Helen met her husband Doug while he was coaching offensive line at Northeastern University. Marrone, who at that time was at a local pub with his colleagues, wrote on a paper napkin what he was looking for in a girlfriend. A girl named Colleen Corran got the napkin and told him that he should meet her roommate at Boston College. Shortly after, they had their first date and the rest is history.
After dating for six years, Helen and Doug tied the knot in 1999. The couple has three lovely children together.
