The two, in collaboration, have proven to be successful in handling even the most complex insurance and real estate situations. They provide all types of insurance and real estate needs, whatever the customer may be looking for.

   In 2006, Seigfreid Agency became a third-generation enterprise, after their daughter Amanda joined the team as a licensed insurance agent and real estate agent, And became a real estate broker in 2020.

     In 2018, Seigfreid Agency welcomed their son Erik Seigfreid into the family business. The family brings together almost a century of Sidney-area knowledge and business expertise, and they are proud to serve their Sidney and North Eastern Montana neighbors.
