Grant Rolston was born and raised on a commercial cattle ranch in the interior of British Columbia, Canada. He was active in 4H both as a member and a leader for several years.

After leaving home, Rolston worked with purebred cattle starting in the late 70's and has shown cattle at several major livestock shows. Up until the spring of 2002, Rolston maintained his own small herd of purebred cattle.

The photography interest started as a hobby when Rolston was a teenager. Formal training as a photographer was taken while with the Edmonton Police Department. Rolston later attended the Browarny School of Livestock Photography and accepted the opportunity to work with Browarny Photographics for two years. The experiences gained has enabled Rolston to pursue livestock photography independently.
