 Professor Hovhannes Pilikian states in "Exceptional Music Concerts" under the heading of 'The Maestro and his First Class "Students"' that four of Portugheis' piano "students" presented in a concert –Clare Jones, Katalin Csillagh, Jovanni de Pedro, Blagoy Filipov– are " already technically speaking masters of the keyboard – each a concert pianist of virtuosic proportions".Pilikian comments that "any one of them alone would bring honor to a teacher and their national cultures".Ksenija Ristic, Katalin Csillagh, Gloria Campaner, and Spanish pianist Daniel Bland list Portugheis as one of their teachers.
