For the past six years, Casper has worked as a lawyer in a law firm specialising in corporate law and corporate criminal law. He obtained his master’s degree (cum laude) in 2017, after having completed both a bachelor’s degree in history and a bachelor's degree in law. During his studies, Casper worked at the Dutch public prosecution service and various law firms. He also volunteered at a legal clinic where he provided free legal aid in criminal cases. His master's thesis focused on the scope of Dutch money laundering legislation from a comparative law perspective.
