History

Glen Leiszler credited his company's success to the simplest and most basic of all business formulas: honesty and hard work. "Treat your customers with respect," he advises. "Be truthful with them. Treat everybody alike. Get the right people helping you." "And after you've done all that, be willing to put 101 percent effort into your business. That's all it takes to have an operation that will grow."
