Artosis was raised in Salem, New Hampshire. In his youth, his interests included skateboarding, basketball, chess tournaments, and competitive strategy games. Sports were his primary interest before he found competitive StarCraft. His consuming interest in playing and studying the game interfered with his high school education, where he failed many of his classes. He graduated from Salem High School in 2002.

He began a StarCraft tournament in New Hampshire, and was motivated to commentate on the matches by the dearth of English-speaking tournaments. Artosis has said that he felt like the game's community deserved more professional commentary, and decided to do it himself. His broadcasts were recorded to a computer and uploaded on the Web. Artosis was later approached by Korean broadcasting company International e-Sports Group (IEG) in 2008, and accepted their offer. He was the second Western StarCraft commentator, or caster, in South Korea, after Nick Plott.

Artosis is married and lives in South Korea with his wife and four children. His daughter, Aria, was born on January 14, 2012, twins Elise (daughter) and Malcolm (son) were born on April 28, 2017, and daughter Maeve was born on September 3, 2019

In Korea, Artosis shared a small apartment with 15 teenage pro gamers. As StarCraft II's launch neared, Artosis and another American commentator living in Seoul, Nick "Tasteless" Plott, had individually amassed significant followings, and had the interest of commercial broadcast networks. The two began casting together and became known by a portmanteau of their nicknames, Tasteless and Artosis, as Tastosis. Before this partnership, the two knew each other through their former competitive gaming careers, but became friends in Korea. Polygon attributed their success to their "magic" dynamic from complementary personalities, with Artosis encyclopedic and analytic, and Plott bold and sociable. In July 2013, Polygon reported Tastosis to be "the most well-known StarCraft 2 casting duo in the world", both broadcasting for GOMTV Global StarCraft II League. PC Gamer's Rich McCormick cited the pair in 2011 as examples of how the electronics sports profession is developing celebrities. The Verge's Paul Miller referred to Tastosis as "the primary practitioners of StarCraft casting". A crowdfunded documentary about their careers, Sons of StarCraft, was released in early 2013.

Artosis began playing the Blizzard Entertainment online collectible card game Hearthstone: Heroes of Warcraft during its closed beta in 2013, and began publishing Hearthstone podcasts in September 2013. In November 2013 Blizzard invited Artosis to participate in the Innkeeper's Invitational, a Hearthstone tournament hosted as part of the annual BlizzCon convention. On November 8, Artosis won the tournament and was crowned "Grandmaster of the Hearth".
