Nancy and Billy Greer met in 1978 while attending neighboring colleges.
Nancy was a social work major and Billy was biology/pre-med. They
married in 1982 and have been full partners in each others lives ever
since and have worked together almost continuously. They have
exemplified the concept of Yin and Yang, bringing together skills and
ideas that complemented each other and enabled them to do more
than either might accomplish on their own. They are both passionate
about what they do, which is easy to see if you spend a few minutes
talking to them!

Tim began training in Kung Fu under Shifu Sean Marshall in February of 1999 at East West Martial Arts which later moved and became Jing Ying Institute. He started assisting in classes at Jing Ying in 2002 and started instructing in 2004. He earned his black sash in Kung Fu in July of 2006.
Tim is known for his rigorous workouts in class. He enjoys instructing because it gives a deeper understanding of the forms and the fighting aspects of Northern Shaolin Kung Fu. He also enjoy watching students progress from beginner to advanced levels.
He continues to train to improve flexibility, stamina and strength and to improve his self-defense skills.

Glen began taking PE classes at Jing Ying in the Fall of 2001. In the summer of 2003, he started the Kung Fu program. He likes to push himself to test the limits of his abilities and has seen big improvements in strength and flexibility. He's known for his sparse, efficient fighting style and powerful thrust kicks.
In the past, he ran our Kids Kung Fu classes and family classes. Although no longer actively teaching, he can still be found working out and helping out at Jing Ying as needed.
In his spare time, he enjoys reading, listening to music, weightlifting and watching movies.
Lane began taking PE classes at Jing Ying in the Fall of 2001. In the summer of 2003, she started the Kung Fu program. In 2004, she also started studying Tai Chi and finds that it is a wonderful complement to the Shaolin Kung Fu training. In July of 2008, she earned her Black Sash in Kung Fu.
She quickly fell in love with the physical and mental challenges of learning Kung Fu. When she started, it seemed like it would be hard to find time to train twice a week, but now she says it's hard to go for a day without Kung Fu!
Lane taught our Kung Fu Kids program, and organized and helped run the Demo Team. She finds that instructing others helps her gain a deeper understanding of the forms.
She is Jing Ying's most prolific medal winner with a national championship in advanced level sparring and in advanced level tai chi forms. She has won numerous other gold medals for sparring, forms, weapons and tai chi and is known for her flexibility.
She has her BSN and works as an ER nurse. Her busy schedule means she is no longer at Jing Ying 6 days a week, but she helps out in classes and in performances when she can.
