Geoff Molson spent his childhood in Montreal and was a passionate Canadiens fan from a young age, when Molson Brewery owned the team.

Prior to entering university, he took his first steps in the family business by working in sales at the Molson Brewery during the summer. In 1992, he earned a bachelor's degree from St. Lawrence University in Canton, NY with a multidisciplinary major in economics and French and Canadian studies. He then joined Coca-Cola in Atlanta as Assistant, Global Media Services, where he was responsible for developing international media strategies. He would later attend Babson College in Boston, completing a master's degree in administration (MBA) before working in both Manhattan and Boston as a principal consultant with the CSC Consulting firm.

He returned to Molson Brewery in 1999, working first in Toronto as a chain account sales manager, then moving on to Denver, where was named a VP in charge of managing the Molson USA business. In 2005 he came home to Montreal to serve as VP, Marketing for the company, playing a strategic role in brand development and in strengthening partnerships with key stakeholders. During this period, he also served on the board of directors of Molson Coors Brewery and Res Publica.

In 2009, he became Chairman of the Board and Ambassador of Molson. That same year, along with brothers Andrew and Justin, extended members of the Molson family, and partners including BCE Inc., the Woodbridge Limited company, the Fonds de solidarité FTQ, the National Bank Financial Group and Luc Bertrand, Geoff helped lead the acquisition of the Montreal Canadiens, the Bell Centre, and evenko, the organization’s entertainment division. That ownership group became formally known as Groupe CH shortly thereafter; Geoff has been President and CEO since 2011.

In returning to an ownership position of the Montreal Canadiens, Geoff continued a long tradition that has made the Molson family synonymous with the team for three generations. To increase the company’s involvement in culture and entertainment more broadly, he added another pillar to its portfolio by acquiring L'Équipe Spectra in 2013. The entertainment component of Groupe CH now includes six festivals and management of seven venues. Under Geoff’s leadership, the Canadiens brought the Rocket, the club’s AHL affiliate, to the newly-opened Place Bell in Laval in 2017.

Strongly committed to the local community, Geoff is a member of the Molson Foundation, the Montreal Canadiens Children's Foundation, the St. Mary's Hospital Foundation, and a member of the L'Heure Est Brave philanthropic campaign of the Université de Montréal. He is also a Knight of the Order of Canada and the National Order of Quebec since 2019. He and his wife Kate have four children: Henry, William, Tom and Maggie.
