After receiving his Bachelors of Science degree in Chemistry from the State University of New York at Binghamton, he worked at Fritzsche, Dodge & Olcott (FD&O), which was the oldest manufacturer of flavors and fragrances in the country, and a subsidiary of BASF Corporation.

He was then promoted to Manager of their Basic Products Division, and then onto Account Manager for their Flavors and Fragrances Division. In 1986, Dave changed groups within BASF as he was promoted to field sales for the BASF Fine Chemicals group, representing both their lines of Nutritional Ingredients and of the Knoll Fine Chemicals bulk Active Pharmaceutical Ingredients (API’s).

His years of experience as a Chemist and a Salesman made this a natural progression offering deep-rooted experience in the products offered by Pharm-Rx. His dedication to the growth of both its customers and suppliers earned Pharm-Rx and Dave an exceptional degree of loyalty, and an outstanding reputation in the industry.
