Who is MNA?

From its inception and establishment in 1959, Mussett Nicholas Associates has set a standard of excellence in consulting services. During the past 61 years, MNA has continued to serve the community, the state, and the international market with the same dedication and integrity that was envisioned by our company’s founders.

Our consistency in providing customized, professional services has earned us a high reputation with our clients, such that 90% of our annual business derives from those we have served in the past.

As times and the needs of our clients evolve, MNA continues its tradition of broadening the range of services we can provide.

MNA is staffed with over 50 employees. This is a highly professional staff with 53% of our engineering and architectural workforce having a professional status. It is a large number to produce multiple projects of a large scope, yet small enough to offer personal attention to the project’s details.

MNA is licensed in over 10 states and has an in-house staff of over 30 mechanical/electrical engineers and five architects. Our staff also includes five LEED accredited professionals.

Examples of the clients we have provided services for:

  • Cummins
  • Eli Lilly & Company
  • Caterpillar
  • Baxter Pharmaceuticals
  • Allison Transmission
  • Cook Pharmica
  • Rolls Royce
  • CSL Behring
  • Indiana University
  • Purdue University
  • University of Notre Dame

The principal owners of the company actively work on each project. Therefore, you get their involved experience and knowledge throughout the duration of your work.

What is right is defined by you, the owner. Individuals at MNA do not impose their personal design goals at the expense of the Owner’s needs or expressed interests. Our ability to listen while providing technical information and the interjection of our suggestions, we believe, has garnered the respect of our clients with whom we have collaborated on previous projects.

As you look to the future, be assured that MNA will fulfill your consulting needs with the same dedication and expertise that all our clients have come to expect and trust.
