SUMAC started as a residential and commercial building firm in Chicago in 2002.

Although it has been awhile since we ran carpenters remodeling and building houses in Chicago, it was those experiences that led us grow into international projects, and today, to be simultaneously designing and supervising projects in Miami, Chicago, Antofagasta, Buenos Aires and Lima.
