McNiven Ranch Supply Ltd.(MRSL) is a family business located in Southern Alberta, two hours east of Calgary on the McNiven Ranch. Kathy McNiven purchased Muck Boots in the US for use on the ranch. Muck Boots proved to be warm, comfortable and incredibly functional for ranch life. McNiven Ranch Supply Ltd. was created in 2006 and began to import them for sale. During an extensive testing period of the footwear at a grassroots level, the demand for
Muck Boots grew at a furious rate. MRSL expanded in the fall of 2007. At that time, Laurie Fuller (Kathy's sister) joined MRSL bringing her organization and IT skills to the company.

Since the fall of 2007, the number of retailers has increased on a daily basis. The company built a 10,000 square foot warehouse on the ranch following a growing trend in western Canada to move warehousing out of urban centres. From modest beginnings, MRSL has now expanded to encompass 4 full time employees, 6 part time, a Sales Rep. Agency and a Board of Directors.

The retail stores sell Muck Boots for the same reason we do - they wear them and believe in them.

President & Vice President

Kathy, her husband Mike along with their three sons and two daughter-in-law's run a commercial herd of black Maine-Anjou X Angus cows and do their ranch work the traditional way - with horses. Laurie lives in the nearby town of Duchess with her family and commutes to the ranch for work. Kathy and Laurie both have an extensive history with horses: hunter/jumpers, thoroughbred and quarter race horses. Now it is roping and ranch horses. Both are animal people, who between them have sixteen horses, four dogs, nine cats and a sheep named Mrs. Woolworth who just showed up at the ranch one day. We own a third generation family cabin near Wainwright where we and our children continually put our Muck Boots to the "waterproof" test.
