Clifton Grammar Junior & Senior School was established in 1982 by an acclaimed educationist, Mrs. Rehana Saeed (Late), in the vicinity of the Defence Housing Authority Karachi, with the definite endeavour of providing an effective and resourceful education intended for the youth of the nation. Because of her strong determination, Clifton Grammar Junior & Senior School has always been a part of prestige, and it has always enjoyed the reputation of being among the few prestigious schools in Karachi.
