Regina Ongsiako Reyes was a Filipina lawyer, public servant, and business executive whose life traced an unusual arc — from the youngest solicitor in the history of the Philippine Office of the Solicitor General to an elected congresswoman of Marinduque, and later to corporate leadership and advocacy work. Born into one of Marinduque’s most prominent political families, she combined elite academic training at Georgetown University and the Ateneo de Manila with a career that crossed law, legislation, business, and philanthropy.
Her political moment arrived in May 2013, when she won the lone congressional district seat of Marinduque and took her place in the 16th Congress of the Philippines, where she served as vice-chairwoman of the House Committee on National Defense and Security. After her congressional term ended in January 2016, she moved into the private sector as President and CEO of two companies, served as First Lady of Batangas alongside her husband Governor Hermilando “Dodo” Mandanas, and devoted herself to charitable work with Gawad Kalinga and ANCOP USA. She passed away on May 5, 2022, in Makati, at the age of 57.

Regina Ongsiako Reyes Career
Regina Ongsiako Reyes’s academic record was remarkable from an early age. She was twice accelerated in school, became a Dean’s Lister, and completed her BS in Foreign Service at Georgetown University before earning her law degree (LL.B) with honors from the Ateneo de Manila University. She went on to pursue advanced studies in Comparative Law and was admitted to the Philippine Bar, as well as becoming a member of the State Bar of California and the Federal Communications Bar Association in the United States.
Her legal career began at the Office of the Solicitor General of the Philippines, where she earned the distinction of being the youngest solicitor in the institution’s history. She then served as Provincial Administrator of Marinduque — the island province where her family had deep roots. Her father, Edmundo Reyes Sr., had served as commissioner of the Bureau of Immigration, while her mother, Carmencita O. Reyes, had been governor of Marinduque.
Reyes’s highest political office came in May 2013, when she was elected Representative of Marinduque’s lone congressional district. She served in the 16th Congress of the Philippines from June 30, 2013, to January 12, 2016. During her tenure in the House of Representatives, she held the position of vice-chairwoman of the Committee on National Defense and Security and sat as a member on numerous other committees — an unusually broad committee portfolio that reflected her legal training and her interest in national affairs.
Her congressional term ended in January 2016, but her career continued on a new track. She moved into the corporate world as President and Chief Executive Officer of Montemaria Asia Pilgrims, Inc. and Abacore Capital Holdings, Inc., taking on senior leadership roles that drew on both her legal expertise and her public-sector experience.
From 2016 to 2022, she also served as First Lady of Batangas alongside her husband, Governor Hermilando “Dodo” Mandanas. In this role she lent her name and energy to advocacy and charity. She was active with the Gawad Kalinga Special Projects Group and with ANCOP USA, organizations focused on building children’s rehabilitation centers and supporting poor families — work that rounded out a life spent, in different arenas, on public service. She remained active in these roles until her passing in Makati on May 5, 2022.
