Background and career
Mark Justin Dantonio (born March 9, 1956) is an American former college football coach and player. He was the head coach at Michigan State University from 2007 to 2019. He led the Michigan State Spartans to three Big Ten Conference championships, and eight victories over archrival Michigan in 13 years. In 2013, he coached Michigan State to its first 13-win season and the program's fifth trip to the Rose Bowl, where they defeated Stanford and finished the season ranked No. 3 in the nation. This was the second time a Big Ten team reached the 13-win mark, the previous being Ohio State's national championship season in 2002, where Dantonio was the defensive coordinator. The 2013 season also marked the first time a Big Ten team won nine conference games each by double digits. In 2015, Dantonio became the first head coach in Big Ten history to achieve at least 11 wins in five of six seasons. On December 6, 2015, Dantonio's Spartans qualified for the College Football Playoff for the first time in the program's history. In 2006, Dantonio was hired as the Spartans' head coach, returning to the school where he served six years as an assistant coach under Nick Saban and Bobby Williams. Known as a defensive-minded coach, Dantonio led the Spartans to the school's first bowl game win since 2001, in the 2012 Outback Bowl, and the school's first Rose Bowl since 1988 in 2014. Dantonio's Spartans hold the active school record with four consecutive bowl wins. On October 8, 2011, Dantonio signed a contract extension that made him a "Spartan for life." In 2014, he earned the second highest salary among college football coaches, due largely to a retention bonus. On September 21, 2019, with his 110th victory, Dantonio became the winningest head coach in MSU football surpassing Duffy Daugherty. Dantonio had compiled a 110–52 record through this date at Michigan State, giving him a .691 winning percentage, the highest of any Michigan State football coach since Biggie Munn, who coached the Spartans from 1947 to 1953. Dantonio retired as the head coach of the Michigan State football team in February 2020 after 13 seasons and 114 wins. He briefly rejoined the team in 2023 as an associate head coach in the wake of Mel Tucker's suspension and the elevation of Harlon Barnett to interim head coach.
Mark Dantonio was born in El Paso, Texas, to Justin Dantonio and Maryan (née Sonsalla) Dantonio. He is of Italian descent (father) and Polish descent (mother). Dantonio's grandfather Frank D'antonio moved from Montenerodomo, Italy, to the United States – losing the apostrophe at Ellis Island – in 1912. Dantonio's father played basketball at Salem University and met his mother while teaching in El Paso. Mark was the second of four boys. When Mark was one, the family moved to Zanesville, Ohio, where Justin became the vice principal and basketball coach at Zanesville High School. Dantonio was an all-state safety at Zanesville.
Dantonio attended the University of South Carolina and earned three letters as a defensive back for coach Jim Carlen for the Gamecocks from 1976–78. He earned a bachelor's degree in education from South Carolina in 1979. Dantonio later earned a master's degree in education from Ohio University in 1980.
Dantonio began his coaching career at Ohio University, where he was a graduate assistant. In 1981, he made his first stop in the Big Ten Conference when he moved on to Purdue University as a graduate assistant. He spent two years, in 1983 and 1984, as a graduate assistant at Ohio State University under head coach Earle Bruce. In 1986, he began a five-year stint on Jim Tressel's staff at Youngstown State University as a defensive secondary coach. In 1990, Dantonio led the Penguins' defense to an 11–0 record and a No. 2 ranking nationally. Glen Mason hired Dantonio in 1991 to be the defensive secondary coach for the Kansas Jayhawks. When Nick Saban was hired at Michigan State in 1995, he hired Dantonio to join his staff in East Lansing where he remained even after Saban left for LSU. After Bobby Williams was named head coach in 1999 following Saban's departure, Dantonio was promoted to associate head coach where he remained through the 2000 season. At Ohio State in 2001, Dantonio reunited with his former Youngstown State boss and good friend Jim Tressel when he opted out of East Lansing to serve as defensive coordinator at Ohio State University for three seasons. His defense became known as one of the stingiest in the country. During the Buckeyes' 2002 National Championship season, Ohio State ranked second nationally in scoring defense and third in rushing defense. For his efforts, Dantonio was named a 2002 finalist for the Broyles Award, given annually to the nation's top college football assistant coach. In the 2003 season, his defense ranked number one in the country in rushing defense and ninth in total defense, which led the Buckeyes to an 11–2 record and No. 4 national ranking. Six Buckeye defenders were named first team All-Big Ten during Dantonio's tenure. Thirteen were drafted into the NFL, including two first round picks in Chris Gamble and Will Smith.
Dantonio was named head coach at Cincinnati on December 23, 2003. He became the first head coach in 23 years to lead the school to a winning season in his first season at UC. The Bearcats' 7–5 record included a 5–3 record in Conference USA, which was good enough for a second-place finish. The Bearcats finished the season on a winning note with a 32–14 win over Marshall in the Fort Worth Bowl. During Dantonio's time at UC, he led the Bearcats to a bowl game victory and directed the team's transition into the Big East Conference. As head coach, Dantonio had 15 players earn all-conference honors and 25 received conference academic recognition.
Mark Dantonio became the 24th head coach at Michigan State on November 27, 2006. Upon his arrival, Dantonio planned to return the Spartans to a more traditional philosophy on offense and defense, eliminating the spread offense and the "bandit" linebacker/safety position used under previous head coach John L. Smith.
