At Merrimack, he was active in the Onstagers, Merrimack's student theater organization. He also played varsity baseball for the Warriors baseball team. During the summers of his college years, he was active in the training programs at the Williamstown Theatre Festival in Williamstown, Massachusetts. In 2014, he received an honorary doctorate in performing arts from Merrimack, where he also delivered that year's keynote address.
Besides playing Charlie Kelly on the hit FX television series It's Always Sunny in Philadelphia, he is also one of the show's executive producers and one of its writers, along with Rob McElhenney and Glenn Howerton. He has also appeared on several other television shows such as Third Watch, Law & Order, and Reno 911!.
