Our story

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.

"We will never recommend something for you unless we truly believe it is in your best interest."
Our story
Why an independent agent

One call. Many carriers. Someone who picks up.

A captive agent can only sell one company. We shop the market for you, explain the trade-offs, and handle the paperwork when life changes.

Local Service, Multi-State Protection

We may be based in Kings Park, but our reach extends far beyond Long Island. We write policies across New York and multiple states, offering the seamless, personal service of a neighborhood agency wherever life or business takes you.

01

Tell us what you need to protect

A quick call or a short form. We ask the questions that actually change your price.

02

We compare carriers for you

Partner and brokered markets, side by side, with a straight recommendation.

03

We stay on your side

Policy changes, renewals and claims go through people you know, not a call center.
