Since his early twenties, Abbas Katoozian studied at the Kamal-ol-Molk Conservatory under the guidance of Hossein Sheikh and Mahmoud Olya. Throughout his active years, he conducted several solo exhibitions in Iran, America, and France. Just days before his passing, a comprehensive collection spanning fifty years of his artistic endeavors was showcased at the Niavaran Cultural Center. In 1998, a book featuring the collection of Katoozian's paintings was published.
