About Pilates
​
German born, Joseph Pilates emigrated to the United States in 1926. He set up shop in New York City, teaching his method of physical fitness, that he coined "Contrology" based on the principles of Breath, Concentration, Centering, Control, Precision and Flow as well as elongation, oppositional forces, uniformity, balance and strengthening. He quickly became the guru of rehabilitation to dancers, and a fitness authority to celebrities and the general public alike.
Spheeris Pilates is proud to continue Joseph's work in primarily what is known as the original classical repertoire. Joe's method has proven to be effective, safe and viable throughout over 90 years of practice by certified and trained professionals all over the world.

NORIKO TANI
I came to Summit County from Hanover, NH. I've been teaching Pilates, Skiing, Aquatics, and Spinning since 2013. I'm also a Physical Therapist Assistant since July 2020.
I started practicing Pilates from an article in a newsletter around 2000. There were 10 or so exercises and I did it as a warm-up before my workout. A year or so later, I realized that I had not felt any back pain that had bothered me occasionally since 1988. So, I kept doing them as it felt good. Later, I met a Pilates instructor, kept learning more and more, and became an instructor.
Pilates education and certification: STOTT Pilates Level 1 certified instructor for Mat, Reformer, CCB(Cadillac, Chair, and Barrels), Merrithew™ Fascial Movement, and ZENGA®.Taught at River Valley Club in Lebanon, NH and Woodstock Athletics Club in Woodstock, Vermont.
