 In all her accomplishments, being a member of the very first Canadian Olympic games team in Barcelona in 1992 is one of her biggest thrills.    A highlight in Denyse’s career was when she made the quarter-final in doubles with partner Johanne Falardeau at the prestigious All England in 1984 and the quarter- final at the Japan Open in 1986 again with partner Johanne Falardeau.
