About Brett
Brett Callahan earned his law degree from George Mason University School of Law in 2007. He entered the profession after graduating at a time when the legal landscape was shifting. The classroom training at George Mason gave him exposure to both litigation and transactional subjects. That background shaped how he approached cases early in his career.
His résumé lists a series of federal and state admissions that mark a steady path through trial and appellate practice. He is a member of the Maryland State Bar. He also holds admission to the United States Court of Appeals for the Fourth Circuit and to multiple federal district and bankruptcy courts in Virginia and Maryland. Those admissions include the United States District Court for the Eastern District of Virginia, the United States District Court for the Western District of Virginia (certificate of good standing), the United States Bankruptcy Court for the Eastern District of Virginia, the United States Bankruptcy Court for the Western District of Virginia (certificate of good standing), and the United States District Court for the District of Maryland. The list signals frequent work in federal forum matters and bankruptcy proceedings.
Over the years Callahan has concentrated his practice on matters that require appearances in federal court and in bankruptcy settings. He represents clients in court filing, procedural hearings and contested matters that occur in those venues. He prepares briefs and motions for district courts and for the Fourth Circuit when appeals are involved. He also handles issues that arise during bankruptcy cases, including creditor claims and plan objections. His court admissions allow him to carry cases from district court through appellate review where necessary.
Callahan is on the roster of Vanderpool, Frostick & Nishanian, P.C. at its firm offices. At the firm he works on matters that cross both federal litigation and insolvency practice. Colleagues describe him as practical in the courtroom and methodical in written advocacy. He takes on tasks that range from discovery disputes to drafting appellate briefs and assisting clients through bankruptcy procedures.
His professional memberships reflect the dual nature of his practice: state bar registration alongside multiple federal and bankruptcy court admissions. That combination lets him move cases through local and federal systems. He continues to represent individuals and business clients in matters that require federal court appearances or involvement in bankruptcy court. His current practice concentrates on federal litigation and bankruptcy-related representation.
