Heidi Winslow - Principal & Founder

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.  She studied and practiced Ashtanga yoga and created and taught  the Core Connect Method class which incorporates moves from Pilates, Bare and Yoga for improving strength and flexibility. 

Moving to the east coast in 2006, Heidi began developing Core Retreats and opened Core Training. She met Bob Cooley and was fascinated with his unique and effective development of resistance stretching & strengthening, which she continues to study at TGOF, and practice. She also began her education and training of mindfulness and meditation.  Wanting to bring the philosophy of Core to others for an optimal approach to wellbeing, she partners with other talented, inspirational instructors and teachers to create successful, meaningful workshops and retreats in the US and abroad. The Core team is always growing and expanding.
