On his dad's side, his great-grandparents emigrated from Italy to secure a better future for their children and themselves.

His grandfather became the first elected Mayor of the City of Vineland and went on to become a Judge, despite not even speaking English until the 1st grade. Michael's father went on to start and build their family law firm.

On his mom's side, his grandparents were Polish Jews who met in a Nazi concentration camp during World War II and were, thank God, freed by Allied soldiers. After the war, they came to the United States, where his mom was born. They settled in Buena and his family ran a chicken farm.
