The firm SANZ-DAZA ASESORES was founded in 1948 by Carlos Sanz-Daza Suarez, who started the activity of the firm in the field of accounting and excise (alcohol and distilled beverages, remaining today as one of the specialties of the firm ), and gradually expanded his advice to all areas of taxation. His son and current director Carlos J. Navarro Sanz-Daza (economist) later joined the firm, and so has done more recently Carlos Sanz-Daza Espí (lawyer and economist), grandson of the founder and the third generation providing advisory services.

SANZ-DAZA ASESORES has distinguished itself from the beginning by a continuous development marked by the expansion and improvement in the quality of the services provided. This has been possible not only by the several Sanz-Daza generations, but also through the successive incorporations of several professionals (lawyers, such as Jorge-Luis Lado Gual; and accountants, such as Emilio Sanjuán Ubeda). Therefore, the firm is currently in a position to offer advice to businesses and individuals in various fields such as accounting, taxing, litigation, commercial and administrative law.

Only one thing has not changed since the founding of the firm: its values​​. These values ​​are:

 -  Honesty.

 -  Customer focus.

 -  Personal and professional excellence.

 -  Adaptation to change.

The trust of our customers is our best asset. The best proof is those early customers who still honor us with their confidence since the foundation and those who have joined us through the years.
