Dr. Mario Filippo Caliò

Private investigator Dr. Mario Filippo Caliò started his career in the investigative sector in the mid-1950s when, to support his studies, he sought work at a Milanese investigative agency. It was there that he discovered his passion for the profession of private investigator, a passion he later described in his book "Investigators at Any Cost" (Calderini Editore - Bologna, 1989).


This love for his work prevented him from completing his studies in Psychology, which were set aside in favour of urgent professional commitments at Globus Investigazioni in Milan, where he served until the late 1950s. He later graduated in “Criminology” in 1974-75 from the prestigious Complutense University of Madrid, the first degree course in Criminology for authorised private investigators in Europe. Years later, while working on locating missing persons, especially minors with drug problems, he pursued further studies in psychology and graduated as a Community Director from the Ferrini State School in Verbania, achieving top marks.

In 1998, he was appointed as a "Lecturer in Applied Psychology," a subject he explored alongside Criminology at the University of L'Aquila from 2000-2004, where he participated in the first degree course in Investigative Sciences in Italy. His studies culminated in a US Degree as "Doctor of Science in Sociology and Criminology" in 2006.


He continues to practice as director of the Novara office, his adopted city where he established his beloved Detego | Europol investigative agency in 1962, a prestigious Private Investigative Organisation operating nationally and worldwide.


Finally, Dr. Caliò is proud to be one of the first private investigators in Novara and Italy to address the issue of stalking (Stalking & Stalkers, – Liberistampautori SaS, – Novara, 2007), a subject he dedicates himself to daily as a consultant for criminal investigations under Articles 38, 222 of Legislative Decree 271/1989, working in Novara and throughout the country within the Detego | Europol Investigative Organisation.
