Entegra Systems



Dean Johnson

President & Founder

Dean Johnson leveraged 25 years of experience in the systems and defense industries to found Entegra Systems. Basically, he wanted to create the kind of company that he would want to work for — one that had an open door with leadership; embraced diverse skill sets and technical disciplines; offered great benefits and work environment; and was involved in vitally important, meaningful work. And that’s what he did.

Dean’s areas of expertise include business and technical management, systems research, architecture, requirements, system and software engineering, development, and testing. Prior to founding Entegra, he worked at The Boeing Company, Conquest, Inc., ManTech, and Booz Allen Hamilton.

Dean holds an M.S. in Electrical Engineering, with a concentration in Telecommunications, from The Johns Hopkins University, and a B.S. in Computer Engineering, with honors, from Clemson University.

She is highly regarded for her strategic thinking, people management skills, attention to detail, presentation skills, and overall management talent.

Brian Mallare

Vice President

It’s probably not a coincidence that, like Entegra Founder Dean Johnson, Brian Mallare also worked at The Boeing Company, Conquest, Inc., and Booz Allen Hamilton. Good talent tends to stick together. In addition to his roles as a civilian contractor, Brian also served as a Captain in the U.S. Army.

Brian brings deep systems engineering and program management experience — 30 years’ worth — to the table, in the intelligence and technology markets, public and private sectors. He plays vital systems engineering and project leadership roles at Entegra, offering invaluable technical contributions to every team he’s on.

Brian holds an M.A. in Business Management from Central Michigan University, and a B.S. in Electrical Engineering from Clarkson University.
