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 serving his clients and employees. He wanted to create an environment where the two halves of a company would thrive.

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

Today, Cal’s vision is carried on by his daughter Lilly Harris in her role as President and CEO. For Lilly, MSA has always been about family—her parents played pivotal roles in the company for nearly three 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, Hispanic Executive Quarterly Magazine.
