The often-dangerous leap into international work was a work in progress for Langan Engineering & Environmental Services for more than a decade. And for George Leventis, it was a labor of love. Langan International serves as the lender’s technical advisor on the Elefsina-Korinthos-Patrea-Tsakona Motorway in Greece.
