In the world of 90s sitcoms, the character Mark Healy emerged as a symbol of rebellion: a leather jacket, a powerful motorcycle, and a carefree appearance. But behind that facade, through Glenn Quinn ‘s masterful portrayal , audiences discovered a Mark who was affectionate, loyal, and an indispensable part of the Conner family.
Glenn Quinn’s sudden passing on December 3, 2002, left a huge void in the hearts of his colleagues and fans.

Born in Dublin, Glenn Quinn brought his expressive voice and charming, romantic demeanor to Hollywood. Before becoming famous for his role in Roseanne , he had already demonstrated his versatile acting abilities.
