In time, the group became larger by catering to local Dominicans and other nationalities. In 2001 they were invited to participate in a veteran tournament organized by the Dominican Football Federation, ultimately becoming the champions. The club went on to participate in the Third Dominican Division.[3]
Months later, the club became champion in its first participation in an official competition. This championship allowed them to ascend to the Second Division, which involved a greater challenge.
The newly promoted Club Atlético Pantoja again became champion of the Second Division league, a team made up mostly of veterans. This team had achieved the feat of "champion" three consecutive times, allowing them promotion to the maximum category of soccer in the Dominican Republic, Primera División de Republica Dominicana. This group would propose to reach another milestone, the title of First Division. From then a technical body was hired, in addition to adding young players as reinforcements. The fusion of youth and experience led the Club to reach the maximum laureate in Dominican football: the Primera División championship.
The club in a short time positioned itself as one of the winningest clubs from the Dominican Republic. The club has taken place in the CONCACAF Champions Cup (Formerly CONCACAF Champions League) a total of two times as of the 2024 season.[4] Atlético Pantoja became the first association football club from the Dominican Republic with 10,000 followers on Facebook, their most popular social media page.
