Mark’s Quality Marine was started in 1997 by Mark and Donna Grahn.  Like many new business’s it started out small, with just a bait shop.  The Grahn’s re-invested every extra nickel into their growing marina.  They put up several large aluminum buildings for Winter Storage and added on to the existing Bait Shop in 2006.  That gave them the area’s only Enclosed Showroom so customers can view Fishing Boats, Bass Boats  and Pontoon Boats out of the Wisconsin weather.

The Grahn’s run a customer driven company that is always evolving in the ever changing marine business.  Mark and Donna’s children Sunnie J. and Mark Jr. even participate in the family business, doing commercials and advertising in local papers.  Their plan is to grow with the times and always be open to serve the wonderful communities of Wautoma and Big Flats Wisconsin. Mark, Donna, Sunnie and Mark Jr. would like to Sincerely Thank You for Your Business!
