John Grenier

After attending Nichols College, John Grenier started his career with General Adjustment Bureau in the 1960s 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.
