Phillip Calvin "Dr. Phil" Ehart (born February 4, 1951)[1] is the drummer in the progressive rock band Kansas.

Though his songwriting contributions to the group were few, he co-wrote two of their biggest hits, "Point of Know Return" and "Play the Game Tonight".

Like many American musicians in the early 1970s, Ehart wanted to more closely study and play the British style of popular music, so he moved to England.

He did not find the atmosphere welcoming, as the musicians there were happier to learn the country and rhythm and blues styles that Ehart brought with him, so he quickly returned to America.

Ehart endorses Yamaha drums,[6] Evans drumheads, Promark drumsticks, and is a longtime user of Zildjian cymbals.
