Mark W. Exner began his career in the cleaning industry in 1974. While working towards a degree in law enforcement, he took a job in a hospital environmental services department. Performing all tasks from commode cleaning to sterilizing surgical rooms, Mark found the work hard but very rewarding. Unable to find a job opening in law enforcement, Mark continued to clean and eventually started his own cleaning business.
Shortly after that, Mark took some professional courses on cleaning just to see what he might not know about cleaning. His instructor amazed him on all the many important elements he had never been taught before, and he soon realized just how valuable the knowledge really was. He quickly learned the value of a formal education in cleaning and realized that if the knowledge could help him that much, then he would like to instruct and inspire others, as well.
Currently, Mark instructs CMI’s Certified Custodial Technician and Train the Trainer programs, as well as courses in Carpet Cleaning, Upholstery Cleaning, and more. Mark’s warm and simple approach has inspired many, and his deep respect of his students has set a good example for the industry. Mark has gone on to become an educational product developer for the cleaning industry and he graciously welcomes your ideas for new course development.
