Our story

A Main Street agency, four generations in.

John J. Flynn, Inc. has served the Kings Park community and beyond since the 1930s. We are an independent agency representing many AM Best "A" rated carriers known for excellent service and rates.

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.

"We will never recommend something for you unless we truly believe it is in your best interest."

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 office, statewide reach

Our office is on Main Street in Kings Park, and we write policies for clients in New York City, across Long Island and upstate. Wherever you are, you get the same people and the same phone number.

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.
