The Mitten family has had 4 generations on our board of directors to date. The family-owned business still has the same values and practices as we did in 1956. Our once small business has turned into the largest locally owned and operated propane dealer in our area. We service over 2500 customers and we are still growing because of the close ties with the local heating contractors, appliance dealers, and builders.
