ETSI Technologies now 100% Filipino-owned


MANILA, Philippines – Popularly known as “ETSI”, the Company is now completely taken over by Filipino investors as of Nov. 28, 2014.

Being around for 33 years and still progressing, ETSI boasts one of the richest experience in and has continued in bolstering the growth and advancement of the local telecommunications industry. Its strength lies on competent Filipinos complemented by the proven technical expertise of former strategic partners such as Siemens (1982-2007) and Nokia (2007-2014).

ETSI has built a vast majority of the country’s fixed, mobile, fiber-optic and data communication networks and was the first to be entrusted with a large-scale outsourced service for mobile network optimization, operation and maintenance. It was also the first company to establish a high-level software research and development center in the Philippines inaugurated by His Excellency President Benigno S. Aquino III in July 11, 2011.

Under its newly-founded independence, ETSI plans to serve a much wider market in terms of industries & enterprises, solutions and geography. It will continue its core business in enhancing and developing telecommunications services while expanding to other promising fields by capitalizing on its proven Engineering & Project Management expertise.

ETSI has always been committed in delegating Filipino talents in all its projects including those with its past partners– as in the case of Siemens and Nokia– globally. With its accreditation and licenses from the Philippine Contractors Accreditation Board, Philippine Overseas Construction Board and Philippine Overseas Employment Administration, ETSI envisions an extensive increase in its talent deployment here and abroad.

Atty. Romarie G. Villonco, Chairman and General Partner of Siguion Reyna, Montecillo and Ongsiako Law Firm, is now the Company’s majority shareholder and will remain as the Chairman of the Board while Mr. Cesar Jacinto V. Castro II, the former SVP & GM of Siemens Philippines and Country Director of Nokia Siemens Networks Philippines, will serve as President & CEO.
