Pietro was born in 1975 in Milan, Italy, where he later trained as a civil engineer. His passion for Africa inspired him to first experience the continent as a volunteer in the Tarangire Lion Project, a research project on the lion population in Tarangire National Park in northern Tanzania. He studied to become a professional guide in South Africa's Kruger National Park, where he received qualifications for ARH (Advanced Rifle Handling) and, later, Level 3 certification from the Field Guide Association of Southern Africa (FGASA), the most important accrediting association for safari guides in Africa. He also received the Trails Guide qualification from FGASA for walking safaris in areas with potentially dangerous game, obtained at Beho Beho, Selous Game Reserve in Tanzania.

Pietro has worked as a guide and camp manager in southern Tanzania in two of the wildest and most untouched areas on the African continent—Ruaha National Park and Selous Game Reserve. He has gained invaluable experience over the years while becoming intimately acquainted with these regions by working at three different camps. Pietro has also been a walking guide in Klaserie and Timbavati game reserves in South Africa. An avid and accomplished photographer, he has had many of his photographs published in East Africa guidebooks. Pietro currently works as a consultant, guide and trainer in various locations throughout Africa. He speaks Italian, English and Kiswahili.
