Theo Nathaniel Epstein (born December 29, 1973) is an American former Major League Baseball (MLB) executive who currently serves as a senior advisor and part-owner of Fenway Sports Group, which owns the Boston Red Sox of MLB and Liverpool F.C. of the English Premier League, among other properties.
Epstein helped to end two of the longest World Series droughts in MLB history. In 2004, when he was vice president and general manager for the Red Sox, the team won their first World Series championship in 86 years. His next job was president of baseball operations for the Chicago Cubs, who in 2016 won their first World Series championship in 108 years. After his tenure in Chicago, he joined MLB as a consultant.
Epstein was born to a secular Jewish family in New York City and raised in Brookline, Massachusetts. He graduated from Brookline High School in 1991, where he played baseball for the Brookline High School Warriors, but dreamed of working for the Red Sox.
Epstein attended Yale University, where he lived at Jonathan Edwards College. He served as sports editor of the Yale Daily News. He graduated in 1995 with a degree in American studies. During his time as an undergraduate, he wrote letters to several teams expressing interest in working for them. His letter to the Baltimore Orioles reached team executive Calvin Hill, a Yale alumnus and head of personnel, who invited him for an interview. Epstein interned for three consecutive summers for the Orioles. Eventually he was hired as the public relations assistant for the Orioles.
Epstein then moved with Larry Lucchino to the San Diego Padres as director of player development. While working for the Padres, he also studied at the University of San Diego School of Law and earned a Juris Doctor degree at Lucchino's suggestion. Epstein based his class selection on which professors seemed to be the most lenient with attendance policies given the Padres' often-late work hours. By studying law, Epstein was invited to take part in high-level negotiations and discussions by then-GM Kevin Towers since few in the Padres' small operations division had a legal background to understand contract language. He worked his way up to become the team's director of baseball operations.
After leaving the position as the Padres' President, Lucchino became president and chief executive officer (CEO) of the Red Sox on February 27, 2002 and hired Epstein to work under him. At the end of the 2002 season, Lucchino appointed Epstein to replace interim general manager (GM) Mike Port. Epstein is credited with trading away Nomar Garciaparra and acquiring Bill Mueller and Curt Schilling, moves that helped break the "Curse of the Bambino" when the Red Sox defeated the St. Louis Cardinals in the 2004 World Series, their first championship since 1918.
On October 31, 2005, he resigned, rejecting a three-year, $1.5-million-per-year contract for personal reasons. According to The Boston Globe, "This is a job you have to give your whole heart and soul to", he said. "In the end, after a long period of reflection about myself and the program, I decided I could no longer put my whole heart and soul into it." As it was Halloween the night he resigned from the Red Sox, he left Fenway Park wearing a gorilla suit in an attempt to avoid reporters. A witness reported spotting a person wearing a gorilla suit driving a Volvo similar to Epstein's that night. The suit was loaned to him and was later auctioned for $11,000. The money raised was given to The Jimmy Fund and the Foundation to be Named Later (FTBNL).
Epstein remained in contact with the team's front office and in January 2006, he and Red Sox management announced he would return, resuming the role of general manager and adding the title of executive vice president. The Red Sox went on to win the 2007 World Series, Epstein's second championship with Boston. In November 2007, Epstein announced, at the annual general manager meeting, that he had signed a new contract with the Red Sox but declined to disclose the terms of the deal.
On October 12, 2011, Epstein agreed to a five-year contract worth $18.5 million with the Chicago Cubs. On October 19, 2011, it was reported that Epstein's official title with the Cubs would be president and that San Diego Padres general manager Jed Hoyer would take the GM position with the Cubs.
On October 23, 2011, he took out a full-page ad in The Boston Globe, thanking Red Sox fans and the team's owners for their support. Two days later, the Cubs officially introduced Epstein as
president of baseball operations. The Cubs finished in last place in the National League Central for the first three years of Epstein's presidency, as the focus was to acquire young talent rather than maximize short-term competitiveness. After a three-year rebuild, the Cubs clinched a playoff berth in 2015 and advanced to the National League Championship Series, where they were swept by the New York Mets.
Epstein signed an extension with the club on September 28, 2016, with a contract estimated to be worth up to $25 million. The Cubs would proceed to break the so-called "Curse of the Billy Goat" by defeating Cleveland Indians in the 2016 World Series, their first championship since 1908.
Epstein stepped down from his role on the Cubs on November 20, 2020. Jed Hoyer, Epstein's long-time deputy, took over his position.
MLB consultant and private equity
In January 2021, MLB hired Epstein as a consultant for "on-field matters". Later that year, he joined private equity firm Arctos Partners.
On February 2, 2024, Fenway Sports Group announced that Epstein would return to the company as a senior adviser, while also joining its ownership group pending MLB approval.
Epstein has a twin brother, Paul, who is a social worker at Brookline High School in Brookline, Massachusetts. He and Paul are co-founders of "The Foundation to be Named Later", established in 2005.
Epstein's grandfather, Philip G. Epstein, and great-uncle, Julius J. Epstein – with Howard E. Koch – won Academy Awards for the screenplay of Casablanca, while his father, novelist Leslie Epstein, headed the Creative Writing Program at Boston University. His mother, Ilene (Gradman), opened a clothing store. Epstein's sister, Anya, is a screenwriter and television producer (Homicide: Life on the Street and Tell Me You Love Me).
