He was raised in Hudson after emigrating from Portugal at the age of 5. He attended local schools and was a 1969 graduate of Hudson High School. He later received his Bachelor's degree in 1973 from Worcester State College. Dennis eventually earned his Master's degree and was currently working on his Doctorate's degree.
He was employed as a language teacher and later a guidance counselor in the Hudson Public School System until his retirement in 2011. He was a member of the Hudson Portuguese Club and Saint Michael's Parish in Hudson.
Dennis had many interests throughout his life, including traveling. He spent 28 summers in Madrid, Spain furthering his education but his passion in life was dancing. He truly enjoyed the art of dance and loved to share his talents as an instructor at many levels. He taught dance classes both privately and publicly at many local venues including the Hudson Portuguese Club and night classes at Assabet Valley Technical High School. In the 1970s and early 1980s, he taught dancing at the Joy of Movement Dance Studio in Cambridge and was well known as the Dennis C. Frias Dance Co.
