Quinto was born on June 2, 1977, in Pittsburgh, Pennsylvania to Margaret J. "Margo" (née McArdle) and Joseph John "Joe" Quinto, an investment banker and a barber, who was of Italian descent. Quinto's father died of cancer when he was seven. Thus, Quinto and his brother were raised solely by their mother. He grew up Catholic and in the suburb of Green Tree, Pennsylvania, where he attended Saints Simon and Jude Catholic School, which closed in 2010. Quinto graduated from Central Catholic High School in 1995, where he won the Gene Kelly Award for Best Supporting Actor in his school's musical. He later attended Carnegie Mellon University's School of Drama, where he graduated from in 1999.
Quinto's first major role came in 2003 on FOX's television series 24. He appeared in a recurring role as Adam Kaufman. However, Quinto is arguably best known for his roles as Sylar on NBC's science fiction television drama series Heroes. He remained in this role from 2006-2010, and Spock in the Star Trek franchise.
In October 2011, Quinto publicly came out as gay. After the suicide of gay teenager Jamey Rodemeyer, he realized "that living a gay life without publicly acknowledging it is simply not enough to make any significant contribution to the immense work that lies ahead on the road to complete equality." Forgoing his coming out, Quinto had long since been an active supporter of gay rights, contributing to such organizations as the It Gets Better Project and Trevor Project.
