Nicholas David Chamberlain was born on April 5th, 1963, in Boston, Massachusetts. After returning to England with his parents, Dr. Chamberlain grew up in the countryside north of London. In 1978 he returned to the U.S. to finish high school and began his training in the Martial Arts. Achieving his Black Belt in Kenpo in 1979, he graduated in 1981 and opened his first school in Chelmsford, Massachusetts, that same year, teaching American Kenpo Karate. In 1982, he was fortunate to begin training in Seven Star Praying Mantis and Eagle Claw under Master Lo Man Biu, in Boston’s Chinatown district, and continued until Master Lo’s untimely death six years later.
In 1984, after completing an apprenticeship with Shihan Rocky DiRico, Dr. Chamberlain was accepted as a student under Professor Nick Cerio of Providence, Rhode Island. It has been Professor Cerio’s guidance that has been the driving force in shaping Dr. Chamberlain’s Martial Arts ever since. In 1985, Dr. Chamberlain’s rank was recognized By Master Ed. Parker, under the auspices of the International Kenpo Karate Association (I.K.K.A.), which at that time was represented by Professor Cerio in New England.
