Having been invited by the end of the course to teach at FMDUL, maintained the desire for advanced training. In 2001, following yet another invitation, he studied and specialized in scientific research at the University of Washington in Seattle in 2001.
Later on, in 2002, started a post-graduation with specialization ( lasting two years) in Implant Dentistry at New York University.

Diogo Líbano Monteiro is a doctor available for medicacl technique and research, but is primarily a physician available for patient. Therefore, parallel to the relationship with academia, he developed and invested in its clinical aspect. He began working in the Dental Clinic D. João V in Lisbon at the end of the course in 2000. In 2004, returning from NYU, he became a partner and medical director. At the same time corrdinated the implant treatments at Hospital CUF Infante Santo, at the time the biggest private hospital in Portugal.
Living in the Estoril area for several years and with the goal of bringing oral healthcare closer to home, he decided to create a center in this region. Many of his patients also living in the area apprecciated the increase in convenience and comfort. Although the Lisbon clinic is in a central location (near Largo do Rato) and with great accessibility, having this Estoril clinic allowed an even more exclusive and personal approach.
