In 1967, Joe and Hildegarde Knaebel had a dream of owning their own business. It would be an uphill battle, with seven children, lots of bills, and very limited financial resources. Nonetheless, with the help of a few close friends, and a great banker, their business was started at the kitchen table of their home. From this humble beginning a very successful business was built.


As their children grew older and finished school, several joined the business. Three sons, a daughter, and a son-in-law have been extensively involved in the business since the 70’s.


Today there are seven members of the third generation involved in the business in various capacities from sales to administration.





Our combined warehouse space of 620,000 sq ft. plus over 400,000 sq ft. of outside storage houses over $26,000,000 in inventory provided by approximately 200 vendors. Our vendors are a very important part of our company providing high quality material and exceptional support.
