You can tell Roger Olson really likes building pools. He knew the depth and size(small) of my exercise pool was very important to me. He was on the job, even though it was 30 miles from Midlothian, everytime something important was done. The pool turned out perfect. The only problem was his choice of controls: Pentair Troy Barron gave poor service, and now I suspect he sold Roger a much more complex system than i needed(there is no light, no spa). He gave a very hurried instruction, answered a few phone calls, and then stopped answering my calls. I eventually called the Pentair customer service number, who sent out a factory certified installer(Tony Roper, Advanced Pool Care, Weatherford, TX). He rewired parts of the panel, moved the remote antenna, and replaced the defective remote controller. It has worked great for 6 months now.
