Mario Simoni was born in Rome on March 30, 1988. He grew up in Viterbo, where he fell in love with tennis, his greatest passion. He soon stopped playing tennis and, when he was 16 years old, he started to teach at CUS Viterbo, working and studying alternately. After finishing high school, he moved to Rome, where he got a degree in Political Science with highest grade, and continued with his FIT instructor activity: attending classes in the morning and training at Circolo San Polo in the afternoon. His experience enriched thanks to Circolo Sportivo Italia, the club where he worked with young professionals aged between 12 and 17; it is the same position he covers now at Rome Tennis Academy. He considers teaching his reason to live and he strongly believes in the necessity to create a special connection with children.
