Dr Guillermo Doria holds a PhD and a degree in Dentistry from the Universitat Internacional de Catalunya (UIC), along with a Master's in Endodontics and an Official Master's in Dental and Biomedical Research from the same university.

His clinical work focuses on root canal treatment, retreatment and apical microsurgery, always working under magnification with a microscope and loupes for maximum precision. He is one of the few specialists in Barcelona dedicated to this type of microsurgery, which allows him to save teeth that other professionals consider lost.
