For more than 30 years, InterPrep has been a strong voice in world language education both in the United States and abroad. The leadership of its principal, Greg Duncan, has been felt by hundreds of individual schools and school districts, independent schools, higher education institutions, and international schools in his work as a consultant, a collaborator, and a mobilizer.  His many long-term consultancies have helped to cultivate cutting-edge world language programs around the globe which have become beacons for others to learn from and model themselves after.
