Founded in 1941 by mechanical engineer Chauncey M. Buck, CM Buck & Associates, Inc. has expanded from Indianapolis roots to serve the Midwest market at large. Nearly eight decades after the company’s inception, we’re proud to carry on Chauncey’s legacy of superior technical and engineering support for our project partners.

CM Buck’s power and lighting divisions were established in 1953 by Denton E. Hall, an electrical engineer with a major in illumination, leading to the philosophy for the future of the company that remains in place to this day: Regardless of how diversified CM Buck becomes, we’ll continue to specialize in every aspect of our various divisions, assuring our clients receive the highest level of service and support.

By continuing this tradition of innovation and specialization, CM Buck & Associates, Inc. is positioned on the cutting edge of future technologies while retaining our small-town, family-owned roots.
