Born and raised in Pennsylvania, Jonathan was an undergraduate at Penn State and continued his education at Harvard, spending several seasons with the Loeb Drama Center. He then spent five years in New York, appearing on and off Broadway in several regional theater productions.
Prior to his role as Riker, Jonathan had recurring roles in such shows as Falcon Crest, Paper Dolls and Bare Essence, and for years was a contract player on the daytime drama The Doctors. His other television work includes the television movie "The Nutcracker" and the critically praised roles in the miniseries "Dream West" and "North & South" (Parts I and II).
During the third season of Star Trek: The Next Generation, Jonathan made his directorial debut with an episode of the series entitled "The Offspring." He so impressed the executive producers with his efforts that he also directed two additional episodes in the fourth season, "Reunion" and "The Drumhead," and in the fifth season, "Cause and Effect." On the last Star Trek: The Next Generation movie, "Star Trek: First Contact", Jonathan had double duty -- as both director and co-star.
Jonathan is married to actress Genie Francis and resides in Los Angeles.
