who we are

In 2004, James Kosner founded JIMAX Landscape, a residential landscaping company based in Downers Grove, IL. JIMAX was relocated to Peoria, IL in 2007, where he graduated Dunlap High School. From there he attended Illinois State University where he studied Building Construction Management. In 2013 JIMAX Landscape was converted to JIMAX Landscape LLC when James partnered with Jarrod Martis, our vice-president. In addition to overseeing JIMAX Landscape, Martis is our expert in-house mechanic and regularly uses knowledge gained at the University of Illinois, where he studied mechanical engineering and has performed agricultural research in conjunction with UIUC and the USDA.

JIMAX continues to grow through acquisition of commercial accounts, working with local builders, performing more in-house work, and growing our relationships with the communities. We continually invest in new equipment, technology, and landscape techniques to better serve our customers and look forward to continued improvement in the future. JIMAX is the only company or municipality in Central Illinois to invest in the Trimble Technology Weedseeker Selective Spray Technology. JIMAX also owns and operates a Perma Green Ride ON Sprayer Spreader. JIMAX Landscape LLC maintains a Drug Free Workplace through pre-employment screens as well as randomized testing through MEDTOX Laboratories. Safety training is emphasized at the beginning of each season with several days dedicated to review and implementation and meetings are conducted weekly by the crew chiefs with their crews to reiterate these points.
