We started as a professional firm in 1973, with the personal name of CPA Jesus Mario Treviño Sepúlveda.

We established the Office Sepúlveda Treviño S.C.

Together with the firm Zambrano y Compañía we formed a strategic alliance: Sepúlveda Zambrano, S.C.

We became an independent member of Polaris International, a leading association of independent Accounting firms worldwide.

Polaris International and IGAF Worldwide merged, and became IGAF-Polaris.

There was a major change in the signature of the firm. In 2012, we became Traust Accounting & Legal Firm. In addition, our association converted into PrimeGlobal, the third association of independent Accounting firms worldwide and the largest in Latin America.
