John W. Muster, IV  78, of Calhoun, Kentucky passed away Wednesday, December 3, 2025 at TriStar Skyline Medical Center in Nashville, Tennessee.  John William Muster, IV was born March 2, 1947 in Calhoun, Kentucky to the late John William ‘Bill’ Muster, III and Claire Marie Gibson Muster.

John's entrepreneurial spirit shone through in 1976 when he and his brother founded Muster Associates, a professional vehicle sales company specializing in ambulances and funeral vehicles, which achieved sales recognition both nationally and internationally.  John loved being able to talk with other funeral professionals, hear both their family heritage and trade stories, and supply them with their professional vehicle needs.  Muster Associates would eventually evolve into Muster Coaches, and the company will continue to supply professional vehicles with the same service to which funeral directors have become accustomed to from John.  At Muster Coaches, one of John’s favorite sales promotions was his annual ‘Run for the Roses’ sales campaign.  Each year, Muster Coaches would draw one lucky customer from that year to receive a trip to the Kentucky Derby with John and his wife, Susan.  John always loved being able to treat funeral professionals from across the nation to a true Kentucky Tradition and even installed several as official ‘Kentucky Colonels.’
