U S Coast Guard Auxiliary Announces Command Staff

2-7-2026 – The Prairie du Chien Flotilla, US Coast Guard Auxiliary has announced its new command staff for 2026.

Arthur Sullivan of Elkport, Iowa has relieved Sue Tiller as Flotilla Commander while Flotilla Vice Commander Joanie Dickerson of Bagley, Wisconsin will continue to serve in that position for 2026.

 Dickerson is a retired US Navy Chief Petty Officer and retired teacher from St Mary’s Catholic School in Bloomington, Wisconsin. She has previously served as Vice Commander and is the Flotilla Public Education and Navigation Aids Staff Officer.

Sullivan is a former US Navy submarine Petty Officer and retired law enforcement officer. He has previously served as Flotilla Vice Commander, Flotilla Commander, and is also the Flotilla Training and Public Affairs Staff Officer.

Tiller is a retired US Army Major and retired owner/operator of Tiller Furniture in Prairie du Chien, Wisconsin. She has completed her two years as Flotilla Commander.

The Commander and Vice Commander are elected positions with term limits of two consecutive years.

Sullivan said, “The major challenge facing the Flotilla for 2026 is recruitment. The US Coast Guard Auxiliary is the all-volunteer civilian component of the United States Coast Guard. We rely on dedicated volunteers who are active and willing to work and train hard to provide much needed education and safety services to the boating public. Prior military or public safety service is not required.”
