Profile bio
About Mark Grannis
I help find creative solutions to a wide variety of legal problems for my clients. My caseload typically includes litigation matters (both trial and appellate) as well as regulatory advocacy. I also work as a mediator, mediating several cases per month through the D.C. Superior Court Multi-Door Dispute Resolution Program. I enjoy standing up to bullies, and am equally comfortable negotiating amicable resolutions among formerly bitter adversaries.My appellate experience includes arguing cases before the U.S. Supreme Court, several U.S. Courts of Appeals, and appellate courts in California, New York, and Maryland. Recently, I’ve focused my litigation work on financial services litigation, both prosecuting and defending claims for breach of fiduciary duty. I also have significant experience with privacy and reputation issues, as well as commercial disputes, constitutional litigation, election contests, product liability claims, antitrust issues, and probate matters.My two decades of experience within the field of telecommunications regulation encompasses representing clients before the FCC, the Departments of State and Commerce, and with foreign regulatory authorities and the ITU. I also advise clients on the rules and regulations governing the Federal Communications Commission, the Department of Energy, and the Federal Trade Commission.
Listed skills include Privacy Law, Appeals, Litigation, Dispute Resolution, and 15 others.
