Compassionate & Hard-Working Hingham Attorney & Mediator
David’s strengths in family law draw on his broad legal background. Before forming Kellem✶Mahoney Family Law & Mediation Group, P.C., he spent 25 years representing clients in the wide range of areas that relate to family law including divorce, real estate, business representation, litigation, and wills and estates.
David’s training in criminal law informs his representation of clients in restraining order and abuse cases. From 1983 to 1987, he prosecuted street-crime cases in Manhattan as an assistant district attorney with the New York County District Attorney’s Office. His work included jury trials, grand jury presentations, and appeals involving cases of murder, robbery, narcotics sales, burglary, weapons possession and sexual assault.
After earning a bachelor’s degree from Georgetown University, David graduated with honors from Suffolk University Law School in 1981. He honed his writing skills as lead articles editor of the Suffolk University Law Review and after graduation as a law clerk to the Honorable Joseph R. Weisberger of the Rhode Island Supreme Court.
David also has a special interest in family mediation and is dedicated to its growth and development. To secure his representation, contact the Hingham divorce attorney at (781) 304-4001.
