Founding Lineage
A legacy of trial advocacy built across generations
The firm was founded by the late Mario E. Ongkiko, recognized in the Asia Pacific Legal 500 as a leading trial lawyer.
Under his guidance, the practice grew into one of the country's most respected dispute resolution firms, representing clients in matters that reached the highest tribunals in the land.
Among those the firm has had the privilege to represent are former President Corazon C. Aquino, former Speaker Jose V. De Venecia, and former Solicitor General Raul I. Goco.
