William R. Ambrosia
Bill Ambrosia-Cerio started training in the martial arts in March of 1973 with Nick Cerio and Nancy Cerio
at the Cerio’s Academy of Martial Arts in Warwick, RI. Nancy and Nick are his mom and step-dad
Through the years Bill competed actively in tournaments up and down the east coast, amassing quite a few
trophies. As a youngster, he was recognized by the U.F.M.A as a Junior Forms and Sparring Champion. He
was awarded the title of the 1976 Champion in each of these divisions.
In 1978, Nick and Nancy Cerio formulated the RI Amateur Kickboxing Union. This organization
concentrated on promoting kick boxing matches in the New England area. Bill began his kickboxing
training at age 12. He worked out in a group of kickboxers that ranged from 18 to 26 years of age and held
his own. During 1978 through to 1980, Bill participated in exhibition bouts at some of the kickboxing
events. The Kickboxing union ran events on Friday evenings and called them “Friday night at the Fights”, a
take-up on the ones that were broadcasted during the 1950's.
In 1983, Bill tested and passed his Shodan test. He was 17 years old at the time. Normally the lowest age
limit was 16. But because he was Nick Cerio & Nancy Cerio’s son, he was kept back so that no one would
be able to say that he was “given” his belt because he was their son. It was July 29th, it was 95/ outside and
we had no air conditioners at that time. Needless to say that it was an endurance struggle and not one
complaint from those testing that day.
Bill continued training and competing until he was involved in a serious auto accident (hit head-on by a
drunk driver). The doctors said that he would never be able to do martial arts again as his right knee was
shattered. After recuperation from the preliminary surgeries, he began working out and training harder,
roping 1, 2 and 3 minute rounds on only one leg. After approximately 7 surgeries and extensive physical
therapy, Bill recovered and proved the doctors wrong. Doctors rarely, if ever, seem take into consideration
the human factor!
Also an IT specialist, Bill opened his own business as well as worked for numerous well-known computer
firms. In addition, he married in 1997 and began raising a family . He has 3 children, Hannah, Nick and Julia.
Currently, Bill free-lances as an IT specialist and teaches martial arts at the Cerio Ambrosia Martial Arts
Center in No. Kingstown, R.I., as well as traveling and teaching seminars.
