Hugo Pérez

In 1982, Pérez signed with the Los Angeles Aztecs of the NASL. He also spent time with the Tampa Bay Rowdies before ending up with the San Diego Sockers. In 1988, he was the championship MVP when the Sockers won the MISL championship. That summer he joined Ajax during the team's pre-season. Ajax manager Johan Cruyff expressed an interest in signing him, but the Sockers refused to release Pérez. In 1989, he played for the Los Angeles Heat of the Western Soccer Alliance. Cruyff then attempted to work a transfer for Pérez to Italian club Parma in 1990, but Parma needed Pérez to play in the World Cup in order to get him a work permit. Pérez was part of the 1990 World Cup Roster, but when U.S. coach Gansler left Pérez off the U.S. team that traveled, due to a question of match fitness due to injury, this nixed the move to Italy. Instead, Pérez moved to France where he played with Red Star Paris. From France, Pérez moved to Swedish First Division club Örgryte IS then Saudi Arabian First Division club Al-Ittihad. In 1994, he returned to the United States and played in the 1994 World Cup and after played for the Los Angeles Salsa of the American Professional Soccer League. Hugo played with the Salsa while negotiating a contract with C.D FAS. The Salsa folded at the end of the 1994 season and Pérez made his last move, to Primera División de Fútbol de El Salvador club C.D. FAS, commonly known as C.D. FAS. In both of Pérez' years with the club, 1994–1995 and 1995–1996, C.D. FAS won…

Pérez was a member of the American squad that competed at the 1983 FIFA World Youth Championship and 1984 Summer Olympics. He also helped the U.S. qualify for the 1988 Summer Olympics and the 1990 FIFA World Cup, which he missed when he tore ligaments in his leg playing for Red Star Paris, a French Second Division club. He was named U.S. Soccer Athlete of the Year in 1991. He played 73 international matches for the U.S. between 1984 and 1994, in which he scored thirteen goals. At the 1994 FIFA World Cup, Pérez played in the second-round game against Brazil.

In August 2002, he joined the University of San Francisco as an assistant coach to its men's soccer team. On December 7, 2007, the California Victory, a USL First Division expansion franchise, announced that Pérez had joined its staff as an assistant coach.

United States U-15

Pérez was coach of the U15s from August 7, 2012, to August 23, 2014. He resigned afterwards. He stated "Yes, this is my last camp, I don't know [what is next for me]; that is up to U.S. Soccer. Obviously, I'm employed by them and whatever they do I am open to it. It's been an honor to work with these kids and an honor to get to know them."

El Salvador

After Albert Roca resigned as coach of El Salvador in July 2015, Pérez once again expressed his interest in coaching El Salvador. On August 21, 2015, it was announced that Pérez has been hired as the new assistant coach of El Salvador to Jorge Rodríguez. In April 2021, after having coached the El Salvador under-23 national team, Pérez was named head coach of the senior team, the first American to coach El Salvador after 91 years. Under this tutelage, El Salvador began recruiting players born in the United States to Salvadoran parents, who later made up a quarter of their World Cup qualifying roster in 2021. On September 11, 2023, Pérez was fired as the head coach of the El Salvador national team the day following a 2–3 loss to Trinidad and Tobago during the 2023–24 CONCACAF Nations League.

Pérez was born in El Salvador, where both his grandfather and father both played professionally for C.D. FAS, the club with which Pérez would finish his career. He migrated with his family to the United States when he was 11 and gained his U.S. citizenship in the mid-1980s. He chose to forego college.
