Deportivo Viedma

In 2009, "Club San Martín", promoted to Liga B, the third division of Argentine basketball. Due to its financial problems to solve the costs for taking part in a senior league, San Martín decided to merge with other two clubs from the city of Viedma, Villa Congreso and Sol de Mayo. The new institution was named "Alianza Viedma" to symbolize the allianz of three clubs.

Just two year after its establishment, Alianza promoted to Torneo Nacional de Ascenso, the second division of Argentine basketball. The club affiliated to Asociación de Básquet Valle Inferior and Federación Rionegrina de Básquet, with the purpose of registering its name officially.

During the 2011-12 season, Alianza reached the semi-finals, where they lost to Argentino de Junín in the 5th. game after two wins for each squad. The team made a great campaign playing at its home venue, where remained unbeaten for 19 consecutive fixtures.

Due to a sponsorship deal, the club changed its name to "Ceferino Alianza Viedma" in July 2012.
