In 1999, three consultants with extensive experience in design and construction of mechanical and electrical systems formed Matrix Consulting Engineers, Inc. in Lansing, Michigan.  The partnership eventually grew to four members and has gained a reputation for excellence.  This reputation has won the team countless projects on some of Michigan's most important buildings and made Matrix a top engineering company.

Why Choose Us

why choose us 1

Our company is small enough to offer our clients the individual attention each project deserves, yet large enough to handle any  size job. A partner is assigned to every  project as the project manager and takes full responsibility for that project from the start of design through completion of construction.

why choose us 2

Our staff is primarily composed of professionals. This means that not only the person leading the project is a graduated professional, but the people working behind the scenes and implementing the design are as well. Their training comes backed with years of experience, ensuring your project both theoretical and practical expertise.
