Willie Ong

On September 21, 2021, it was announced that he will run for vice president in 2022 as the running mate of Manila mayor Isko Moreno. Ong left Lakas–CMD a day later after his announcement to run for vice president. He joined Moreno's political party, Aksyon Demokratiko, on September 25. On May 9, 2022, Ong lost in his bid to Sara Duterte placing fourth out of nine candidates. Ong conceded to Duterte on May 11.

Ong launched a bid to get elected as a Senator in the 2019 Philippine elections. His electoral campaign had a focus on health issues, particularly on providing a "holistic approach to providing total health care", leveraging on him being the "only doctor running for the Senate". Had he won, he would be the fifth physician to be elected in the Congress' upper house preceding Juan Nolasco (1931–1935), Jose Locsin (1954–1957), Juan Flavier (1995–2007) and Luisa Ejercito Estrada (2001–2007). Outside of health issues, Ong also expressed openness for the introduction of death penalty for heinous crimes, the lowering of the minimum age of criminal responsibility, and the adoption of federalism as the form of government for the Philippines.

Running on the banner of the Lakas–CMD political party, Ong said he did not rely on campaign donations to "avoid being indebted to anyone". Instead he relied on his online presence on Facebook and YouTube where he has 9.7 million followers and 1 million subscribers respectively as of March 2019. His campaign was also backed by 23 other pages with over 800 thousand followers and 28 groups with about 87.6 thousand members in Facebook. According to Ong's wife, some of these presence were managed by Overseas Filipino Workers (OFWs) who volunteered to support Willie Ong's campaign. Ong was also backed by other social media pages which supported other candidates backed by President Rodrigo Duterte's administration such as Imee Marcos and Bong Go.

He failed to win one of the 12 contested seats in the Senate finishing 18th in the polls with 7.5 million votes. According to his wife, they spent around ₱500,000 on his personal campaign. Counting only votes by OFWs, Ong ranked second behind Bato dela Rosa.

He has also worked as a consultant with the Department of Health from 2010 to 2014. Ong also established the Co Tec Tai Medical Museum in Pasay, named in honor of his father and reportedly the first medical museum in the Philippines. The museum documents the history of healthcare in the Philippines.

Ong was also a resident doctor and host at DZRH's public service program Docs on Call from 2009 to 2017.

Ong started maintaining an online presence when he set up a YouTube channel in 2007 where he posted video health tips. According to Ong, he first started to have presence in Facebook in 2012, when mainstream media outlets posts the medical advice articles he wrote for them on the social media platform. In 2013, Ong approached an impersonator who maintained a Facebook page with at least a million followers under his name and likeness and ask them for advise on how to "get more followers". He then went on continuing to produce articles.

In 2005, Ong became part of RJTV where he produced his own television show. From 2008 to 2018, he made appearances on ABS-CBN's Salamat Dok. He did not have a regular segment on the television show and only participated as a volunteer. He left Salamat Dok in October 2018 to pursue an electoral bid for the Senate in 2019. Ong also wrote for The Philippine Star and its sister publications, Pilipino Star Ngayon and PM PangMasa as a columnist.

For his elementary and high school education, Ong attended Xavier School in San Juan, Metro Manila. He studied botany at the University of the Philippines Diliman and then earned his medical degree at the De La Salle Medical and Health Sciences Institute, which was then the College of Medicine of De La Salle University, in 1992.

Ong is married to Anna Liza Ramoso, who is also a physician. They first met each other in 1992 while Ong was working as an intern at San Juan De Dios Hospital and got married a year later. They have two daughters.
