  • Kay Ah

    Some of the best customer service around. Everything runs so smoothly when dealing with Culligan. Great tasting water.

  • Rich Monsalvo

    Professional staff and knowledgeable. Staff takes the time to reach out to me and let me know when they’re going to drop off salt or service equipment. Great Culligan dealer, would recommend to friends.

  • Russell Miller

  • barbara reitz

    The staff are experienced and patient, helping me to understand the principals and value of using various components of their filtering system. The owner has been very responsive regarding delivery needs and also responded quickly and responsibly to some property damage done by a delivery truck . That speaks volumes!!

  • supercali fractalistic
