Barry D. Trebach, one of the Founding Partners of the Firm, was born in Brooklyn, New York in 1954.  He attended Vassar College (AB, 1976) and made Washington, DC his home after he graduated from the Antioch School of Law (JD, 1981). Immediately after graduation, Mr. Trebach became the judicial law clerk for the Honorable Frederick H. Weisberg of the District of Columbia Superior Court.  He is admitted to the District of Columbia (1981) and Maryland (1983) bars and is a member of the United States District Courts of the District of Columbia and Maryland.

Currently, Mr. Trebach is the lead defense counsel for an urban transit system in litigation involving claims for death and injury to several hundred customers and is panel counsel for the members of the Grocery Manufacturer Association.  Since 1981, he has represented doctors and hospitals in medical malpractice cases in Washington, DC and throughout the state of Maryland and has litigated and tried cases involving brain injuries, death, paralysis, birth injuries and more. Mr. Trebach has defended hotels, restaurants and national food producers in food borne illness cases and has worked with law enforcement (including the Federal Bureau of Investigation and United States Attorney’s Office), media relations firms, epidemiologists, and others to investigate and litigate injury and fraud cases across the country.

Mr. Trebach is a mediator and has served as an arbitrator since 1986 for the DC Superior Court, the DC Court of Appeals, the United States District Court for the District of Columbia and the Maryland Alternative Dispute Resolution Health Claims Board.

Mr. Trebach has lectured to lawyers, doctors, members of the food industry and insurance companies on defending food borne illness cases, defending medical malpractice cases and various litigation techniques. He has lectured at Rutgers University Medical School (formerly the University Medical and Dental School of New Jersey), the American Psychoanalytical Association, The Robert Wood Johnson Medical School, the Virginia Defense Lawyers Association, the Association for Professionals in Infection Control and Epidemiology, and the Grocery Manufacturer Association’s Annual Litigation Conference.
