As a result of the proven performance, we are now installing this system in other locations. Chris is someone you should turn to when you need an answer that is not easily found.”

He proposed an innovative solution that safeguarded our patients while simultaneously minimizing risks to our staff and the facility. Even if you have a well-thought-out plan in mind, I highly recommend consulting Chris. His fresh and cutting-edge insights will provide you with peace of mind, ensuring that you’re making the right decision.”

Aaron Kuehn, Former CEO at Ness County Hospital

“I first met Chris when he helped us design a large softener and brine system at a VA facility a few years ago. Initially, I was impressed by his extensive knowledge of water systems. However, I later discovered that his expertise stems from his third-generation lineage as a water system expert. Since then, I have consistently sought Chris’s professional advice and insights on water systems and Legionella control. I firmly believe that success lies in building a network of knowledgeable individuals, and Chris is one of those exceptional minds you should tap into for anything related to water, especially when it comes to Legionella. His expertise will lead you to success.”
