Mary Sullivan Kelly

Owner/Instructor

Mary opened True Pilates Boston in order to bring authentic classical Pilates to the area.  Her goal is to provide a supportive and challenging environment that honors Joseph Pilates' intent: "complete coordination of body, mind, and spirit."

Mary is passionate about the Pilates method and the benefits it provides people from all walks of life and at all levels of physical fitness. She is awed by the many ‘light bulb’ moments this system provides, and the opportunity to see an exercise each day from a new vantage point. Mary has always enjoyed movement, or at least being on the move. That said, her dance background is more Elaine Benes than Martha Graham.

Mary is certified by Romana's Pilates, and trained with the world-class instructors at True Pilates New York who employ techniques that are as close to the original teaching of Joseph Pilates as are available anywhere. She is a graduate of the comprehensive Pilates Professional Advanced Teacher Training Program - The Red Thread, as well as the Advanced Contrology Program through Authentic Pilates, The Pilates Studio Portugal. She regularly attends workshops and conferences to further her appreciation and application of the method. She also holds a BA from Simmons College and an MBA from Boston University.

NANCY HORNE

INSTRUCTOR

Nancy started her Pilates journey a decade ago to alleviate the physical strain of frequent business travel. Subsequent auto collisions introduced her to the powerful role Pilates can play in healing the mind, body, and spirit.

Nancy is certified through Power Pilates.  She holds a BA in American History from Harvard College and an MBA in Marketing from Columbia University. She lives on a pond in Wellesley, MA. When not teaching Pilates, Nancy is a business consultant specializing in Strategic Marketing and Product and Service Innovation.

ANTONIO ANIELLO

Instructor

Antonio’s Pilates journey began in college in 2004 when he was playing D1 tennis and looking both for ways to gain a competitive edge, as well as to allow his body to adapt to the stresses he encountered on the tennis court.  Given his athletic background, he loves to layer the coordination, precision, and strengthening tenets of classical Pilates principles into his teaching.

After a summer of playing APT satellite tournaments, he hung up his racquets and found a desk job.  When it became clear sitting behind a desk wasn’t going to work out, and he followed his passion, got certified and never looked back. 

Antonio completed the New York Pilates Studio teacher certification through the United States Pilates Association, and is also a vinyasa yoga and Yin yoga teacher, finding the calming and meditative elements of yoga to help his students by giving them an enhanced physical awareness and confidence. 

He lives south of Boston and shares 15 acres with his girlfriend and three goats named Michael Jordan, Serena Williams, and Alton Brown.
