Gerald started his career in the hit reality TV show Pinoy Big Brother Teen Edition. His transition from reality TV to acting in series and films was met with huge success because of his innate acting skills and charisma. Gerald is a flexible actor who can do hard-hitting action films and series like On the Job (2013), A Soldier’s Heart (2020), and show his soft and dramatic side on Budoy (2011) where he portrayed the character role of a mentally challenged individual that brought hope to the people around him. Gerald’s Budoy is one of the first Philippine advocacy series that represented in mainstream media the struggles of people with mental disability.
