Municipal Grecia / Heredia

In 1998, the people from Grecia, led by former deputy Everardo Rodríguez, decided to give the people of the canton a new sports option. Feeling the need of having an own football club which competed in a non-amateur level. Having taken over the franchise of American FC, the club was founded on 16 August 1998. The club made its debut on 13 September 1998 by drawing 2–2 with Puriscal FC.

During its first decade, the team won the 2007 Apertura Championship in the Costa Rican Liga de Ascenso. On mid-2017 the club, managed by former Saprissa and Costa Rica captain Walter Centeno, defeated Jicaral to win the 2017 Clausura tournament, thus qualifying to a promotion play-off. Grecia would defeat Jicaral again to achieve the promotion to the Liga FPD for the first time.
