Dr. Marco Bolognesi, an economist, is a renowned expert on international investment and taxation. He has built two major financial institutions working with some of the wealthiest people in Italy and internationally. Five years ago, he was the first to spot the genius of SigmaPlus. He is connected to many financial institutions at the highest level; it was therefore a short step for them to explore this new investment service for themselves. SigmaPlus is now working with several substantial institutions in Italy, including his own. Marco has worked with Harry Holt for more than twenty years; they have a strong bond and trust in each other.
