August 31, 1983 was the beginning of a long term success story. Donald and Bonnie Sullivan opened an insurance agency by the name of Administrative Safety Services, Inc. in Roseville, Minnesota with their first employee being their daughter, Lisa (Sullivan) Burnside. The vision then was to be a comprehensive company supplying insurance and related services to the public.

By 1984, Donald and Bonnie had changed the focus of the agency from general insurance to insuring the transportation industry. They made this commitment, due to the complexity of the transportation industry and its special insuring needs. Over the next few years, the agency released accounts that did not fall under the category, yet grew significantly in the number and size of accounts written. To assist in this endeavor, their son, Shawn Sullivan, joined them as a valuable salesperson in 1984 with Michael O'Neil, their nephew, following in 1987.

Their daughter, Kimberly (Sullivan) Schwartz joined the agency in 1987 to provide profitable financial results.

The agency name was changed on October 26, 1989 to Minnesota Truck Writers, Inc. This provided a better understanding of the agency's unique focus on providing transportation insurance.

On January 1, 1996, the Sullivan family purchased Ringnell Insurance in Welcome, Minnesota. This agency is now called Administrative Risk Consultants, Inc. DBA: Truck Writers. The two agencies share the focus on the transportation industry by providing quality services.

In 2005, Truck Writers launched BOSS Insurance Group for general business, life, health, and personal lines.

In 2008, Truck Writers purchased MacKenzie Agency – a well established truck, general business, and personal lines agency in St. Peter, Minnesota.
