108 YEARS AS A FAMILY OWNED AGENCY

95+ YEARS COMBINED KNOWLEDGE & EXPERIENCE

15+ COMPANIES REPRESENTED

Mongin Insurance is an independent insurance agency. Why is that important to you? Being independent means we have access to a variety of niche insurance companies which allows us the ability to offer you more than just one option. After we listen to your concerns and find out what is important to you, we then build a custom plan that fits your specific needs. Every insurance company is different just like the policies they offer. We understand one size does not fit all. We strongly believe in supporting organizations like CP, Green Bay Habitat for Humanity, Center For Childhood Safety and Green Bay Area Schools!

You deserve the BEST.

We can offer you 95 plus years combined knowledge and experience. We review hundreds of policies every year. We are the longest running family owned insurance agency in Green Bay. Our team takes the concerns of our customers and their families very seriously, because we care. Our hope is for you to feel like part of our family.

“Family is important to you, and protecting yours is important to us.” -Team Mongin
