Natasha was born and raised in Dartmouth and grew up in a family of entrepreneurs.

Early on, this impacted the way she viewed sustainability and the impact we were having on our beautiful planet. Two children later, the urgency and passion for the outdoors and protecting its beauty continue to grow. Professionally, Natasha has worked at both the provincial and national levels of sport for over 18 years, including working as a full-time snowboard coach for seven of those. Now in the final stretch of her MBA in leadership, she’s passionate about driving positive change in sport, the community she resides in and beyond.
