About Our Church About Our Church. . . Williams Memorial United Methodist Church began its service on the O'Fallon area in the early 1800's. Tradition has it that the Reverend Jesse Walker held his services within the walls of Fort Zumwalt in 1807. Since 1808, our church has been located in various locations in the O'Fallon area and is presently located at 307 West Pitman. We are a growing congregation with over 680 members.
All persons are welcome without regard to national origin, race, or status.
Any person may participate in church programs, and after taking vows of church membership, be admitted as a member. We are currently in transition. Our Church office is still at 307 W. Pitman, O'Fallon Missouri. While our new facilities are being built we have worship services at Fort Zumault North High School Auditorium at 1230 Tom Ginnever Ave. 1230 Tom Ginnever Ave.
