John and his crew are great! We had never owned a pool prior to our relocation to Las Vegas in 2013. We continued with John (Desert Oasis Pools) , who had serviced the prior owner's pool, based upon their strong recommendation. We have never been disappointed! John has been very patient with us over the last three years as we have learned the "in's-and--out's" of pool ownership. Our weekly cleaning is always perfect! Easy communications via text and email.
