The Agency was established in April 1961 by owners Kay Carpenter and William Seitz as a small corporation called The Carpenter-Seitz Agency and served mostly rural customers in Eastern Montana by providing cost-effective insurance. With the retirement of Kay Carpenter in 1976, the business was purchased by William Seitz. Today, the Agency is led by John Seitz and David Seitz, who continue its tradition of excellence established by its founders.
As an independent agency, Seitz Insurance represents over 30 insurance companies and an expanding client base throughout Montana, North Dakota, Wyoming, and Colorado. Our qualified team of professionals has over 150 years of combined experience in the insurance industry and takes pride in providing consistent, professional service to our broad base of customers, including businesses, farm and ranch operations, and home and automobile owners.
