Fund Development and Membership Coordinator - Crystal Mackenzie is a born and raised Calgarian.

Her post-secondary schooling focused on education and communication techniques, and she uses this to share her deep passion for water and watershed health. Crystal also runs a local literary magazine, and is a creative writer and editor, in her spare time.
