[4][5] Since the formation of the Apertura/Clausura, A.D. Isidro Metapán has been the dominant club in El Salvador football, winning ten championships.

Since the beginning of the 2000–01 season, A.D. Isidro Metapán has played its home games at the Estadio Jorge Calero Suárez.

In 2001, the newly born club won promotion to the Primera División with a 3–2 playoff win over Jocoro FC.

The club quickly consolidated their position as a mid-table side, and starting in Apertura 2004 began making title pushes.

In Apertura 2005, they finished the regular atop the table, defeated Once Municipal in the semi-finals, and only fell short of their first title after a 2–0 extra time loss to Vista Hermosa.

In Clausura 2007, the club finally bettered that result, taking home their first ever championship with a 1–0 extra time win over Luis Ángel Firpo.

Over the next several years, Isidro Metapán began to surpass the traditional powers of Salvadoran football (FAS, Firpo, Alianza, and Águila).

They won their second title in a penalty shootout over Chalatenango in Apertura 2008, then defended their crown in Clausura 2009 with a 1–0 win over Luis Ángel Firpo.

Meanwhile, domestically, Metapán won a sixth title in eight years with a 1–0 victory over Once Municipal the only goal coming from Paolo Suárez in the 51st minute.

For a moment it looked like the hero would be Metapán's top goal scorer Nicolás Muñoz, who scored from a free kick in extra time.

[9] On 25 May 2014 Isidro Metapán won the Primera División title for the ninth time in the club history, defeating Dragón on penalties 6–5.

Once again, Nicolás Muñoz played a very important role in taking the match to penalties with an extra time goal.
