The Southern Door Business Association was established in 2012 with a handful of dedicated volunteers whose main goal was to promote the great businesses and services in Southern Door County to residents and visitors.  Under the leadership of a volunteer board, our membership has continued to grow!  The association markets Southern Door businesses and services through billboards, the GO! Guide, a local map, presence at recreational shows, and promotion of local events.  We invite you to join us in our quest to promote "Southern Door -- the First Door in Door County."
