About The Coste Agency

Protecting Long Islanders Since 1948

The Coste Agency is Holbrook’s oldest business. The year we opened our doors, MacArthur Airport had only been around for 6 years; it would be another 8 years until the Sachem School District was established…..and the Long Island Expressway would not get to Holbrook for another 21 years! Our family-run agency was founded by Louise Coste in 1948 and is still being operated by the same family who started it.

We’ve seen many changes over the years and faced many challenges. We have gone from being the only insurance agency in the community, to competing with dozens of “Johnny Come Lately” agencies and companies. Sure, we have to be able to compete with good pricing; we have all that…but we are most proud of the talent in helping our customers get the coverages that are most beneficial to their needs.

Customer Service Above All Else

You can take a chance by calling an 800 number or getting a quote on the Internet. Just remember, the next time you call that number or go online, you won’t be talking to the same person. There is safety and comfort in knowing the people who were there when you made your purchase decisions are there when you call to make changes or file a claim. Stick with people you know, stick with Coste.
