While at the helm of Food For All New Brunswick, she built a robust network to activate and amplify food security.
Laura lives near the Ottawa River in Orléans with her partner and their two children. Originally from Sackville, New Brunswick, Laura grew up very connected to water: canoeing on the lake in her backyard, swimming on the beaches of the Northumberland Strait, and mudsliding on the Bay of Fundy mudflats. She speaks four languages and loves to cross-country ski.
