Nancy & BillyNancy & Billy Greer

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!

Nancy Greer

With her BS in Social Work and experience as an educator, Nancy worked for over 15 years with the developmentally disabled and also started her own educational support company and mail order book business. She and Billy started studying Northern ShaoLin Kung Fu in 1987, but her training was interrupted by the birth of their son, Glen. When she returned to training, she focused primarily on tai chi, but also spent years studying yoga. Jing Ying Institute has enabled her to satisfy her desire to serve others in the community while also improving herself and educating others. She organizes our charitable efforts and we have raised tens of thousands of dollars over the years along with collecting several thousands of pounds of food and clothing. She is well known for her fundraising efforts in the local community and has come up with unique ways to create win-win situations in which a business that donates to her efforts also gets publicity and good exposure. In 2013, her efforts were recognized with an ASPIRE Community Leadership Award at a presentation that also happened to be the then-new County Executive Laura Neuman's first public event! She is very active in the local business community, often going out of her way to help other business owners. She follows the philosophy of giving first rather than asking. Her efforts resulted in the Severna Park Chamber of Commerce recognizing her as their "Women in Business Champion of the Year" for 2012. She also went on to win the 2012 Maryland Small Business Association's award for Women in Business Champion of the Year. She is President of the Greater Severna Park and Arnold Chamber of Commerce, and is also a chair of the Successful Women in Business Group where she arranges speakers and other activities.

Nancy wears many hats and you may see her in the office, in tai chi class, organizing our summer camps, leading our latest charitable campaigns, or out in the community visiting businesses or attending events.
Shifu Billy

Shifu Billy

Jing Ying Institute

Within a few minutes of speaking with Shifu Billy, it becomes clear that he is passionate about what he does and determined to help others succeed. His background as a scientist, his studies in biology, his experience teaching and his pursuit of studying martial arts provide him with unique skills as an instructor. Not only can he demonstrate a movement and explain its purpose, he can analyze it and break it down to a step-by-step process that makes it easier for others to learn. His holistic approach to instruction helps ensure students understand movements combining mind, body and spirit.

He has given presentations for hospitals, schools, colleges, government agencies, churches, business groups, scouts and more. He has appeared on the Diane Rehm Show, the Marc Steiner Show, the DC Cupcakes episode "So You Think You Can Lion Dance", and has been featured in the New York Times, Baltimore Sun, and Washington Post as well as local papers such as the Capital, and Severna Park Voice. Shifu Billy has had a long career of competing and teaching. Here are some dates for the start of his training, competing, and teaching:
  • 1973 - began training and competing in the martial sport of folkstyle wrestling (to 1981 when he finished college)
  • 1976 - began teaching gymnastics to children 5 to 16 for the Virginina Beach Department of Parks and Recreation
  • 1987 - began studying Tian Shan Pai Kung Fu (Northern ShaoLin) under Mfundi Tayari Casel at the Dennis Brown ShaoLin Wushu Academy

Shifu Billy also gained valuable coaching experience as the team captain of his high school Cross Country, Wrestling and Gymnastic teams as well as his college Cross Country and Wrestling teams. When the first kung fu school he and Nancy attended closed, he started a club and organized and led classes. During his laboratory career, he trained new employees locally, and also provided training for other locations nationally and internationally. In addition, he has taught credit and non-credit courses for Anne Arundel Community College including martial arts and tai chi. He also has over 15 years experience working with the developmentally disabled for Bello Machre and the ARC of the Chesapeake.

He started at Jing Ying in 2001, later continuing his studies in Tian Shan Pai kung fu with Mary Martin, Scott Dunmeyer and Sean Marshall. In 2005, he had the good fortune to begin training directly with Grandmaster Willy Lin, the person who first brought Tian Shan Pai Kung Fu to the US. Grandmaster Lin asked Shifu Billy to become his formal indoor student and he went through a traditional BaiShi ceremony to become his Disciple and a Third Generation inheritor of Tian Shan Pai.

Shifu Billy also was fortunate to study Tai Chi directly with Grandmaster Chen ZhengLei in the US and in China. Grandmaster Chen invited Shifu Billy to become his indoor student and he underwent a traditional BaiShi ceremony to become his Disciple and a 12th generation inheritor of Chen Family TaiJiQuan. Shifu Billy had the opportunity to visit the birthplace of TaiJi in Chen Village and study at the Chen Village training Center. He has also participated in many intensive training camps that Grandmaster Chen holds specifically for his disciples.

Through his close relationship with these and other high-level martial artists, Shifu Billy has been able to arrange workshops with some of the top coaches in the world at Jing Ying on a regular basis.

Shifu Billy has won numerous gold medals in forms, weapons, sparring, tai chi and push hands at local, regional, national and international competitions. He is one of those rare competitors who can win gold with a soft tai chi form, or a dynamic kung fu form, and then apply the priciples against another person to win push hands and free sparring all in the same tournament. He has also been on the other side of the competition ring serving as a judge. A few highlights include:

  • 2005 Grand Champion of the USA National Open Martial Arts Tournament winning gold in sparring, tai chi, and forms
  • 2009 USA WKF National Champion in advanced sparring and advanced Chen Style Tai Chi
  • 30th Anniversary Capitol Classics China Open - Head Judge, Internal Division
  • 2014 USAWKF Traditional Team Trial - Head Judge, selecting US representatives for the 6th World Traditional Championship in China.

In addition to special training with Willy Lin and Chen ZhengLei as a Disciple, Shifu Billy has also been fortunate to have the opportunity to train with Chen XiaoWang, Chen XiaoXing, Zhu TianCai, Wang HaiJun, Chen Bing, Chen ZiQiang and others.



Glen Greer

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 Greer

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 trained with Willy Lin, Chen ZhengLei, Chen XiaoWang, Wang HaiJun and others.

She has her BSN and works as an ER nurse.
