Dr. Nemeth has led a very geographically varied professional life starting training in the US, completing it in Europe. Subsequently, in 2001 he set up shop at the McGill University Health Center's Montreal General Hospital and Montreal Children's Hospital as an attending emergency medicine physician and has been there since. 

He was the department director at the Montreal General Hospital for 8 of those years. He also took part in a "quasi-sabbatical" one year stop in Toronto working at 5 different hospitals (academic/community) in the capacity of emergency medicine physician and trauma team leader. His extensive international lecturing dossier and numerous McGill University teaching awards attest to his passion for teaching.
