Triathlete, runner and outdoor adventurer who works by day as a Nurse Practitioner. With knowledge in health, nutrition and fitness, I love educating people to help them achieve their goals in a way that integrates into their lives both in the short term and in the long term.


Susie Kelly is a Nurse Practitioner and triathlete who has been coaching athletes since 2015. She joined APEX in 2016 as both coach and indoor cycling instructor.
