"We have done business for many years with Gilman Electric and have always been very satisfied with their service. From the management to the delivery drivers, we have never had any issues. Their delivery schedule is probably the best in our area. The majority of our business is done over the telephone but we always enjoy stopping by the local branch and more often than not, come out with some great gadgets or tools they may currently have on sale. We would highly recommend Gilman Electric to anyone that is in the market for electrical needs."
