again in 1978. Former Province Director Cheryl Appleton has served in many capacities.
