Vermont home

When he wasn’t filming, the actor lived with his family in Vermont. In a 2020 interview with Southern Living magazine, the actor talked about how his home life resembled the lives of the characters he played for Hallmark. For example, he and his children would cut down their own Christmas tree every year.

“We go to a little, wonderful, vegetable market stand,” he said. “And then my son and I, we put it up. All the decorations come out into the living room, a bottle of wine gets set down on the table and we always put on the exact same album. It’s Frank Sinatra’s Jolly Christmas.”
