Began working in the aquatics industry in 1980. I have designed over 2,000 public sector swimming pools and aquatic centers. As an CPO instructor and an AFO instructor I have taught over 2,000 students on the operation and maintenance of public swimming pools. I was a technical committee chairman of the Model Aquatic Health Code. I am a board member of the National Sanitation Foundation (NSF) Standard 50 for recreational water. I am on the commercial council for the Pool and Hot Tub Association. I have presented dozens of education sessions at the CPRS, NRPA and the World Aquatic Health Association. I have published dozens of articles for industry magazines.
