Clark studied Business Administration at the Pontifical Catholic University of Chile (PUC). He later completed a Master of Business Administration (MBA) at the University of California in the United States.[6]
Clark began his professional career in finance at the Chilean branch of the BBVA, where he worked for approximately seven years in the Corporate & Investment Banking division. During this period, he held roles progressing from associate to vice president and director, focusing on corporate finance and capital markets.[6]
In 2011, Clark joined Penta Bank, where he led the «Debt Capital Markets» area for around four years, participating in structured finance and debt issuance activities in the Chilean market.[6]
After leaving Penta, Clark founded Redwood Capital, a financial advisory firm, where he served as chief executive. Through Redwood Capital, he provided advisory services related to investment and financing, including engagements connected to professional football organizations in Chile.[7]
Clark later served as a director of Sartor Administradora General de Fondos (Sartor AGF), a regulated Chilean investment fund manager.[6]
On 21 October 2021, Clark assumed the presidency of Azul Azul S.A.,[8] a Chilean sports company that operates the professional football team of Universidad de Chile since 2007. Azul Azul manages the club’s professional football activities through a concession agreement with the University of Chile, which retains ownership of the club’s name and symbols.[7]
On 18 November 2025, the Chilean Financial Market Commission (CMF) imposed administrative sanctions on directors of Sartor AGF, including Clark, in connection with regulatory breaches identified by the authority. The CMF ordered a fine of 65,000 UF and a five-year disqualification from serving as a director or principal executive in entities under its supervision.[9][10] Following the CMF decision, Clark stated publicly that he disagreed with the ruling and announced that he would pursue available legal remedies, while confirming that he intended to continue serving as president of Azul Azul.[11]
Representatives of the University of Chile stated that the institution would review its agreement with Azul Azul regarding the use of the university’s name and symbols.[12]
