WARSAW—MSLGroup Poland CEO Sebastian Hejnowski has been promoted to a newly-created role as CEO of the PR network's operations across Central and Eastern Europe.

Hejnowski, who continues reporting to MSLGroup EMEA president Anders Kempe, is tasked with driving growth and integrating the network’s brands in Romania, Bulgaria and Slovenia, in addition to his existing Poland leadership role.

Hejnowski's promotion comes amid a senior-level reshuffle at MSLGroup, which has seen the appointment of new CEOs at a global (Guillaume Herbette) and US (Ron Guirguis) level.

Hejnowski has been with MSLGroup in Poland since 2004, when he joined Cizewski Public Relations, which sold to the French PR network in 2011.
