Culligan Staff

Trust the Experts!

Culligan of the Rio Grande Valley is the Rio Grande Valley’s only complete water treatment source. We offer a wide range of products and services to treat your water needs for homes, offices and commercial/industrial applications. Our San Benito based business was established in 1975, and is a local, family-owned and operated business.

Winslow, Susan, and Tyler Stenseng, owners of Culligan of the Rio Grande Valley, have assembled a team of dedicated employees who strive to serve our customers with integrity and reliability. Our service teams’ combined years of experience is simply unmatched compared to any other water treatment company in the Rio Grande Valley. As members of the Water Quality Association (WQA), Texas Water Quality Association (TWQA), and as a part of a large international network of Culligan dealers, our employees are held to a higher standard of professionalism, giving you expert service from the people who know water.


We take great pride in the fact that water treatment is our only business, and we are also proud to say we have the most technologically advanced water treatment systems available. Culligan water treatment systems are proprietary, meaning only a licensed Culligan dealer can sell Culligan products. When it comes to water treatment, efficiency is very important, and only Culligan has our new HE (High Efficiency) water softener system and advanced drinking water systems. Another great thing about Culligan is that we like to be able to give you options. We sell equipment, provide a full service rental program, or provide financing. Our main objective is to find the best solution which offers you the best value for your needs for home or business. We know water, and when it comes to water treatment, we’re the experts. Please give us a call at (956) 399-1780 to inquire about our products and services.
