We believe...Again, this can be found on the web page of a public school in Mississippi.
Faith in God is the cornerstone of our community.
Contact information for the school is as follows:
Sumner Hill Junior High School
400 W. Northside Drive
Clinton, MS 39056
Phone: (601) 924-5510
The school's principal, Willie McInnis, can be reached via email at firstname.lastname@example.org. Please remember to keep any correspondence respectful, and please share any responses you receive.
It may also be worth contacting the Freedom From Religion Foundation and/or Americans United for Separation of Church and State, both of whom make it easy to report violations via online forms. It would probably be most effective if the reports were made by someone in Clinton.
