The Project Management Day of Service (PMDOS®) in the Washington, D.C. region is PM4Change’s signature event and continues to be the primary means through which PM4Change achieves its mission of accelerating positive social outcomes through project management. This unique event connects nonprofit organizations with professional project managers who offer their expertise on a pro bono (free) basis to collaboratively tackle the nonprofits’ most pressing challenges. Through strategic planning and project scoping, the project managers enable nonprofits to optimize their operations and amplify their community impact. PMDOS exemplifies the power of service and collaboration, fostering meaningful partnerships that drive positive change.
