Because of the long distances between churches, which could be over a hundred miles between the farthest churches, regionalization of churches was implemented. The Diocese has been divided into four regions – North, South, East and West in Southern California and one region in Hawaii. This makes coordination of services, regional meetings among local priests, deacons, and Sunday School teachers, more feasible and practical. Also, services such as retreats and other activities can be combined.
The first church acquired by newly immigrant Copts to Southern California was St. Mark in Los Angeles. The number of churches has steadily grown, as reflected in the following list.

Big Bear Lake
Serving Los Angeles, Santa Monica, Hollywood, and the metropolitan area
