About Us


picQuadrex Aviation, LLC was established in February 2007 as a reorganization of Quadrex Associates, Inc. which was formed in early 2000. Based in Melbourne, Florida, the origins of Quadrex were based in the progressively diversified and unique project experience of the firm's principal, Dr. Dave Byers. Dave has 30+ years of experience in airport facility development, environmental analysis, and strategic business planning.

Much of Dr. Byers' early background was formed serving as an airport planner for a number of national airport consulting firms. Midway in his career, he was invited by one of his clients to form his own planning practice and D.A. Byers & Associates, Inc., was founded in 1992. Except for a brief stint with a major architectural firm in the mid-1990s, Dave has kept his practice active, serving a multitude of clients with challenging assignments. Today, Quadrex Aviation serves as Dr. Byers' vehicle for providing a wide range of airport consulting services to the airport management professionals leading commercial service and general aviation airports.
