I cannot put into words how impressed my husband and I have been with the Great Lakes Water Treatment company, especially the superior customer service we have received from their sales representative Garrett (Gary) Gabel! He not only blew us away with his incredibly impressive demonstration, but truly went above and beyond the call of duty to answer all of our questions and concerns prior to the installation of our water treatment and reverse osmosis systems. He still is in touch regularly, and we couldn’t be happier with our system!
