Who We Are

Who the Coste Insurance Agency is

The Coste Agency, Inc. is a family owned and operated insurance agency founded in 1948 by Louise Coste. Fred Coste is presently the second generation owner of the agency.

We sell and service the personal and commercial insurance needs of Holbrook and surrounding communities. With competitive rates and many insurance companies to choose from, our customers can be assured of getting the best rates for their auto, home, and business insurance.

Do you have extra special toys? ATV’s, snowmobile’s, boats and airplanes are no problem either! If you don’t see the information you need on our website, please give us a call, so that we can help you get the coverage you need.

We are an Independent Insurance Agency

We do not work for an insurance company, we work for you. We work on your side when you have a loss and follow through to see that you get fair, prompt payment and service.
