Over the course of a decade, OMA has followed a unique path in contemporary art, representing young and emerging artists. Originally from São Bernardo do Campo, São Paulo, the gallery has been involved with the local community, promoting actions in direct dialogue. In 2022, the original space was transformed into collective studios, and the gallery began operating in Jardins, a neighborhood in São Paulo. Recognizing the transformative role of art, OMA expanded its operations with OMA Cultural and OMA Education, seeking to reach a wider audience.

OMA participates in local art fairs and is in the process of going international. Artists represented by the gallery have been included in the collections of important institutions such as Pinacoteca de São Paulo, MAR, MAM, Museu Nacional de Belas Artes and CCBB.
