Veterinary Service

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 possibility to sell poultry related health products to a broader client base. Subsequently, John E. Pugliese, while working for Merck, saw the VSI potential and joined them in 1962.
