I have known Bill professionally since 1978, when he sold and serviced the water treatment contract here at the University of Tennessee, until 1990, when he moved to Nashville, TN. Through these 12 years, Bill provided water treatment consulting services to the University with honesty and technical expertise which has been unparalleled. Though the company he worked for changed names three times during that period, the service, dedication, and professionalism remained the only constant, servicing the University twice monthly, never missing a visit per my recollection. During this time, many projects were initiated to streamline operations, automate, improve control, conserve energy and decrease waste. Tremendous savings were able to be documented by the University as a result. System performances and equipment life increased. We still reap the benefits of the programs Bill began at the University. As Bill's counterpart at U.T., I had great satisfaction and am honored that I was able to be a part of implementing the water treatment program with Bill. A great lesson I learned was that regardless of company name changes, Bill was who the company was, and was so represented with excellence. I highly recommend Mr. Iverson as the principle at ATR. His education, honesty, and drive, together with his 20+ years of experience, in my opinion, qualify him as tops in the field of water treatment.
