What our customers say

"Working with Gerco is a roller coaster experience with world-class business results as the end-station. Gerco has been working for my business since January 2010, and keeps impressing me with his deliberate and passionate style of translating embryonic ideas into compelling business propositions. Not only is he a self-starting professional that quickly grasps the potential growth elements, he also rallies colleagues, customers and stake-holders in the industry value chain around his ideas, educating himself and others in a highly engaging way. The Diamond Insight way of working has resulted in two powerful outcomes sofar : a Europe-wide toll manufacturing agreement to develop the secondary operations market for exhaust mufflers and a strategic business proposition to access a new $700MM market in an area where Owens Corning had not yet been active ."
Peter Adriaansen - General Manager Owens Corning's Acoustic & Thermal Solutions Business

"Gerco is a highly talented marketing and sales professional with a passion for winning. He brings a seasoned and focused intensity to his work with a high attention to detail, a creative approach to problem solving with an eye on strategic objectives and financial results. He is able to work alone very effectively or within a group as he strives to educate himself and others, while he builds consensus around ideas that make sense and drives towards results. Gerco was able to put in place the groundwork for establishing a metal and glass panel fabrication business to produce parts for the RV/caravan industry in Europe in less than two years: a very good outcome in a short period of time."
Chuck Jerasa - General Manager, Fabwel Inc., USA, hired Gerco as a Business Consultant

I am now equipped to turn problems into opportunities and I am far more effective in achieving the results that I want "
