Supplier Diversity

Roswell Park Comprehensive Cancer Center encourages opportunities for minority business enterprises (MBE), women-owned enterprises (WBE), service-disabled veteran-owned businesses (SDVOB), small businesses and other disadvantaged business programs.

The MWBE and SDVOB programs are critical to Roswell Park Comprehensive Cancer Center because it enables our procurement officers and staff the ability to select from a diversified pool of potential vendors thereby providing more options. It makes opportunities available to a broader audience who can in turn provide quality goods and services at a competitive price. It also helps facilitate efficient and timely acquisition of goods or services of the highest quality at the lowest practicable cost. In 2018, 43% of qualifying expenditures were awarded to MWBE.
