“We have always been in the service business but when Linc approached us with the model of selling proactive maintenance agreements, we were hooked. The decision to purchase a Linc franchise is the best decision we have made in the 104 year history of our family owned business.” - Mark W. Thompson, President , H.A. Thompson & Sons
