Kreisers, Inc.

In 1905, Frederick Kreiser opened a pharmacy in Sioux Falls, South Dakota and Kreisers, Inc. was born. Remaining focused on med/surg supplies and equipment, Kreisers became a major regional distributor across the upper Midwest, offering a complete line of products to the care continuum.  


MMS - A Medical Supply Company

Founded in St. Louis in 1970, MMS expanded to become one of the largest, privately-owned, regional healthcare distributors in the United States. With a focus on the entire spectrum of healthcare, MMS leveraged their supply chain expertise to create customized service models across the continuum of care.
