During her studies, Marianne volunteered with Pro Bono Students Canada. This earned her the Marie-Claude Landry award, given to the pro bono team from the Université de Sherbrooke Faculty of Law that has distinguished itself the most through its commitment to improving access to justice in the Eastern Townships.

Marianne also completed an internship with a large cloud computing company, allowing her to consolidate and build on her business administration skills. During her last semester of law school, she completed a clinic activity at the Superior Court of Québec.
