They began their marriage in Parsippany before settling in Denville to raise their family. She was a full-time mother, a wife, and teacher. Theresa was a devoted teacher at Randolph High School, teaching 11th and 12th grade Mathematics, for 33 years before retiring. She was a member of the New Jersey Education Association (NJEA). Above anything else, Theresa knew that life was about family, the memories that we make, the things we learn and the people that we meet.
