WBE Certification

Duffield Associates, Inc. has recently become a women-owned business. This ownership situation has provided us the unique opportunity to assist our clients in meeting subcontracting goals in markets that encourage supplier diversity.

Duffield Associates currently has the following certifications:
– WBE – State of Delaware, Office of Supplier Diversity
– WBE – City of Philadelphia, Office of Economic Opportunity

These certifications allow us to qualify as a WBE for many other clients, including the following:
– Exelon
– City of Dover
– University of Delaware
– And others that accept the certifications listed above.



Duffield is currently pursuing certification with the following entities:
– Washington Suburban Sanitary Commission (WSSC)
– City of Baltimore
– MDOT (WBE, not DBE)

Due to our success, Duffield Associates in combination with our affiliate companies exceeds the current annual revenue standards to be classified as a Small Business as defined by the Federal government. As such, we do not meet the requirements to become certified as a Federal Women Owned Small Business (WOSB) or as a Disadvantaged Business Enterprise (DBE) with the state DOT’s. However, the size standards change from time to time, and we may at some point become eligible for these programs.
