Biff Poggi’s net worth is estimated at $10 million, an unusual figure for a football coach that reflects his parallel career as a successful hedge fund manager and business investor. Poggi founded the Samuel James Limited hedge fund in the 1990s, growing it from a $25,000 initial investment to an operation managing hundreds of millions of dollars, according to ESPN — a financial track record that makes him one of the wealthiest coaches in college football.
Updated March 2026: According to Wikipedia and Reuters, Biff Poggi served as Michigan’s interim head football coach from December 2025 following the firing of Sherrone Moore, coaching the team to a 3–1 record including a Citrus Bowl appearance before announcing he would not return as head coach for the 2026 season.
Francis Xavier “Biff” Poggi was born on June 6, 1960, in Baltimore, Maryland. He grew up in the Baltimore area and was an accomplished football player in his youth, earning recognition as a standout offensive lineman. He attended the University of Michigan, where he played offensive line for the Wolverines football team — building the deep connection to Michigan football that would later define key chapters of his coaching career. After graduating from Michigan, Poggi remained in the Baltimore area and pursued both business and coaching simultaneously, a dual-track career that eventually made him a uniquely wealthy figure in the college football coaching landscape. He is sometimes called the “multi-millionaire volunteer coach” for periods when he coached at the high school level while managing a successful hedge fund.
Poggi began his coaching career at the high school level in Baltimore, becoming head coach at the Gilman School, an elite private boys’ school. Over 13 years at Gilman, he won 13 conference titles and built the program into a regional powerhouse. He subsequently built St. Frances Academy’s football program into one of the top-ranked high school teams in the country, earning national recognition.
In 2021, Michigan head coach Jim Harbaugh recruited Poggi as an associate head coach, and Poggi joined the Wolverines staff — notably doing so for just $45,000 per year, a salary he could easily afford given his hedge fund wealth. Under Harbaugh’s tenure, Michigan won consecutive Big Ten championships and made the College Football Playoff, with Poggi contributing to an extraordinary run of program success. He left Michigan’s staff in 2022 and was hired as head coach at the University of North Carolina at Charlotte in 2023, going 6–16 over two seasons before leaving after the 2024 season.
Poggi’s most prominent moment in college football’s national spotlight came in December 2025, when Michigan fired head coach Sherrone Moore following a personal misconduct investigation. Michigan turned to Poggi as interim head coach to lead the team through the bowl season. He went 3–1 as interim coach, including a Citrus Bowl appearance against Texas, according to Wikipedia. He announced after the bowl season that he would not be returning as head coach for 2026, per Reuters.
Biff Poggi married Amelia Jean “Amy” Mix in 1986. The couple has five children together: three sons named Henry, Sam, and Jim, and two daughters named Mary and Mellie. The family is based in the Baltimore, Maryland area, where Poggi owns a grand estate in the suburbs, as reported by the New York Post. Poggi played football at the University of Michigan, giving him a personal connection to the program he would later coach. As of January 2026, he confirmed he would not return to coach Michigan’s program beyond his interim role, though his future plans in football have not been publicly disclosed.
Biff Poggi’s net worth is estimated at approximately $10 million, with some industry sources suggesting his hedge fund and business wealth may be higher, given his Samuel James Limited fund grew to manage hundreds of millions of dollars according to ESPN. His wealth derives primarily from his hedge fund and diversified business investments rather than his coaching salaries, which have ranged from $45,000 (Michigan associate HC) to $1 million per year (Charlotte HC).
Biff Poggi is married to Amelia Jean “Amy” Mix, whom he married in 1986. The couple has been together for nearly four decades and have five children: sons Henry, Sam, and Jim, and daughters Mary and Mellie. The family lives on a grand estate in the Baltimore, Maryland suburbs.
