A Main Street agency, family-run for generations.
John J. Flynn, Inc. has served the Kings Park community and beyond for generations. We are an independent insurance agency representing many AM Best "A" rated carriers, chosen for their financial strength and claims service.
Today JN Grace Group, Inc. and the Flynn Insurance Agency work from one office at 8 Main Street, with the fourth generation of Flynns on the horizon.
When you call, a real person at our Main Street office picks up. No phone trees and no runaround, just neighbors who know your policy and will walk you through it.
