John Denner Music

John Denner began playing piano at the age of 3 and soon started using his gift at his local church at around the age of 8. He played in the Flint Youth Philharmonic for a while before joining a quartet from Burton, Michigan called the Harmonaires. He enjoyed playing with an all-star lineup of musicians in their live rock band for five years. Later, he traveled with The Foresters from Burton, Michigan for two years and enjoyed every single second. But, nothing could eclipse the joy he has ministering with his own family. It is a thrill every time he steps onto a stage with them.
