Master Wasil, starting in 1960, trained for 23 years with Grandmaster Feeman Ong. He instructed in Parma for Master Ong from 1962 through 1964 and in Cleveland from 1965 through 1968. In 1970 Master Wasil was appointed by Master Ong to be the director of Wing Sing School of Kwan Ying Do. Both inside and outside of classes he spent a lot of time with Master Ong and was always eager to learn more about every aspect of the art. Master Wasil has always been known for his rigorous workouts and diligent training as well as his tremendous power and fighting ability. Master Ong, after receiving the consensus of his Oriental Masters, appointed him as "jon moon" or person designated to carry on the lineage of the Kwan Ying Do system. Earning the highest rank that anyone in the system obtained (3rd degree black belt), he continually trained under Master Ong until his passing.
Besides the hardstyle, Master Wasil also learned many other aspects of the art from Master Ong. He trained in and gained a high level of skill in land reading (feng shui). Master Wasil often would verify his reading of a property with Master Ong's reading. Face reading was also one of Master Wasil's strengths. Through his unique insight into T'ai Chi and meditation and his understanding of these arts he has developed many health exercises and practices himself.
