Eastern Orange County California Alumnae Chapter is a group of dedicated Tri Delta members ho 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 we gather from the area from Garden Grove east to Yorba Linda and Brea and South to Tustin and Santa Ana and many cities in between. We welcome all alumnae members who would like to connect with sisters and enjoy activities together.
