Campbell is more than a fun loving, willful kid that loves to monkey around; she is capable of slipping into a broad range of roles so seamlessly and effortlessly that she has morphed into a much sought after commodity in the world of arts and entertainment. And she's still just in elementary school!

Born October 25th, 1995 in Vancouver British Columbia, Campbell demonstrated to her family from the earliest stages of her development that she had something special. She is already certain of the path she longs to follow, and dedicates herself to daily commitments around dancing, acrobatics, swimming, and acting.

This includes completion of any assignments or schoolwork she may be missing out on while on set - Campbell doesn't like to miss out on anything.

Campbell has already sampled victory as the recipient of several top honors related to dance, and insisted to her mother that when they announced her dance team's win over the loudspeaker at a recent competition, she heard the words, "And the Emmy goes to..."
