For the past 26 years, Lonni has shared her life with her husband, Cory, and raised two wonderful children, Dawson and Micah. Outside of work, she finds joy in traveling, reading, boating, and cooking, especially when it means spending quality time with family and friends.
She grew up north of Aberdeen, South Dakota, on a dairy farm, where hard work wasn’t just expected, it was a way of life. “Farm life taught me that it didn’t matter who you were, how old you were, or whether you were a boy or a girl; everyone did chores. The day wasn’t done until the work was truly finished.” Whether she was baking with her mom and grandma or fixing machinery alongside her dad, she learned the value of grit, problem-solving, and the importance of failing forward. Those lessons, shared with her three sisters, shaped her into the determined and hands-on leader she is today.
What motivates her? Progress. “I love taking something good and shaping it into something great. Everyone wants to be part of an excellence-driven organization.” At Interstate Engineering, she’s found just that. “Our team is humble, hungry, and smart. We get to share our talents in the communities we call home—and that’s incredibly rewarding.”
With over 26 years in the industry, she brings a well-rounded understanding of both private and public infrastructure needs. Lonni has a passion for creating solutions that fulfill the success metrics of all stakeholders, with project costs being managed as the highest priority. As principal in charge, Lonni assures that all stakeholders’ perspectives are reflected through a thoughtful, innovative, and high-quality design.

Her experience spans all stages of project development, including planning, funding assistance, design, construction engineering, contract administration, funding administration, and surveying.
