Chip at Cornerstone ( website: cstonepools ) designed our pool and personally supervised every stage of construction. We LOVE our pool! If you live in the Phoenix Valley and plan to build a pool, you are missing out if you don't contact them. They design and build some amazing pools, and have relied almost entirely on word-of-mouth endorsements to build their company - they are THAT good. They have tons of references, too - a long list of satisfied customers. You won't find better service anywhere.
Pros: They go above and beyond, and make great pools
