Above all else, Kathryn considers motherhood her most precious calling — though she is best known worldwide for her contributions to dance and the classical Pilates method.
Her Pilates journey began at age fourteen, and she started formal Classical Pilates training in 1982. Over the years she had the rare privilege of studying directly with First Generation master teachers: Romana Kryzanowska, Lolita San Miguel, Kathy Grant, Sari Mejia Santo, Jay Grimes, and Edwina Fontaine. She went on to become a Romana's Pilates Level 2 Trainer and completed comprehensive training across multiple certification programs.
Beyond Pilates, Kathryn is a Guild Certified Feldenkrais Practitioner, served for ten years as a principal dancer with Ballet Hispanico of New York, and holds a second-degree black belt in Tae Kwon Do — a breadth of movement discipline that deeply informs her teaching.
Working closely with Romana Kryzanowska, Kathryn was named the founding Vice-President of the Authentic Pilates Guild. She remains the only woman to have demonstrated on both the Romana's Pilates Mat and Legacy DVDs, and has been featured in multiple issues of Pilates Style Magazine — gracing its cover for her 55th birthday.
An international educator, Kathryn has taught in countries across the globe and authored several books in the Red Thread series along with other publications. She created the Red Thread Method of Pilates, first introduced in the early 2000s, and each year personally selects teachers for PPATT (Pilates Professional Advanced Teacher Training). In 2022 she partnered with Balanced Body to produce the KRN Pilates — The Red Thread Method App.
My favorite thing in the world is to be able to teach the work I believe in so strongly, as my teachers so generously gave it to me.

Immersive Learning
The Red Thread Ranch
The Red Thread Ranch was created as a dedicated home where Pilates instructors can further their education in a safe, supportive atmosphere. Rather than simply observing, teachers learn by doing — receiving hands-on guidance from experienced instructors who have walked the same path.
The environment is intentionally intimate: small groups, deep study, and individual attention allow participants to refine their craft at a level that larger workshop settings rarely permit. Teachers who have attended consistently describe the Ranch as their “Pilates home away from home” — a place where the work is honored and growth is inevitable.
