In 1949, two hard-working Midwesterners – John Bolton and Martin Menk – saw people in their surrounding communities with dreams of a bright future, a desire to grow, and a common challenge of aging infrastructure. Their goal: to help communities make progress by listening to what people want, finding the best solutions for their needs, and treating them right. The legacy of John and Martin lives on. We still want to help, we work hard every day, and we always remember what got us here – we’re people helping people. Today, Bolton & Menk, Inc. has more than 700 employees including a professional staff of more than 200 engineers, planners, landscape architects, and surveyors.

Bolton & Menk specializes in providing public infrastructure solutions. We want to take care of our clients by providing the best services and solutions for them. From advocating for our communities, to designing their dreams, to finding funding; we take pride in our work because we live in these same communities. We believe in the power of face-to-face meetings, friendly conversations, and a collaborative decision making process to keep your projects on schedule, within budget, and focused on real, workable solutions. 

We promise every client two things: we’ll work hard for you and we’ll do a good job. We take a personal interest in the work being done around us. And at the end of the day, we’re Real People offering Real Solutions.
