Stephanie Steves


Like many Board Members, Stephanie began as a Park Ambassador, helping with tree planting, building the living retaining walls on Brae Island, and invasive species mapping & removal.


A lover of the natural world, volunteering grew a greater appreciation. After completing some training at the University of Fraser Valley in Accounting and Bookkeeping, an opening on the board presented another way to give back and help maintain balance.
