Board of Directors

Lonni Fleck, PE
Growing up, Lonni often took things apart, figured out how they worked, and then put them back together. And though dismantling was entertaining, bringing everything together was where she found the most enjoyment. Her problem-solving ability, love of math, and understanding that investments should have returns led Lonni to a civil engineering career. With over 20 years in the field, Lonni has worked with clients, helping solve infrastructure and utility challenges, including designing the dream, helping find funding, and watching the goal built into a reality to make communities stronger and serve people better. In 2009, Lonni was appointed to the Interstate Engineering Board of Directors. She uses her abilities to bring people together to lead and grow the firm as it prepares for its next 40 years.
“Lasting relationships matter most, whether with clients, coworkers, or peers. I want to see our company be where clients and team members feel welcome and supported.”
