Orley won the 1983
Girls Amateur Championship and played college golf with the
Duke Blue Devils at
Duke University in Durham, North Carolina where she won the 1985 ACC Championship individually. She turned pro in 1990 and won twice that year, claiming the Singapore Ladies Open and the Swiss Ladies Classic, her native country's national championship, the highlight of her career. In 1991 she was runner-up at the
Ladies English Open after losing a playoff with
Kitrina Douglas, and in 1992 she was runner-up at the
Ford Ladies Classic. When she missed 19 of 20 cuts on the
1993 LPGA Tour, Orley started planning for a future outside of golf. She returned to LET and was runner-up at the 1995
Costa Azul Ladies Open, but soon retired from tour and became a sales director for an investment management firm. Orley regained her amateur status in 2002. She turned 50 in July 2016 and played the
U.S. Senior Women's Amateur, returning to competition golf after a 20-year hiatus, with
1988 U.S. Women's Open-winner
Liselotte Neumann as her caddie. The qualifier where she shot 72 to earn to earn medalist honors was her first competitive round since retiring from tour. ==Professional wins (2)==
