2021 CETA Lifetime Achievement Award Recipient – Mr. Sam Humphrey

Mr. Sam Humphrey

Sam Humphrey has served as President of the Mi-T-M Corporation since 1998. Graduating from Eastern Illinois University he worked in both education and retail management where he developed a deep understanding of team building. Humphrey relies on his team building experiences today to lead the Mi-T-M management team in their continuous effort to improve business practices, manufacturing efficiencies and enhance customer relations. The scope of his leadership has spanned to virtually all aspects of Mi-T-M.


Humphrey has been instrumental in the growth of Mi-T-M since he joined the company in 1991 as Marketing Manager. AJ Spiegel, CEO and owner of Mi-T-M, came to rely on him for his strategic approach and sound decision making.


Mi-T-M had become well known for cold water pressure washers since the company was founded in 1971. In 1983 Mi-T-M decided it was time to make the leap to building hot water machines. Eventually Sam Humphrey earned a promotion to President of Mi-T-M and was a major force to drive the efforts of Mi-T-M to become a leader in this advanced segment of the cleaning equipment industry as well. Under Sam’s direction, the Mi-T-M company now manufacturers over 45 industrial models of pressure washers.


Always looking for solid growth opportunities Sam’s team realized the coming importance of water conservation and seeing the need to meet the federal, state and local clean water requirements, Humphrey led his team to develop a water reclamation division as a compliment to the industrial pressure washer product line. In 1998 the first Mi-T-M Biological Water Treatment System was installed at the Bay Hill Country Club in Orlando, Florida. In 2007 The Kiplinger Letter recognized the Mi-T-M Corporation as a leading manufacturer of water recycling technology.


Mi-T-M’s vision of growth through diversification was accomplished under the leadership of Sam Humphrey and his management team. Under his guidance, the Mi-T-M Corporation has progressed from a respectable cold water pressure washer manufacturer to currently manufacturing hot and cold pressure washers, air compressors, portable generators, wash water reclaim Systems, industrial wet/dry vacuums, jobsite boxes, portable heaters, water transfer pumps and a very sophisticated metal fabrication division as well as a world class industrial parts painting facility in a one million square foot facility in Peosta, Iowa.


Humphrey lends his knowledge and offers his support on many industry boards. He thrives on interacting with the customers and, over the years, cultivated lifelong friendships with many. As an avid hunter. When the opportunity permits, he has also shared his adventures with many friends, family and business associates.


With Humphrey’s full support, Mi-T-M will continue to play a big role in the Cleaning Equipment Trade Association. In his rare spare moments, Humphry supports local charities and most recently was a board member for the Peosta Community Center which was built and donated by Mi-T-M’s owner, AJ Spiegel.


While Sam Humphrey has truly spent a large portion of his adult life in shaping and serving in the Clean Equipment Industry, of all his professional accomplishments, Sam is most devoted to his family. With the support of his wife Candie and children Scott, Ashley and Kelly, the President of Mi-T-M will continue to embrace the challenges of today and lead the company into 2022 and beyond!

Mr. Jack Hill

“Having been a customer of General Pump for many years, I can vouch for Jack’s integrity, honesty, and work ethic. Jack truly is an asset to our industry.” Gary L. Scott – Alkota Cleaning Systems


Jack Hill has been in the pressure washer business for 37 years. He worked side by side with Mike Christopherson building General Pump into the great company it is today. Jack has spent his career developing and improving product for the cleaning equipment manufacturers and distributors in the industry. If you visit with Jack about a new product or about improving a current product, you never hear the word “No”. He will always go to work to solve the problem, or he will go to work having a product developed to help you.


Jack and General Pump have supported CETA since the beginning of the organization. You will always see General Pump on the trade show floor with Jack himself to greet you. For many years, Jack and General Pump have helped to sponsor the CETA Opening Reception that everyone looks forward to attending. It is the one place where all members come together to grab a bite to eat, perhaps share a drink and visit with friends.


Jack is a devoted husband to wife Kimberly and awesome father to his three sons, Jack, Jake, and John. Jack’s favorite pastime is spending as much time as possible at his cabin, his heaven on earth, on Lake Vermillion in northern Minnesota.


Jack is truly the voice of General Pump and is well known throughout the industry.
