I met Sheldon Kahan back in 1998, when I worked for a large residential developer. We developed our relationship that day in 1998 and have done business together ever since then. I have purchased various materials over the years from Interstate + Lakeland Lumber and have always been very satisfied with their sales force, delivery schedules and quality of materials. I consider Interstate + Lakeland Lumber a true Trade Partner.
