    Once in a while a business deserves a BIG pat on the back when it exceeds what is expected in regards to services rendered… That business is Davis Oil of Keene NH!! From the first encounter with Dick and Jane Walsh back in the 60’s, we have had nothing but terrific and timely responses for oil delivery or for any problems that might have arisen. at our business or residence …. It’s not often that a family can continue to carry on the traditions that built a company into the successful one that Davis Oil is …. But … we have that same confidence with Peter and Steven Walsh and Dixie Cote at the helm as we did so many years ago. Well Done!! Keep up the good work!
