Vancouver native Teryl Rothery began her entertainment career as a dancer at age 13 when she performed in her first musical, Bye Bye Birdie. She made her first television appearance five years later on a CBC Halloween special.

After performing voiceover work for the English-language version of the popular anime series Ranma ?, she made her telefilm debut with the Christopher Reeve drama Mortal Sins ? the first of more than two dozen made-for-TV movies in 10 years. Her theatrical features include the family films Andre (1994) and Magic in the Water (1995), Masterminds with Patrick Stewart (1997) and Best in Show (2000).

Rothery's many television credits are studded with SF series. She notably played the lead guest star in a classic second-season episode of The X-Files, Excelsius Dei, and has appeared on Showtime's Jeremiah (appearing twice as Mary, the hero's mother), M.A.N.T.I.S., So Weird and the SCI FI series First Wave and The Outer Limits (the episode Re-Generation), along with providing voices for the animated Exosquad, Dragon Ball Z and Robocop: Alpha Commando. Other TV credits include episodes of The Commish, Viper, Glory Days, The Chris Isaak Show and the Canadian hit series Da Vinci's Inquest.

In addition to her recurring role as Dr. Fraiser, Rothery also provided the voice of the Asgard Heimdall.
