Dale Ehrenheim HVACR Water Treatment Subject Matter Expert, Educator

Dale earned his college degree in biology and chemistry which helped pave his way into the water treatment field.  Over the course of his 30 plus years in water treatment, Dale has worked with the largest leading companies in the United States, and many others of all sizes.  He helped and trained hundreds in how to promote efficient operations, save water, and reduce overall maintenance costs, saving them thousands, even millions, of dollars.  His tenure includes employment and training from two of the largest water treatment companies in the world, now known as Suez Water Technologies and Nalco Water, an Ecolab company.  Each of these companies furthered and solidified his expertise within water treatment.  They helped him gain his credentials as a water treatment expert. 

Furthermore, they gave him the skills to be a leader in sales as well as customer service.

Rather than using a single know-it-all approach to solving problems, he chooses a consultative approach.  Dale does not believe in one size fits all solutions.  He helps his clients find their own best approach that fits their unique situation and needs.  Dale loves helping others and combining his technical expertise to solve problems and teach others.  He continues to do so today, primarily by focusing on teaching and coaching water treatment clients.

In his spare time, he loves to follow sports, cook, sing, and enjoy the outdoors among other things.
