Everyone on the JBYS team has a long-lived and true love for the water and the recreation it brings. We understand what our customers want, need and desire and take great pride in delivering it.

President Greg Krueger set the tone for his team’s customer care dedication when he started at Jefferson Beach as a sales person in 1970, and worked his way to the top becoming #1 in sales within six months. Greg and his team continue to be a top boating resource more than four decades later, sustaining the reputation as the most trusted place to purchase or sell your boat.

Greg is a 3rd generation boating industry veteran and his experience spans a lifetime. He enjoyed his very first boat at the ripe age of five and was operating his own outboard by age six. Greg has spent his life exploring and enjoying every inch of the Great Lakes which he continues to do today. In addition to sales, Greg has also worked in boat building. He started building center console vessels in 1982 and formed American International, which later sold to Genmar Industries. Greg has served on the Board of Directors for the Michigan Boating Industry Association for over 25 years, and pioneered the establishment of the Recreational Boating Industry Education Foundation in the mid 1980’s with the goal of building a better future for the industry. The Foundation continues to exist, offering educational opportunities to young men and women pursuing careers in boating.
