Daan Koppelman
Head of Lending MidCorp
at ING Bank

While preparing a presentation for a large group, I consulted Deniz for tips and tricks as I knew that is his interest. Rather than giving tips and tricks, Deniz challenged me on my key message, the credibility of my message and authenticity and sparkle in my presentation. I really appreciated the way Deniz coached and helped me improving my performance with a good eye for detail!
