The Gyan Devi Group of Schools is run by The Colonel’s Education Society which was founded in the year 1983 by Late Lt. Col. Kunwar Jaswant Singh. The founding father of our school, he was a visionary par excellence. He had great dreams for the school, which we shall always endeavour to fulfil. The foundation stone of Gyan Devi Montessori School Sector-9 was laid on August 26, 2002 by Late Smt. Gyana Devi w/o Late Maj. J N S Yadava. Her blessings and good wishes have been instrumental in the overall development of the school, and will continue to be a source of inspiration in the years.
