International Call Centre Manager

I really enjoyed the small group environment of this workshop. It was interesting to learn about different people’s challenges with vocal communication. This heightened my own awareness about my strengths and weaknesses with speaking and presenting. I also thought it was constructive to receive feedback from my peers.
