Good quality and efficient. My wife had been thinking about it for about 15 years. I chose them because they are nationwide and good reputation. I found Anthony and Sylvan through an online search. Our pool is geometric, no spa. It has a waterfall feature, and it is deep in the middle. We designed it to do swimming laps. I like the simple design. I love the travertine decking around it. Michael Turberville the project manager was excellent.
