Vernon is the co-founder and editor-in-chief of VISOR. He started his career in automotive journalism in 1995, when he joined a local publication called Automotion as editorial assistant. He wrote for the motoring section of Philippine Daily Inquirer from 1998 to 2001, before launching a new car magazine he named Rev, serving as its EIC from 2001 to 2003.
He handled the motoring section of The Manila Times from 2003 to 2005, and then moved to Top Gear Philippines in February 2006. He was the latter's EIC until September 2, 2016, when Summit Media's management finally got tired of his brilliance.
He also penned a motoring column for Esquire Philippines from 2011 to 2012, but was dropped when the editors realized he wasn't fashionable enough. He has likewise dabbled in television, having occasionally appeared on GMA News TV's Turbo Zone.
Vernon is also currently a columnist for the motoring section of Business World, in spite of his aversion to business suits. He is well aware he won't get rich writing about cars. He doesn't mind—he just hopes to save enough to afford repairs for McKing, his 11-year-old hatchback.
