Mary Therese Cadorette was born on March 31, 1957, in East Hartford, Connecticut, United States. She started taking dance classes at the tender age of five and later entered dance competitions, crediting her love of dance for her career milestones.
Cadorette was crowned Miss Connecticut in the 1975 Miss America pageant and graduated from the University of Connecticut in 1979. She performed in dinner theatres, with the USO, and spent three and a half years on Broadway as an understudy in the musical "42nd Street".
In 1984, she landed the recurring role of Margaret Turner on the popular TV show Night Court. During the 1980s, she was also seen on a number of game shows, including The $25,000 Pyramid, Super Password, and Body Language.
Cadorette owned her own restaurant, Mary's Lamb, in Los Angeles in the 1990s, which was frequented by many celebrities. She has been in a few films, including Stewardess School and The Rat Pack.
In 1999, she left California and moved back home to Connecticut to take care of her mother who had suffered a stroke. Her mother died eight years later. Cadorette and two friends, whom she had known since they were in dance school as children, decided to take up dancing again after many years. They formed the "The Chapeau Rouge Dance Project" encouraging former (and older) dance students to attend classes in the dance studio that they have rented.
She was formerly married to Michael Eisen in 1982. Later, she married William Harris (born March 16, 1948),and went by the name Mary Cadorette-Harris. Her husband died on October 15, 2010.
In March 2011, Cadorette directed and choreographed "Hairspray" at Glastonbury High School in Glastonbury, Connecticut. In March 2012, she directed "42nd Street" at Glastonbury High School with some of the original choreography.
She teaches at the Greater Hartford Academy of the Arts Tap and Ensemble Class in Hartford, CT. She also owns and runs an antique store called "Nug and Bug Antiques & Collectibles", located at 114 West Granby Rd, Granby, CT 06035.
On November 1, 2015, she married her 7th-grade sweetheart Michael Daly and now goes by the name Mary Cadorette-Daly.
