There are three sources of assistance for emerging UU congregations. All are good and, if they do not have the answers you need, will be able to assist you in connecting with those who do.
Staff of Your District/Region. Each one employs staff people to aid congregations. If you don’t know which district you are in or who your district staff are you will find guidance on the Unitarian Universalist Association website.
Your Neighboring UU Congregation. When asked what resource was most helpful, emerging congregations consistently say their neighboring UU congregations. Many emerging congregations have formed deep relationships with established congregations near them. If you want to find congregations in your area, go to the congregation finder on UUA.org.
