Singing harmony is second nature to Gardiner Sisters. They come from a family of entertainers that loves the universal positive influence of music. Though each has a recognizable solo voice, it is hard to beat the unique blend that comes from Sister's voices. Gardiner Sisters are dual citizens of the United States and Canada and have crossed the continent songwriting, performing and recording a mixture of pop, acappella, and contemporary music.  

Mandi, Allie, and Hailey are currently working hard to take their harmonies to the next level through the SLS program. Their goal is to uplift, inspire, and entertain worldwide audiences and highlight the joy and goodness in the changing world around us.
