John Walker

APOC Field Systems Coordinator


John Walker has earned respect by doing, but he is well credentialed too. At Joliet Junior College, John earned certifications in roof repair, boiler maintenance and basic building electrical systems. He has been a casino maintenance supervisor and owned and operated a residential maintenance and remodeling company. John continued to support the construction segment as an assistant manager at a building supply house specializing in roofing, siding, windows and doors. He then turned his focus to coatings, first as an independent sales rep for a national coatings company, then as a site supervisor for roofing contractors overseeing the installation of more than one million square feet of cool roof coatings. Interestingly, John was also at one time a paramedic firefighter. John celebrated his ten year anniversary with APOC, also in February of this year.
