Audio By Carbonatix

SACRAMENTO, Calif.--(BUSINESS WIRE)--Mar 19, 2026--

Inszone Insurance Services, a rapidly growing national provider of commercial, personal, and benefits insurance, is pleased to announce the acquisition of Streeter Brothers Insurance, a long-established insurance agency based in Billings.

Founded in 1922 by Delton and Delbert Streeter, Streeter Brothers Insurance has proudly served the Billings community for more than a century. Over its long history, the agency has operated through multiple generations of ownership while maintaining a strong reputation for trusted guidance, personal service, and deep local relationships.

The agency was most recently owned by Linda Schmaing, who began her career with Streeter Brothers in 1986 and purchased the agency in 2016 after more than 30 years of leadership and service. Under her ownership, Streeter Brothers has continued to operate as a full-service, generalist agency offering personal, commercial, and life insurance solutions to individuals and businesses throughout the region.

“After careful consideration, Inszone felt like the best fit for me, my team, and our clients,” said 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.”

As part of the acquisition, Streeter Brothers Insurance will continue operating from its current Billings location, with the existing team remaining in place to ensure a seamless experience for clients. The agency will gain access to Inszone’s expanded carrier relationships, technology platforms, and operational resources while maintaining its strong local presence.

“We are honored to welcome Streeter Brothers Insurance to Inszone,” said Chris Walters, CEO of Inszone Insurance Services. “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.”

This acquisition further strengthens Inszone’s footprint in Montana and reflects the company’s ongoing commitment to partnering with respected, community-focused agencies across the country.
