Grenier Public Insurance Adjusters: Helping property owners for over 40 years. Licensed and insured to assist throughout MA and CT

After attending Nichols College, John Grenier started his career with General Adjustment Bureau in the 1960’s where he learned the insurance business from a corporate perspective.  In 1973, John left his corporate job to start Grenier Public Insurance Adjusters.  He saw an opportunity to own and operate a business that helped people when they needed it most.  John's vision was to provide for his own growing family while helping others.  More than 40 years later, John is still advocating for property owners and has helped resolve $100mil+ in claims.  He is proud to have built a business based on honesty and integrity, and is an active member of his community as well as a member of the Massachusetts Association of Public Adjusters.

Justin Grenier is the second generation to join Grenier Public Insurance Adjusters.  In addition to studying Business Administration at CCRI, he joined the Union of Bricklayers and Allied Craftworkers and worked as a mason for 12 years before joining GPA in 2008. Once joining the family business, he quickly established himself as a leader in the industry handling $10mil+ in claims. Justin is also a member of the Massachusetts Association of Public Insurance Adjusters, and when not working he enjoys the outdoors and spending time with his wife and new daughter Skylar.

“Back a few years ago I experienced a large water loss at my home in Weston. The first person that was sent out by my insurance company told me verbally my claim was around $150,000 which I thought was extremely low so I called Justin for his assistance. I was very pleased at how efficient and knowledgeable he was. I certainly didn't expect getting 3 times the settlement the insurance company offered. I plan on referring him to anyone who has a loss. He did a great job !!”
