Attention! Next Membership Meeting is May 18 at 7:00 pm on Zoom!
Welcome
You have reached the MAC-NVBUA association member website. We attempt to provide information and resources to assist our members in having a great member experience and umpiring.
Our umpires serve the greater Washington, DC, metropolitan area, including youth baseball, scholastic baseball, and adult recreation. Our assigning group also provides opportunities in college-level baseball.
To learn more about the life of our association, read our current or back issues of Blue Crew News, our membership online newsletter. If you have any questions about the association, please use our contact form to submit a question or comment.

BCN: 2025 Issue 5
Well, we’ve arrived at what I am sure is our collective favorite time of the year for those of us providing adjudication services on the local DC region high school baseball fields!
