Gianmauro is one of the few people in this world on whom I can rely on more than on myself. Nigretti Studio accounting is efficient, prompt, diligent and relentless in striving for result-orientated accounting, consulting and operations management. For the past 5 years I have had the pleasure to work with Gianmauro on a variety of different projects including technology companies and real estate deals. His international experience and orientation gives him a unique perspective and singular insight in successfully overcoming the meandering rivers of bureaucracy.

As previous President of Gates European companies, I had the privilege to count Mr Gianmauro Sherman Nigretti as our lead financial and fiscal assessor for our Italian company.
Gianmauro’s professional attitude and deep knowledge of general business matters as well as financial and tax legislation helped us to operate in Italy in the most efficient and correct manner.
