Grete Gryzwana was trained and certified to teach the Pilates Method by Joseph Pilates protégé, Romana Kryzanowska. Since 1996, from coast to coast Grete has taught numerous individuals from all walks of life. Professional and aspiring dancers, singers, athletes and numerous other individuals have relied on Grete’s expertise and experience to guide them toward optimum fitness through the Pilates Method.

"In 1995, I started doing Pilates after a severe car accident. Although I was dancing professionally and competing as an equestrian at the time of my injuries, I was amazed at how quickly Pilates helped me recover, and I surpassed my pre-accident strength and fitness.  This led me to pursue certification with Romana Kryzanowska and the Pilates Studio of New York. My plan was to integrate Pilates into the dance and fitness courses I was already teaching. I was accepted into the teacher-training program and as my apprenticeship began, I saw how the Pilates Method develops strong, flexible bodies in all walks of life, for a wide range of activities. Every client's strength, posture, focus, agility and flexibility improved. My plan shifted to sharing Pilates with all kinds of people. I've never looked back. Through the years I've had the privilege of guiding hundreds of individuals toward optimum fitness with Pilates. I continue to be inspired by the work, always learning and experiencing its benefits in new ways.  With each new client, overtime, I see the genius of Joseph Pilates at work."
