Ranks No. 3211 on the 2007 Inc. 5,000 With Three-Year Sales Growth of 97.4%   NEW YORK, August 23, 2007 – Inc. today ranked Diagnostic Imaging Systems No. 3211 on its first-ever Inc. 5,000 list of the fastest-growing private companies in the country.  The Inc. 5,000, an extension of Inc. magazine’s annual Inc. 500 list, catches many businesses that are too big to grow at the pace required to make the Inc. 500, as well as a host of smaller firms. Taken as a whole, these companies represent the backbone of the U.S. economy.    “The Inc. 5,000 provides the most comprehensive look ever at the most important part of the economy – the entrepreneurial part,” said Inc. 5,000 Project Manager Jim Melloan.  “The expansion of the list has allowed us to tell the stories of larger companies, older companies, and  a wealth of companies in industries like Manufacturing and Construction that are underreported in the business media.   Diagnostic Imaging Systems has strong national and international relationships with both customers and vendors.  The owner, Joe Hecker, grew up in North Dakota.  He moved to the Black Hills of South Dakota in 1978.  Good Midwestern ethics are the base of this business he started in 1983, and DIS is honored to be placed as fourth in South Dakota on the Inc. 5000 list of fastest-growing businesses.  The employees of DIS share Joe’s enthusiasm for providing the best equipment and service for the best value.    Joe is the inventor of several accessory items for veterinary use known as the Versa-View family of products, and holds a patent on a dual laser guided x-ray field identification device.  He also designed our popular “orange” Ultra-portable x-ray unit.  DIS has the largest selection of veterinary radiology products and is one of the nations leading suppliers of digital radiology equipment.  Visit our website at www.vetxray.com for our online catalog.   Veterinarians rely on DIS for fast and friendly service.
