Mackenzie St. Onge

Athlete Development Specialist


Mackenzie (Mac) St. Onge is a former Division 1 Ice Hockey and Rugby player, Dartmouth College graduate, and certified Athlete Development Specialist. Passionate about supporting athletes, she currently works for U.S. Olympic and Paralympic Committee (USOPC) as their Manager of Athlete Outreach & Engagement.

Mac is also the founder of The Sideline Perspective – a community based platform where injured and retired athletes can come together to find connection, share stories, and move forward with purpose. Through storytelling, interviews, and podcasts she has helped to shed light on the hidden challenges competitive athletes face when temporarily sidelined or no longer able to compete.

In her work across various sport organizations, Mac hopes to make an impact on the culture of athletics in the United States - promoting whole athlete development and high performance as two parts of the same whole.

Mac lives in Park City Utah with her husband and loves to try new sports/activities, most recently including: climbing, wake surfing, and mountain biking!
