My name is Grzegorz. I live in Rzeszów - together with my family (wife and 2 kids). I like sport (not only watching sport events in TV!), fast cars (who does not like them), spending time with my family (every minute with this trio is precious).

I joined Deloitte 5 years ago and one of my goal was to set up and lead new Deloitte office in Rzeszów in 2011 (Audit and Tax advisory services). That was very exciting and challenging task, I managed to build good team that likes to spend time together not only at work but also during free time (going to pub, sport events, bowling together). After 5 interesting years full of challenges, next challenge comes – Audit Delivery Center (ADC) located in Rzeszów – I am Country Champion for Poland and member of Deloitte Team that is working on scope and framework of ADC in Rzeszów. I look forward to meeting you and I hope you will become a part of this upcoming experience ! All the Best and see you soon !!!
