Dillon understands the entrepreneurial spirit and the risk that comes with running a business. He and his wife started their own business selling a product they invented. He knows the concerns of business owners, the requirements of starting a business and the cost-consciousness that comes with the endeavor.

As a member of the firm’s Business Litigation Service Group, Dillon represents clients at every level of litigation over contract and warranty disputes, construction disagreements, employment issues, property claims, bankruptcy disputes, municipal issues, and any other issue that requires advice of counsel in advance of or in conjunction with litigation. He works with foreign and domestic corporations, construction companies, municipalities, homeowners’ associations, homeowners, and banks to prosecute their claims against other entities, defend against similar claims from other entities, and, perhaps most importantly, work with opposing parties to resolve disputes outside of litigation. He seeks to resolve cases quickly and economically, but has the skill-set to take cases all the way to trial through appeal.

Dillon provides legal counsel to his clients in administrative matters, arbitrations, mediations, courtroom litigation, and appeals. His extensive legal experience on each side of the courtroom, in both state and federal courts, as both a criminal and civil attorney, and at every conceivable legal stage, provide him with insight into the gestalt that is litigation, and how that litigation can be handled most effectively and efficiently.

Dillon recently returned from active duty as a recalled Reservist in the U.S. Navy Reserve JAG Corps serving as the Assistant Staff Judge Advocate of the Reserve Component Command Great Lakes. Prior to joining private practice, Dillon served for eight years as a Navy JAG Corps Officer, where he both prosecuted and defended sailors, marines, and coastguardsmen in Courts-Martial, Administrative Separation Boards, and in various other administrative tribunals. He also served as appellate defense counsel for more than 100 convicted sailors and marines in appeals before the Navy and Marine Corps Court of Criminal Appeals, the Court of Appeals for the Armed Forces, and the United States Supreme Court.
