Meet the Family Behind MSA 

Harris Family
Lilly Harris

Every company needs a vision to guide its growth, its success and its mission. From the beginning, Man- Machine Systems Assessment has been inspired by the concept of family and leaving the world a better place.

Cal Harris started MSA in 1990 after a long career in the Navy and more than ten years as a consultant working with government contractors. He believed in service to his clients and to his employees and wanted to create an environment where the two halves of a company would thrive.

MSA has grown strategically over the years, focusing on agile client service and building a solid foundation for its employees. Low turnover rates ensure that our clients receive unfaltering, exceptional service from the MSA team. We seek opportunities to work with new clients and partners, but we take pride in the fact that so much of our business comes from established client relationships.

Today, Cal’s vision is carried on by Lilly Harris in her role as President and CEO. For Lilly, MSA has always been about family—both of her parents played pivotal roles in the company over the last two decades.

Lilly has worn many hats at MSA, serving as marketing director, HR director, chief financial officer and executive vice president. Since taking the reins in 2008, she has expanded MSA’s core offerings, increased revenue, and streamlined operations.

“What started as a small dream has evolved into an industry leader, dedicated to customer satisfaction by investing in the creativity and ingenuity of its employees…” – Lilly Harris, HEQ Magazine.
