Joffre "Dinamita" (which in Spanish means Dynamite) Guerron was born in a small Ecuadorian village called, Valle del Chota, where other important figures of Ecuadorian football have emerged, players such as Édison Méndez, Agustín Delgado, Ulises de la Cruz and Giovanny Espinoza.
He made his debut in the top Ecuadorian division with SD Aucas at the very young age of 16. He was then transferred to Argentine giants Boca Juniors where he played in the lower divisions of the team; however he never got a chance to debut with the senior team. In 2006 he returned to Ecuador, this time to Liga, at the request of the then manager, Juan Carlos Oblitas.
In 2007, Guerron began to hold a starting 11 position, with the new manager Edgardo Bauza. Guerron would finish the 2007 Serie A season as champion, bringing the club its 9th league title.
He impressed and dazzled many with his speed and talent as well as his pace in the 2008 Copa Libertadores with LDU Quito, scoring against Libertad of Paraguay with an individual play, and also against Estudiantes de La Plata, where Guerron took the ball individually past several defenders and shot the football very powerfully past the small space left on the goal-keeper's left side. Guerron in the semi-final versus Club America received a long pass from Jayro Campos on the right side of the field, dribbled past his defender to send the ball past Guillermo Ochoa and leave it for Luis Bolanos to just head the ball in, resulting in an important 1-1 away result.After drawing to America 0-0 at home, Liga reached the final where Guerrón played an important role in the victory over Fluminense, scoring a goal in the first leg, then putting in an energetic performance before scoring LDU's third goal in the 3-1 penalty shootout victory. He was member of the team that won Copa Libertadores in 2008, Liga Deportiva Universitaria de Quito. He was chosen by FIFA, through an election, as the best player of the 2008 Copa Libertadores.
It was confirmed on June 6, 2008 that Joffre would join Getafe CF for 4 years at a price of €4M Euros. Guerron made his league debut on August 31, 2008, starting against Sporting de Gijón. Guerron was taunted by fans of Sporting de Gijón on August 21, 2008, during his league debut match. Several parts of the stadium could be heard making monkey noises and other degrading taunts against the footballer. As a result, Swiss club teammate Fabio Celestini condemned the racist supporters in a later press conference calling them idiots and also praising Guerron's attitude throughout the match, although it was suggested that Joffre did not know the insults were directed at him. Gijón was fined a modest sum for the incident.
The club signed the Ecuadorian midfielder on loan from Getafe CF for one season, the Brazilians paid around 1 million Euros and can sign him on a permanent basis at the end of the season for 3 million. In his 2009 season debut, he played 15 league games, scoring 2 goalsin 2 victories against Santo Andre and Sport Recife. On February 4, in a 2010 Copa Libertadores match, he scored a beautiful goal with out virtually an angle to shoot from, winning 7-0 against Bolivian club Real Potosi. For the 2010 season, he only played 4 league matches, scoring only once against Guarani in a 2-2 draw.
In July 2010, Joffre joined the Brazilian club Atlético Paranaense for a transfer fee of €907,000 Euros. After playing for Paranaense for 2 seasons, he has become the teams icon and top goal-scorer. He has been shown interest by São Paulo FC, Flamengo, San Lorenzo, and more recently by Club América through the January and summer transfer windows of 2012.
