Mike Budenholzer has been an assistant at San Antonio since 2007.
The Atlanta Hawks named Mike Budenholzer as the team's new head coach on Tuesday.
Budenholzer has spent the last 19 years with the San Antonio Spurs, mostly as an assistant coach under Gregg Popovich.
"We are thrilled to have Mike as the next coach of the Atlanta Hawks. He has incredible basketball acumen and has a keen awareness of the league and what it takes to be successful," General Manager Danny Ferry said.
Budenholzer will replace current coach Larry Drew after the NBA finals.
The Spurs will face the Miami Heat or the Indiana Pacers in the NBA finals that are scheduled to begin next week.
