He received his dental degree from the Faculty of Dentistry at Semmelweis University, Budapest (Hungary). Upon his graduation, Maciej pursued a Doctor of Medical Sciences title, obtained after pass with honors for his dissertation defense on composite inlays-onlays in the restoration of endodontically treated teeth. Maciej has been a long-time researcher and lecturer, working with dental students at the Department of Propedeutics of Conservative Dentistry of CMUJ, Krakow. During his International Association of Dental Research scholarship, he conducted research work on adhesive bridges (FDPs) as well as the restoration of endodontically treated teeth at the universities of Leeds and Manchester. He has been a visiting professor at the University of Chieti (Italy), and visiting lecturer the UIC University (Barcelona). In 2021 he became a mentor at the prestigious Kois Center in Seattle. In 1999 Maciej established his private practice “Dentist” in Krakow and maintains it with his energetic attitude and everlasting passion.
