Mahler spent over 40 years in concrete construction - he still worked, until quite recently, as a civil engineer, cement finisher and contractor for Classic Concrete Designs, based in Overland Park, Kansas. They specialised in concrete repair as well as masonry and constructing countertops. John himself lives in nearby Missouri. Mahler raced for some time in USAC events, but never quite achieved the success that his initial promise showed.
