Reddick began her successful curling career by winning the 1999 Ontario provincial junior championships. At the 1999 Canadian Junior Curling Championships, Reddick skipped Ontario to an 8-4 record, just out of the playoffs. Reddick was still eligible for Bantams that year, and she won the 1999 Bantam Girls provincial championship as well.
Reddick won another provincial junior championship in 2000. Again, her Ontario team finished with an 8-4 record, and once again it would not be good enough to make the playoffs.
Reddick won her third provincial junior championship in 2002. At the Canadian Juniors that year, her team finished with another winning record, this time 7-5, but again they fell short of the playoffs.
Reddick would also find success in Mixed curling. In 2000, she played third for John Epping, winning the provincial mixed junior championship and repeated the title in 2002 when she played third for Sebastien Robillard. Reddick would then win back to back Ontario Mixed titles in 2006 and 2007 throwing third stones for John Epping. The team won the 2006 Canadian Mixed Curling Championship, but were unable to repeat in 2007, finishing 6-5.
