They even went above and beyond on an additional request at the appointment. I wholeheartedly recommend “The Water Doctor” to anyone in need of water softener and filtration system solutions, or plumbing needs. Trust me, you won’t be disappointed! Thank you, “The Water Doctor,” for providing such an exceptional service and enhancing the quality of life in my home.

    The best customer service I have ever experienced from start to finish. Installation was fast and very efficient. They took their time explaining everything making sure we understood how to maintain system and how it worked
    Very easy to talk to. Other companies that came to give estimates seemes like they were just going through the motions. The Water Doctor was like we were talking to friends. Do yourself a favor, choose The Water Doctor.

    Patricia was very helpful and was able to guide me through an issue I was having with an old system. She answered all my questions and pointed me in the right direction, from across the country!

    one of the most professional service companies i have worked with . Hugo installed a water softener in our first home and transferred it to our forever home . No issues with our systems and scheduled services were done in a timely manner …

    Hugo and Patricia own and operate the Water Doctor, and we are thankful for their business. We met them a few years ago after moving into what was a relatively new subdivision at the time. Patricia and Hugo came by and explained how the water softener and reverse osmosis system worked. They discussed the advantages and conducted water tests to demonstrate the difference between regular tap water and softener/reverse osmosis water.
    There were no sales gimmicks or fast talk, just facts, and we appreciated their honesty and integrity. We will continue to work with Hugo and Patricia as long as we have our water softener system. We highly recommend doing business with “The Water Doctor”. You get more than your money’s worth.

    We have a system in our home and at the office. They do great quality work, and are extremely reliable with appointments. We are very pleased with their customer service, professional conduct, and the overall product.

    The tech who came to my home – Hugo – informed me that the water softening system I have is new enough that the warrantee is still in effect. He even called someone from that company to verify it for me. He could have easily serviced the system, charged me, and not said a word about it, but he didn’t. He did the right thing. This is a company with high standards that, sadly, all too many companies do not have. I would absolutely call The Water Doctor again for plumbing issues. It was so refreshing to talk with them and have them be more interested in being a trustworthy company and doing the right thing, rather than just making a buck.

    We had a busted pipe in our garage from the snowpocalypse. Saw them servicing our neighbors’ pipes across the street. We waved (frantically lol) them over and a few minutes later, our pipe was repaired. They did not ask for payment except a donation to the Battered Women’s Shelter under their name. The Lozanos were consummate professionals and very pleasant to work with. God bless their kindness.



    Jeff A.


    AMAZING! Hugo was a pleasure to work with. He was on time, finished the install in less than two hours, left no trace behind and did an excellent job explaining everything. I would highly recommend The Water Doctor!



    Josh G.


    We are over the moon with the service that Water Doctor provided. The install was very quick and they explained everything to us very thoroughly. Couldnâ t be happier and would gladly recommend their services to anyone looking for a water softener.
