Dr Debora R. Vilaboa graduated from the Complutense University Faculty of Medicine and Surgery in Madrid. The same year, she was accepted at the Seville School of Dentistry, where she obtained her dental degree. Later on she chose to attend the Advanced Pediactric Dentistry Program at the University of Southern California in Los Angeles.
