Company
VSI was incorporated on February 6, 1960. This was the result of a relationship which existed between Willis D. Woodward, DVM, and Donald W. Rosenberg, DVM, in a joint practice, and with Frank G. Sweetman, a former sales representative for Van Waters and Rogers.
They formed VSI in order to take advantage of the opportunity to sell poultry related health products to a broader customer base. Subsequently, John E. Pugliese, while working for Merck, saw the VSI potential and joined them in 1962.
Over the years, VSI management saw various opportunities to expand into many diverse areas. Today, the company that started as primarily a poultry distributor now offers a broad line of products to over 3000 customers. These include those in the beef, dairy, and poultry business, as well as feed supply and pet stores.
