In 2 years we worked together Denis took our business from just as - to the industry leader, all on the back of his vision. I have seen Denis lead and be part of great effective teams, he’s great at communicating and uses his network to get stuff done... It’s very rare to meet someone who impresses you every time you meet them, and he does this without trying - it’s just Denis. He earns my highest recommendation.

Denis was key in developing and making successful our on line selling tool at Rexel Energy Solutions in Northern Europe, not just because he fully understands what needs to be done but also the way he worked with the sales teams to understand and promote it.

Denis is a complete 360 degree professional and I have no hesitation in recommending him.
