Four years ago, when she and identical twin sister Kyle walked into North Carolina's fencing room, Kyle said that the team would not accept two people who hadn't even picked up a sword.
But Kim was still very curious, and rejected Kyle's notion.
It was a rare move for Kim, who usually took Kyle's words to heart.
"My sister told me that I couldn't go (to fencing tryouts) because it's a varsity team," Treiber said. "But I was going to find out."
North Carolina fencing coach Ron Miller stepped in and made a believer out of Kim and Kyle, and used their athletic abilities to rebuild UNC's women's sabre division.
Now, Kim is one of North Carolina's most accomplished women fencers.
When Kim first picked up her sword, Miller was pushing for sabre to gain acceptance as an official weapon for women. Women only participated with the weapon as a demonstration sport during Treiber's freshman and sophomore seasons.
"Basically I promised Kim that I would either die first or get women's sabre as an official division before both of them graduated," Miller said. "It turned out that we actually got it a year sooner than we anticipated."
And Kim Treiber took advantage quickly, posting a long list of achievements in the two-year span. As a result, she was named first-team All-America her junior year and earned second-team All-America honors this year.
