Inszone Insurance Services Expands Montana Presence with Streeter Brothers Acquisition

Inszone Insurance Services has expanded its presence in Montana through the acquisition of Streeter Brothers Insurance, a long-established agency based in Billings. The move reflects Inszone’s continued growth strategy and its focus on partnering with community-based agencies.

Streeter Brothers Insurance was founded in 1922 by Delton and Delbert Streeter. The agency has served the Billings community for more than 100 years and has built a reputation for trusted guidance, personal service, and strong local relationships. Over time, the business has transitioned through multiple generations of ownership while maintaining its commitment to clients.

Most recently, Linda Schmaing owned the agency. She began her career with Streeter Brothers in 1986 and purchased the business in 2016 after more than 30 years of leadership and service. During her ownership, the agency continued to operate as a full-service, generalist firm. It provides personal, commercial, and life insurance solutions to individuals and businesses throughout the region.

Schmaing said continuity played a key role in her decision. “After careful consideration, Inszone felt like the best fit for me, my team, and our clients,” she said. She emphasized the importance of keeping staff in place, remaining in the same location, and maintaining the level of service clients expect. She also noted that Inszone supports a thoughtful transition as she plans for retirement.

As part of the acquisition, Streeter Brothers Insurance will continue operating from its current Billings office. The existing team will remain in place to ensure a seamless client experience. In addition, the agency will gain access to Inszone’s expanded carrier relationships, technology platforms, and operational resources while preserving its local presence.

Chris Walters, CEO of Inszone Insurance Services, highlighted the significance of the partnership. “We are honored to welcome Streeter Brothers Insurance to Inszone,” Walters said. He pointed to the agency’s more than 100-year history in the Billings community and its reputation for professionalism and client commitment. He added that Inszone looks forward to supporting the team and its clients with additional resources.

The acquisition strengthens Inszone’s footprint in Montana. It also reflects the company’s broader approach to growth through partnerships with established, community-focused agencies across the country.

Inszone Insurance Services was founded in 2002 and is headquartered in Sacramento, California. The company operates as a full-service insurance brokerage firm offering property and casualty and employee benefits solutions. It continues to expand both organically and through acquisitions. Inszone currently serves clients through offices in California, Arizona, Arkansas, Colorado, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Missouri, Montana, Nebraska, Nevada, New Mexico, Oklahoma, Oregon, South Dakota, Texas, Utah, and Washington, with additional nationwide expansion planned.
