Eastern Orange County California Alumnae Chapter is a group of dedicated Tri Delta members who have found a connection through sisterhood. We span many generations but the values of Tri Delta hold us together. EOC was founded in 1957 and our chapter members come from our western border of Garden Grove and Anaheim, North to Fullerton and Brea and east to Yorba Linda and South to Tustin, Santa Ana and Irvine and many cities in between. We welcome all alumnae members who would like to connect with sisters and enjoy activities together.
