About Olivier

Olivier Roy-St-Jean holds a law degree from Université de Montréal, an aerospace engineering degree from Polytechnique Montréal, and a graduate diploma in management (DESS) from HEC Montréal, and is a member of both the Barreau du Québec and the Ordre des ingénieurs du Québec. Originally from the Lachute area in the Argenteuil region, where he still lives, his knowledge of the region and its residents is an asset to the firm. His earlier career in engineering and project management, including work in remote regions such as Africa and Nunavut, gives him a different perspective on his clients' concerns. Roy-St-Jean has worked with people from many cultures and backgrounds, informing a human-centred approach to client relationships, and he practises across a range of legal areas at the firm.
