John J. Quinlan @ Showtime Series City On a Hill (2019) Posted on September 27, 2020 by Admin Friends have asked me what it was like being on the set of the Showtime series City On a Hill back in season 1. It was a great experience as a Massachusetts State Trooper. I have the greatest respect for the men in blue and to wear the full uniform was really something. Everyone on the set was really great. It gave me a chance to connect with some really amazing people like Darren McDonald who shared the incredible story of his son Ray with me. Those are the memories I’ll always have with me along the journey. John J. Quinlan
