Setting the Stage for Success

Founded in 1995, the Region 21's SouthWest Arranger Development Program has grown over the years into a well-established training ground recognized by other Sweet Adeline Regions around the world. Region 21 attributes much of the high level of success and dedication to establishing long-lasting mentoring relationships with beginning and intermediate arrangers.

Leaders from Region 21 and Around the World

Region 21 is proud that our active family of Certified Arrangers helped shape and support the Arrangers Development Program. (SWADP). Created in partnership with Region 11, the program functions jointly with guidance and input from both Regional Management Teams and Education Development Coordinators from both regions. The program has consistently cultivated arranger growth in both regions while welcoming the inclusion of arrangers from many locales including Japan, South Carolina, Oregon, New Mexico, Washington, and Colorado.
