John J. Hays, II


For John Hays, the practice of family law seemed to come naturally.


After graduating from Rutgers University in 2005, John chose to pursue a career as a lawyer at Boston University School of Law. While attending classes, John found the time to volunteer with Legal Services, which provides legal aid to Boston’s underserved community.

When law school was not in session during the summer, John worked for the Boston University Civil Litigation Clinic, providing a range of services to its clients. John was also one of the founders of the Boston University Chapter of Earthrights International, which is a nongovernmental, nonprofit organization that combines the power of law and the people in defense of human rights and the environment.


After obtaining his law degree from Boston University School of Law in 2008, John accepted a one-year Judicial Clerkship with now-retired New Jersey Superior Court Judge John J. Coyle, Jr., from whom he gained valuable experience in the best practice of New Jersey Family Law.

For the next three years, John further honed his skills by handling exclusively New Jersey family matters at a Somerset County law firm.

John joined DeTommaso Law Group, LLC in 2017. He shares the firm’s dedication to providing clients with the full range of legal options needed to enable them to conclude their divorce in the way that’s best for them and their families. Therefore, although John is an experienced family law litigator, he also has received special training in the Collaborative Practice approach to resolving New Jersey divorce cases.
