About Stonewall Insurance Group Inc.

Insurance without the hassle

Nowadays, customer service seems to have become a thing of the past for many businesses, especially in the insurance industry. Here at Stonewall Insurance Group, we fight that narrative.

We’re car enthusiasts who focus on providing our customers with the best possible insurance experience, from start to finish.

The best coverage. The best service. The best price.

How it works

Custom Policies

A one-size-fits-all policy really doesn’t fit anyone. That’s why we tailor each and every policy to your specific needs. We’ll make sure you’re adequately covered and not paying for things you don’t need.


Stonewall Insurance Group was built to be a one-stop shop for all of your insurance needs. We can insure all of your VehiclesBusinessesProperties, and more. The best part is that when you bundle your policies with us, we can save you up to 25%

We're on Your Side

Being an independent insurance agency, we work with the top insurance companies without being tied to one. This means that we can shop around to find you the best coverage for the best price. If a better deal comes up later on, we’ll notify you so you never miss out.

The best coverage, the best service, the best price

We’ll take care of your insurance, so you can focus on what’s important.

Our History

Back in 1988, Jeff DeMarey was helping out his father’s insurance agency when he saw a pattern of big box stores putting small mom-and-pop shops out of business. He watched as companies like CVS, and Home Depot took out their local competitors and he realized it was only a matter of time before the same was done in insurance. In hopes of fighting this, he started looking for a niche to specialize in and naturally, being a car enthusiast, he landed on classic and collector car insurance. Over the next 15-20 years, he was able to grow the agency to over 3,500 policies, finding new ways to automate and streamline the insurance process along the way.

In 2008, he decided to branch out and start Stonewall Insurance Group, a friendly agency where his customers can get the best service, the best coverage, and the best price. Today, almost 20 years later, Stonewall still specializes in classic and collector cars, and is able to write insurance for all types of assets, in any of the 50 states.
