No. You will only need to complete one application for you and/or your family, group, business or organization, which will be used for current, upcoming and future placements at city events and programs. However, you may be asked to complete a new application if you have not volunteered within three consecutive years, or the length of our application retention period. Some volunteer opportunities may require additional paperwork as necessary. This might include volunteer blood donors, department positions, or positions requiring additional background checks. To sign up to volunteer at City events and programs after your application has been submitted, contact our office by phone or email: 636-379-5417 volunteer@ofallon.mo.us You can also reach out on Facebook or Twitter.
