He received the orthopedic surgery and Traumatology Diploma from the university of Balamand in June 2008. In October 2008 he moved to Brussels Belgium, where he completed 2 years of fellowship in the Université Libre de Bruxelles (Hopitaux Iris Sud). During these 2 years he perfected his skills in Traumatology, Hip and knee replacement surgery, arthroscopy , as well as sports medicine and degenerative Spine surgery. Leaving Brussels in October 2010 proved to be difficult after having grown a taste for its chocolate, but it was completely worth it to pursue further specialization in Spine Surgery which he holds dear.
