Name Partners

Gregorio R. Castillo

Gregorio R. Castillo spearheaded the move to form the firm in 1981. Few in his time had the qualifications and the leadership to launch such an ambitious project. Graduating cum laude and valedictorian of his class (U.P. Law ’57), he achieved the rare feat of also placing first in the bar examinations of the same year. After an LLM from Yale University, he joined SyCip Salazar, the country’s biggest law office, where he eventually became the youngest partner in 1975.

It was his dream to organize a firm in which competence alone was needed to succeed, where fairness would be the primary rule in the relationship among partners, where one could feel a sense of belonging as in a family, and where, above all, clients would get the loyalty and protection they deserve.

The result of this and the other founding partners’ efforts is the full-service firm that ranks among the country’s best today.
