Superior Insurance Services

Covering approximately 4 counties in northern and central New York, A.T. Matthews and Dier is an independent insurance agency specializing in property and casualty insurance for both individuals and businesses.

We currently operate 2 agencies in Jefferson County under the approved trade names of A. T. Matthews and Dier, located in Watertown, NY, and Timerman Adams Agency in Chaumont, NY.

A.T. Matthews and Dier, a 3rd-generation, family owned business, provides a higher level of service than the competition. We offer over 30 years of experience and more than 100 years of combined experience.

Growing Over the Past Decade

In April of 2000, we purchased a long-established insurance agency in Watertown called A.T. Matthews & Son Inc. As the agency grew, more insurance carriers were added to the lineup of companies available and we were able to offer our customers more viable options. 

In the summer of 2009, the Timerman Adams Agency was purchased when a long-term associate, Jerry Adams, retired and sold his book to Douglas Dier. 

Today, the agency continues to grow and reach customers throughout northern and central New York.

Fast and Efficient Service

For the past 14 years, we have operated in a “paperless” environment, where we can offer real-time service to clients and do it quickly, accurately, and effectively. 

Our digital access allows us to provide a higher level of service with much greater transactional efficiency in document storage, retrieval, and file notation.

Like all our agency objectives, automation is a part of the means by which we strive to provide our customers with better overall service. 

Through the years, we have worked to develop excellence in all areas of our agency operation. Our service goals and objectives have guided our initiative and are the premise from which we looked to top our competition.

Updated Systems Protect Your Data

In February of 2008, we enhanced our document management and retrieval ability with a new and upgraded agency management system called AMS 360 online. 

Our system provides for easier indexing, additional storage, and faster retrieval of scanned and electronic images. It is backed up at an off-site location by Vertafore, the parent company of AMS 360.

Electronic Manuals Improve Service

A.T. Matthews and Dier has gone to great lengths to standardize our workflow and to establish comprehensive procedures and practices.

Standardized, interactive electronic manuals assist us in our daily operations and also give us a format for initial training of new employees.

They are our constant reference tool and provide us with quick and accurate information that let us serve you better.
