Following his active career, Pešić studied sports marketing and communication at the University of Venice. In 2007, he became self-employed as a consultant at the company Lumani 10.7 GmbH.[1] In 2008, he successfully completed his studies as a sports manager at IST Düsseldorf, which he had begun during his career as a player.[2]
For the 2011–12 season, Pešić became the new sports director of the basketball division of the FC Bayern Munich.[3] On 11 January 2013, he took over the position of general manager at the Bayern Munich.[4]
On 29 March 2018, Bayern Munich sacked head coach Aleksandar Đorđević after the elimination in the semifinal of EuroCup.[5] During Đorđević coaching tenure, Bayern Munich held first position in the 2017–18 Basketball Bundesliga with 23–2 score before got sacked.[5] Few days after the dismissal, Đorđević qualified it as an "insult for common sense", especially since the 2017–18 season was one of the most successful in team's history.[6] Đorđević also added that there was apparently a disagreement between team's management (in particular Pešić) and his coaching staff, as Đorđević didn't allow bigger involvement of team's management in coaching decisions.[6]
