About William J.
William J. Walsh earned a B.S. from Tulane University before returning to law school at George Mason University School of Law, where he received his J.D. He came to law through a mix of classroom study and practical training. Those years shaped his approach to legal problems: precise research, careful writing and an eye for procedural detail.
After law school he entered private practice and became an associate at McCandlish & Lillard, P.C. In that role he has handled research, prepared pleadings and supported trial teams. He has worked on filings in multiple forums and taken on client-facing responsibilities as matters developed. Colleagues describe his work as methodical and focused on clear legal writing.
Walsh is licensed to practice in the District of Columbia and in Virginia. That dual admission lets him take cases that cross local and regional lines. He has experience drafting motions, preparing discovery and assisting at hearings. He also advises clients on compliance steps and procedural strategy when cases involve overlapping jurisdictions.
His practice has involved both court appearances and administrative matters, reflecting the mixed docket typical of regional firms. He spends time preparing written advocacy and counseling clients on next steps after rulings or regulatory actions. He has managed calendaring for complex matters and coordinated with experts where technical issues arose.
Colleagues say he approaches each file by breaking problems into manageable tasks, then communicating options plainly to clients. He blends attention to procedural detail with steady courtroom preparation. His current practice focuses on representing clients in matters arising under the laws of the District of Columbia and Virginia.
