Sprecher was born in Basel, Switzerland, to Priska, a Swiss-German schoolteacher, and Peter Osimadu, a Nigerian journalist.

[3] At nineteen years old, Sprecher was one of seven people selected worldwide to be accepted into the prestigious École nationale de cirque of Montréal.

She represented the school and its motherland Canada at the Wuqiao International Circus Festival (中国吴桥国际杂技艺术节) in Shijiazhuang, China with her Cloud swing act and won the Bronze Lion, which led to a guest-artist contract for the creation phase and the 3-year North-American tour of Cirque du Soleil’s Quidam.

[4] Due to Sprecher's background in the Circus arts - and especially due to her experience as a trapeze artist with Cirque du Soleil - she moved into the Hollywood stunt business and began her television and film career in the year 2001, when stunt coordinator and Second Unit Director Brian Smrz brought her in to perform comparable stunts— namely high Wire-flying, on Minority Report, starring Tom Cruise.

One of her most dangerous stunt performed to-date, is when she had to let herself get hit by a car on AMC's Feed the Beast, which aired August 2016.
