Mark Coffey, owner of Sioux City Culligan is the third generation of his family to operate the Culligan franchise in the Sioux City area. The business being established in 1939 and is one of the earliest franchises in Culligan history.
Culligan founder Emmett J. Culligan was born in 1893 in Yankton, South Dakota. His family moved to Sioux City before the turn of the century. Emmett was an entrepreneur who introduced the world to soft water in 1921. Emmett Culligan began franchising his soft water business in 1936 in Northbrook, Illinois.
In 1938 John Coffey, Mark’s grandfather, was offered a position with the newly established water conditioning Culligan franchise in Sioux Falls, South Dakota, originally called Sioux City Soft Water Service, Inc. Emmett Culligan was very impressed with John Coffey’s talent in the water industry and offered him the franchise in the Sioux City area in 1939. Mildred Coffey, John’s wife, assumed position of CEO when John passed away in 1945. Mildred Coffey operated the business from 1945 until her death in 1960. During this time she built the franchise’s current building at 1111 West 21st Street in Sioux City, Iowa. Sons Jerry and John and daughter Katherine became the second generation of Culligan owners. Through the years the water conditioning business continued to grow with the introduction of automatic softeners, drinking water systems and salt and bottled water delivery programs. Culligan became not only a household name, but a leading force in commercial water treatment systems.]
One of 8 grandchildren Mark Coffey attended the University of Iowa. After graduation Mark returned to Sioux City to assist in the family water business. Mark has since purchased the business from family members and is the third generation of the Coffey family to own and operate this Culligan franchise.

Do what they say. Dependable service.

I recently updated my service and wish to thank Dave and Tony for excellent friendly service. Also appreciate the friendly young lady on phone, sorry I don’t have her name.

Went above and beyond to make sure I got the right part. Also fixed another problem.

I get my salt/ bottle water delivered. The delivery guy is always helpful and ask if there is anything else I needed. Always have received great customer service with the staff at culligan of Sioux City.

We have worked with Culligan for 5 plus years and used a variety of their services. Each service we have been very happy with! We first used them for their water cooler service, we loved that we could have filtered water so inexpensive since we did not have that option in our fridge. When we moved we wanted to install a water softener, the whole experience was great from calling the office to get information and set up our appointment to the installation. Our install was on time, professional and knowledgeable to very friendly! We have set up a drop off with Culligan for our salt, this is a great feature for us because I don’t have to get the salt on top of groceries and kids. I have the option to have them drop it at my door or carry it in and fill my softener for me. We are looking into a water filter system in our sink and again the whole process was a great one from getting information, setting up the appointment and having someone come out. The best part was he looked at and told us every option we had and not once did I feel pushed to buy!! Never once have we been disappointed with our services from Culligan! We will be a Culligan lifer!!
