All of the above references list parishes by the official community they are in, and unless you are very familiar with the local geography and willing to read through an entire state's listing, not very helpful in finding nearby parishes.
One of the easier ways to do this is to enter the YAHOO Yellow Pages, select the community you are interested in, and then search for orthodox. You will get a listing of most of the Orthodox parishes in the vicinity, arranged in order of distance from the community center, with addresses and telephone numbers. You can then check the directories above to find out which jurisdiction a parish is with, times of services, etc.
