Now, 2026 has given us a brand new medical hit on TV that isn't set in Pittsburgh. Since "Best Medicine" debuted on Fox in January, 2026, it became a smash hit big enough to warrant a second season that will premiere this very year. Best's closest ally and bit of a rival is Sheriff Mark Mylow, a khaki-wearing, happy-go-lucky townie with a few secrets of his own. Mylow might look familiar to TV viewers, because he is played by Josh Segarra, who has been a staple of superhero TV for years. Segarra has had roles in the Disney+ "She-Hulk" series as well as the CW superhero staple "Arrow."
