Hiring on in 1981 and working in the Kalamazoo/Portage market since 1993, he is the Kalamazoo office regional survey manager where he coordinates day-to-day department operations, coaches team members, promotes client relationships and business development, and works on large-scale utility, municipal, and commercial projects. Exceptional at details and implementing project schedules, Gary’s efficiency and cost-effective methods have proven invaluable to his clients. Outside the office, Gary serves as Kalamazoo County Surveyor – a position to which he was elected in 2008 – and is the Kalamazoo County representative for the State’s remonumentation program.
