1. Early Life and Education
Mark Pellegrino was born on April 9, 1965, in Pasadena, California, and subsequently grew up in Van Nuys, California. He attended Notre Dame High School in Sherman Oaks. During his high school years, he co-founded and served as the singer for a heavy metal band named XL, which disbanded after he completed school.
Although Pellegrino enrolled in college and achieved a perfect academic record with straight A's, he decided to drop out after just one year. His path into acting was somewhat serendipitous; he saw an advertisement for a modeling agency called John Roberts Powers, where he received free training. It was during this training that a commercial agent, Bob Hoover, recognized his talent and arranged for him to connect with an agent and acting coaches. This marked his entry into the acting world, where he later discovered the Meisner acting method. At the time, he did not initially have a dream of becoming an actor.
For a significant part of his life, Mark Pellegrino believed his biological father was Bill Pellegrino, whom his mother divorced when Mark was two years old. As an adult, Mark conducted a search on ancestry.com to explore his heritage, which revealed that his DNA did not indicate Italian ancestry. Prior to the COVID-19 pandemic, he publicly sought assistance from fans of the TV show Supernatural on Twitter (now known as X) to help him find his real father. Within an hour of his post, his biological father, Gerry, was identified, along with the discovery that Mark has two sisters and three brothers. Gerry, his biological father, is of German descent.

3.1. Philosophical and Political Views
Pellegrino is an atheist. He is a devoted follower of Objectivism, a philosophical system developed by Russian-American writer Ayn Rand. Before embracing Objectivism, he identified as an environmentalist and was a registered member of the Democratic Party. He actively promotes Rand's ideas through two YouTube platforms: one is an affiliation with the Ayn Rand Centre UK, and the other is his personal account, where he hosts a series he created called Reality Checks, which features videos exploring philosophical topics related to everyday life.
He has described his political views as classical liberalism. While he acknowledged that libertarianism is the closest description of his political stance, he also views libertarianism as an anarchistic political ideology and has distanced himself from it, instead identifying as an Objectivist who recognizes the importance and place of government within society. He self-identifies as a "radical capitalist." These philosophical and political stances, while emphasizing individual liberty and economic freedom, have generated debate regarding their implications for social safety nets and collective welfare, and are viewed by some as aligning with conservative ideals concerning governmental scope.
Pellegrino is a co-founder of The American Capitalist Party. The party's core tenets include standing for reason, individual rights, limited constitutional government, and laissez-faire capitalism.
