There are 3 reasons I would choose Duncan Insurances over a larger venue. First, Dave did such a thorough job in finding us all the possible discounts we could get, such as using my husband’s Geology degree for a "scientist" discount. I know we are getting the best possible deal out there. Second, he’s easily reachable & readily available to respond to all our questions, and gave us some good advice regarding a recent traffic ticket I had. Finally, I like dealing with a "live" person who answers the phone when I call, instead of getting one of those ridiculous phone-trees where I have to press 5 numbers before getting a live person. Overall, it’s the personable, quality service I receive, as well as being treated as a valued customer that will make me stay with Duncan Insurance Services for the long-haul.
