Before establishing Lankler & Carragher with his old friend, classmate and colleague Andrew Lankler, Owen spent many years in both government service and private practice.

After graduating from the National Law Center, Owen served for seven years as an assistant district attorney in the Rackets Bureau, Organized Crime Narcotics Unit, Special Prosecutions Bureau and Trial Division of the New York County District Attorney's Office. As an assistant district attorney, Owen specialized in the investigation and prosecution of sophisticated financial crimes and both traditional and nontraditional organized crime groups. As a result of his successful efforts in several high profile investigations and trials, he was awarded numerous commendations from federal and state law enforcement agencies and was called upon to lecture on investigative techniques to industry and law enforcement organizations.

After leaving government service in 1995, Owen became a partner at a New York litigation firm before eventually founding Lankler & Carragher. Since entering private practice, Owen has successfully represented domestic and foreign insurers, telecommunications companies and other prominent businesses and individuals in matters throughout the United States. As a result of the depth and breadth of his experience, Owen continues to be called upon to lecture on insurance, telecommunications and risk management issues. He is AV rated by his peers.

Owen is admitted to practice in New York and Connecticut as well as the United States District Courts for the Southern and Eastern Districts of New York. He has been admitted pro hoc vice to several other federal and state courts throughout the United States. He is a member of the American Inns of Court, the New York County Lawyers Association and the American Bar Association.
