^{Who we are}About Our Mission

What Drives us

We built this firm on the belief that good financial advice starts with listening. Since 2005, we've worked with individuals and families across the United States— including those in agriculture, all with their own goals and concerns. Our approach is straightforward: understand what matters to you, create a plan that makes sense, and stay with you as life changes.

What guides us

Our Core Values shape every decision we make, and our reputation depends on living them daily.

Professional integrity

Openness and honesty are the foundation of our business. We maintain high ethical standards in everything we do because, for us, success without integrity is total failure.

Client Satisfaction

You deserve excellent service, and we settle for nothing less. Clients are the foundation of our business, and we go to great lengths to provide a prompt and courteous response to every inquiry.

Community Involvement

We invest in our community because we understand the relationship between its success and ours. Whether through service to youth or support for local initiatives, giving back isn't separate from our work—it's central to it.

Our Foundation

Founder Aaron Broz, a CERTIFIED FINANCIAL PLANNER™ professional, started MNB Investments with a simple commitment—to provide honest, dependable advice rooted in the values that define this community.

I grew up in Hayes Center, a small Nebraska town where the community genuinely supports its youth. I was blessed to grow up there, and I still call it home today. That sense of looking out for one another shaped how I think about my work—it's not just about investments and returns, it's about helping people build something solid for themselves and their families.

I've been in financial planning for 25 years and earned my CFP^® certification in 2008. I've always been fascinated by investments, but what really drew me to this career was the people—that's what keeps me going. I genuinely enjoy talking with my clients, and the feeling of appreciation I get from helping someone reach their goals is unmatched. Everyone deserves someone in their corner who's looking out for their best interests.

Outside the office, my life revolves around my family—my wife Britni and our three kids: Ashlin, Aubrey, and Kade. They're everything to me and my reason for working as hard as I possibly can. When I'm not meeting with clients, you'll find me outdoors helping on the farm or supporting 4-H and the McCook Optimist Club, giving back to the community that's given so much to me.

I've been with MNB Investments since May 1992, and over those years, I've seen firsthand what good client relationships look like. My role is to support Aaron Broz and make sure our clients get the attention and service they deserve. Whether that's addressing service needs, preparing and processing new business, or providing ongoing support, I work to keep things running smoothly behind the scenes.

What I enjoy most about this work is being part of a team that genuinely cares about the people we serve. It's rewarding to know that the details I handle help our clients feel confident and well taken care of.
