Background of Streeter Brothers Insurance
Streeter Brothers Insurance was founded in 1922 by Delton and Delbert Streeter and has operated continuously in the Billings community for over a century. The agency has transitioned through multiple generations of ownership while maintaining a consistent operational model centered on client relationships and local engagement.
Over its history, the agency has developed a reputation for providing trusted guidance, personalized service, and maintaining long-standing client relationships within the region. Its operations have been structured around serving both individual and business clients with a range of insurance products tailored to local needs.
The agency’s longevity reflects its continued role within the community as a provider of insurance services across changing market conditions and ownership structures.
Leadership and Ownership Transition
Linda Schmaing, the most recent owner of Streeter Brothers Insurance, has been associated with the agency for several decades. She began her career with the agency in 1986 and later assumed ownership in 2016, following more than 30 years of involvement in its operations.
Under her leadership, the agency continued to function as a full-service, generalist insurance provider, maintaining its established service model and client base. The transition to Inszone Insurance Services reflects a planned ownership change aligned with her future plans.
“After careful consideration, Inszone felt like the best fit for me, my team, and our clients,” said Linda Schmaing. “Continuity was incredibly important to me—keeping our staff in place, staying in our location, and ensuring our clients continue to receive the service they expect. Inszone aligns with those priorities and supports a thoughtful transition as I begin planning for retirement.”
Integration and Operational Continuity
As part of the acquisition, Streeter Brothers Insurance will continue to operate from its current location in Billings, with the existing team remaining in place. This approach is intended to ensure continuity for clients and maintain the agency’s established service model.
The integration will provide the agency with access to:
- Expanded carrier relationships
- Technology platforms
- Operational support resources
These additions are expected to support the agency’s ongoing operations while maintaining its local presence and service approach.
Inszone indicated that the integration model prioritizes maintaining the identity and operational continuity of acquired agencies while providing additional infrastructure support.
Strategic Expansion in Montana
The acquisition of Streeter Brothers Insurance represents a continued expansion of Inszone Insurance Services’ presence in Montana. The company has pursued growth through both organic expansion and strategic acquisitions, focusing on agencies with established community relationships.
By adding a long-standing agency in Billings, Inszone strengthens its footprint in the region and expands its ability to serve clients across the state. The acquisition reflects the company’s ongoing approach of integrating agencies that have demonstrated consistent service delivery and local engagement.
Inszone noted that the addition of Streeter Brothers Insurance aligns with its broader strategy of building a network of agencies that maintain local expertise while benefiting from shared resources.
Leadership Perspective
Chris Walters, Chief Executive Officer of Inszone Insurance Services, commented on the acquisition and the addition of Streeter Brothers Insurance to the company’s network.
“We are honored to welcome Streeter Brothers Insurance to Inszone,” said Chris Walters. “With more than 100 years of history in the Billings community, this agency represents the kind of legacy, professionalism, and client commitment we deeply value. Linda has built an outstanding organization, and we’re excited to support her team and clients with additional resources for the future.”
The statement reflects Inszone’s focus on integrating agencies with established operational histories and maintaining continuity for both employees and clients.
