格蘭英語於1980年創立於現敦南總校大樓，為台灣學習英語風氣之啟蒙。除了成人及兒童英文課程，更因為優質教學口碑，受許多知名企業青睞，而成立了外事教學部 ( GRAM English Services) 及展業部、加盟部。
GRAM was established in 1980, beginning with its Dun-Nan school in downtown Taipei. Today, as one of the leading language learning institutes in Taiwan, GRAM currently operates more than 200 school locations, with over 1000 employees and tens of thousands of students, including children from age 5 to top executives in a variety of business corporations. For the past 33 years, GRAM has also operated its own Franchise Department, GRAM Children's Service Department, and GRAM English Services – popular with many domestic business corporations – to ensure the quality of our English learning programs.
Because GRAM's Modern Children's Program has been highly popular among parents, we have also established the Piper American School, providing a whole-day English program for children aged 5 and 6. Additionally, GRAM has cooperated with ICRT, the island's only English radio station, to publish GRAM Digestand to provide an overall more diverse learning environment for its students. Drawing upon its many years of experience, its excellent teachers and its diligent students, GRAM is making its best effort to conduct and promote the government's “English for All” policy. As GRAM approaches its 34th year in Taiwan, we are proud of our quality English programs which have helped many of the island's students become excellent English-speakers.
