Our agency has built its foundation on trust, personal service, and a commitment to protecting the people and businesses in our community. We believe insurance should be clear, accessible, and tailored to each client’s needs, not a one-size-fits-all product. That’s why we take the time to listen, understand your goals, and provide guidance that truly fits your life.
With deep roots in our community and years of combined industry expertise, our team works hard to make insurance straightforward and stress-free. We partner with trusted carriers, stay ahead of industry changes, and advocate for our clients every step of the way—from selecting coverage to navigating claims.
We take the time to get to know every individual, family, and business we serve—because understanding your goals helps us protect what matters most to you. Whether it’s safeguarding your home, farm, business, vehicles, crops, or future, we’re committed to delivering solutions that fit your life, not the other way around.
As your local, dedicated insurance professionals, we’re proud to be a resource you can rely on today and for years to come.
Our agency began in March of 1998, as Southeast Nebraska Insurance Agency, Inc (SENIA) with a simple mission: to offer honest, reliable insurance solutions backed by local expertise. For years, it was led with dedication and integrity by our founder, Theodore Godemann—who built strong relationships and a respected reputation throughout the region.
As the agency grew, so did the next generation’s involvement in the business. Eventually, in July of 2023, the agency was purchased from our founder by his son, Trevor Godemann, continuing the family legacy while bringing fresh energy and a modern perspective. This transition preserved the values the agency built on while opening the door to new opportunities, expanded services, and a renewed commitment to our clients.
On January 1, 2026, as our agency continues to expand, welcoming new partners, and expanding our locations, we reached an important milestone: a name that better reflects who we are today and where we’re headed. Katrina Delezene and Cozett Knight joined the business—bringing additional expertise, energy, and a shared commitment to serving clients with excellence. Their involvement represents a new chapter for our agency: one that embraces collaboration, improved service capabilities, and a broader range of solutions for the people we serve. Southeast Nebraska insurance Agency, Inc, is now RiverStone Insurance Group, Inc. Our agency’s headquarters is in Falls City, NE and offers two new locations in Rock Port and Mound City, MO.
Though changes have occurred, our values haven’t. The same people you’ve trusted for years remain here – ready to serve, support, and guide you with the same level of care you’ve always known. We continue to operate on the same principles we were founded on—integrity, personal attention, and long-term support. Many of our clients have been with us for generations, and we’re proud to be a steady presence through life’s changes, challenges, and milestones.
As we look ahead, our vision is centered on growth, innovation, and deeper community impact. We’re committed to expanding our services, adopting new technologies that simplify the insurance experience, and strengthening the relationships that define who we are.
Our future focus includes:
While our agency continues to evolve, one thing remains constant—our dedication to providing dependable, personalized service for every client who walks through our doors.
As an independent agency, we partner with a wide range of carriers to give you flexible options and competitive coverage. From policy selection to claim assistance, our team is here to advocate for you and ensure you feel confident every step of the way.
We’re honored to serve our community and look forward to continuing our tradition of exceptional service for many years to come. Our priority is—and always will be—your peace of mind.
Trevor Godemann began his insurance career in July of 2010 but his passion for helping people started long before that.

Owning his own agency wasn’t just a business move—it was a way to build something rooted in his own values: honesty, service, and treating every client like they’re part of his circle. In the fall of 2025, he decided to bring on two new partners who will help keep the tradition of a small hometown agency where people feel welcome, heard, and supported.
