GLS Mission,
Vision & Values


Our mission is to improve communications through the accuracy of translation products and timely interpretation services. We strive to increase speaking, reading and writing proficiency levels of foreign languages and English as a Second Language (ESL) through quality instructional services—from beginner skills through fluency of the language. Our language instructors hold degrees, and many are certified by the Foreign Service Institute (FSI) or the Defense Language Institute (DLI). Our instructors further apply a student-centered approach to teaching languages and tailor materials to the student’s needs.


Our vision is to be the best language service provider in Fairfax, VA, which is located in the heart of the Washington DC region. We built and maintain our reputation on the careful selection of highly educated and experienced linguists. The solutions and services that GLS delivers will, in turn, provide value to our clients, employees and communities that we serve.


GLS’ values are caring for our employees and achieving 100% customer satisfaction. Refer to our specific values below:
