Garrison Baptist Church is completely self-sufficient and self-governed.  No organization or affiliation has any control or power to govern GBC. However, Garrison  voluntarily cooperates with the following organizations for the purpose of expanding our missional impact in NH, New England, and all over the world.

Baptist Convention of New England
 Garrison is also partnered with 242 Baptist churches through ME, NH, VT, MA, CT, & RI. a portion of our weekly offering goes to help plant new churches and to support ministries like disaster relief and provide church health resources. Through our cooperation with the BCNE, we are also able to support the International and North American mission efforts of the Southern Baptist Convention.
