Janet DeFeo’s interest in health and fitness can be traced back to her career in the medical field as a radiology and ultrasound technician.

Upon retiring to Delaware, Janet was introduced to Tai Chi and was immediately hooked. Since then, she has earned teaching certification in Tai Chi for Arthritis, Fall Prevention, and Qigong for Health from Dr. Lam’s Tai Chi for Health Institute. Janet also achieved teaching certification in Level One training in Qigong and Beginning Tai Chi Forms from the Silver Lotus Training Institute where she continues to study on a regular basis.

Lynne began training in Tai Kwon Do, an external or “hard” martial art, in 1998. After observing Tai Chi classes, though, she found herself captivated by the slow, flowing movement of the forms, so she switched to this internal or “soft” martial art. Lynne studied the Yang Long Form with Irv Wynn, whose teacher had studied with Cheng Man-Ching, widely recognized for being instrumental in spreading Tai Chi to the United States.   Since her move to Delaware, Lynne has been studying Qigong, Yang , Sun, and Fan forms with Susan Hamadock.   Lynne is a certified Tai Chi for Health Instructor and teaches the Yang 24 Form, Tai Chi for Diabetes, Tai Chi for Arthritis, and Qigong.  She is available for group and private classes.
