Dionne Avocats is a family law firm on Montreal's South Shore, founded by Marie-Claude Dionne in 2014 and practising almost exclusively in family law. After a decade based in Boucherville, the firm moved to a mostly remote, telework-based model, with in-person meetings available by appointment in Brossard or at courthouses in the greater Montreal area.
