The 40-year-old is the Costa Rican side's third manager in six months. He replaces Claudio Jara, who took the reigns in August following the resignation of Jacques Odir.
Jara, played 46 times for Costa Rica from 1983 to 1994 after making his professional debut for Herediano in 1982. Last month, he guided Herediano to the finals of the Costa Rican Torneo Invierno, where the club fell to Alajuelense 3-2 on aggregate.
Solis, who won 110 caps for Costa Rica, enjoyed a lengthy career that began in 1990 with Herediano. After stops with clubs such as Derby County (England), San Jose Earthquakes (USA), OFI Crete (Greece), Irapuato (Mexico) and Comunicaciones (Guatemala), he retired in 2010 as a member of his original team.
The new coaching staff, which is comprised by Briance Camacho (assistant), Vinicio Montero (assistant), Milton Rivas (trainer) and Oscar Mora (goalkeeping coach), will begin its work on Wednesday, January 9.
Herediano's first game in the 2013 Torneo Verano is scheduled for January 13 against Santos de Guápiles. It will also meet the LA Galaxy in the Champions League quarterfinals on March 7 and 13.
