HILARY HARTMAN
BUSINESS DEVELOPMENT
Hilary works in Business Development. She became involved with Cardio Sport 7 years ago, first as a participant. She is a long-time entrepreneur, with over a decade and a half of experience working to bring innovation to market.
From the moment she first walked into a Cardio Sport class led by John back in 2012, she knew she had to be a part of sharing it with the world.
Never before has there been a program that truly engaged the mind of athletes (and their bodies) like this program. As a long-time purpose-driven athlete herself, mainly with individual sports like snowboarding and white water kayaking, she couldn't get enough. Her passion was ignited and her mission to bring Cardio Sport to the world began.
