Supplier Diversity

If you are seeking information on Certified Minority and Women Business Enterprises (MWBE) contractors, suppliers or consultants, refer to the links below. You will find a list of certified contractors as well as links to agencies from which we accept MWBE certification. These may be helpful in finding names, contact and other information for minority and women businesses able to provide products and services to fulfill your MWBE utilization goal on contract bids submitted to MSD.

Please see the following MWBE Directories. These directories provide a list of certified MBE and/or WBE firms accompanied by their certification information, contact information, and NAICS codes. (What’s a NAICS code?)
