Inszone expands with Streeter Brothers acquisition

Inszone Insurance  has acquired Streeter Brothers Insurance, a Billings, Montana-based agency with more than 100 years of history. Terms of the deal were not disclosed.

Founded in 1922, Streeter Brothers operates as a full-service agency offering personal, commercial, and life insurance, and was most recently owned by Linda Schmaing. The agency will continue operating from its current location with its existing team, while gaining access to Inszone’s carrier relationships, technology, and operational support.

The acquisition strengthens Inszone’s presence in Montana and is part of its broader strategy to grow through partnerships with established, community-focused agencies.
