Dr. Desiree Walker has a firm grasp on the competition, literally.

The Lumberton, North Carolina dentist made her national-television debut on American Ninja Warrior, NBC’s extreme-obstacle challenge, which aired in June of 2014.

Incisal Edge dental lifestyle magazine interviewed Dr. Desiree Walker regarding her American Ninja Warrior debut.

The 35-year-old’s nemesis back then: her faltering grip on a rope, which led to what has been called by the show’s co-host Jenn Brown, “one of the most epic falls in the history of American Ninja Warrior.”

Invited back to compete in the seventh season (filming May 10 and 11 at Universal Studios in Orlando), Dr. Walker joked in an interview today with, “I’m seeking revenge on the course.”

The lifelong fitness enthusiast demonstrates that in her audition video, which she shares with loyal Flossers.

In addition to installing a rope climb in her private workout space at her practice, Dr. Walker is devoting the same level of commitment to her training regimen as she does to her dental patients.

“I have built more training obstacles – quintuple steps which I have stationed the parking lot of my practice – to train at lunch and after work- as well as get staff involved in the fun!” she said.
