Heidi Winslow

Founder of Core - Heidi began working in the wellness world 3 decades ago at The Sports Medicine Institute in Aspen Colorado. She assisted Dr. Bruno Balke and Dr. Julie Anthony with stress tests while also working as a private trainer and PT assistant. Being a ski instructor and competitive runner, she was looking for effective conditioning techniques to share with clients. 

Her eagerness to find new ways to help clients rehab from injuries, combined with her curiosity about methods of strength training led her to study Pilates in Boulder, CO.  After a move to Telluride Colorado, she became the co-founder of Workout, a fitness studio, where she practiced Ashtanga yoga and created and taught  Core Connect Method classes, that incorporated moves from both Pilates and yoga for improving strength and flexibility. 

Moving to the east coast in 2006, Heidi began developing Core Retreats and opened Core Training. She also began her study and practice of mindfulness and meditation.  Wanting to bring the philosophy of Core to others for an optimal approach to wellbeing, she partnered with Emily McCavanagh and together they launched the first Core Retreat to promote mindful fitness, nutrition and meditation.
