About Jean

Certified Pilates instructor, personal trainer, YUR Back™ licensed instructor, and certified Essentrics™ Instructor, Jean Deferrari offers her clients greater fitness, better function and an overall sense of well being.  Her fitness training philosophy concentrates on core strength, stability and focuses on the eccentric phase of training.  Her approach complements the body, making it more functional, improving its appearance and is great for injury prevention. 

Jean's story began after many years working as a personal trainer.  She enjoyed bodybuilding and kickboxing which were hard on her joints. Her training efforts paid off and helped her look good on stage in Fitness America Pageants in the 90's.  The external rewards of bodybuilding were apparent, but internally she was suffering from a sacroiliac joint injury and back pain.  Searching for other methods of training that would not be detrimental to her health, she tried Pilates in 1998. She realized how Pilates was the answer to her injuries and started doing Pilates to help rehab her injuries. Inspired by the precision and control of the Pilates method, she embarked in professional Pilates Instructor training seriously in 2001.  Over the years,  Jean has experienced the healing benefits Pilates offers.  Today,  Jean draws on a combination of 15 years of teaching Pilates, over 20 years experience of personal training and teaching group fitness classes, and her personal physical challenges to customize safe and challenging Pilates workout for her clients.
