DES MOINES — Tom Davis is retiring — and this time, it’s for good.

The former Drake coach said Thursday he is stepping down from his job as an assistant to the school’s athletic director. The move comes one month after his son, Keno Davis, left the Bulldogs to become the head coach at Providence.

The 69-year-old Davis was Drake’s coach for four seasons and led the Bulldogs to their first winning season in two decades in 2006-07. He retired from the bench before last season, but stayed on as a special assistant to Sandy Hatfield-Clubb.

‘‘The five years that I’ve been here altogether have been terrific,’’ Davis said. ‘‘I just can’t imagine having more fun than I’ve had in the last five years.’’

Davis, known as ‘‘Dr. Tom’’ after earning his doctorate from the University of Maryland, left coaching in 1999 after Iowa failed to renew his contract.
