The Ibadan Grammar School Old Students Association is a thriving organization of thousands of old students living and working around the world. 
A worldwide network of chapters and affiliates of the association extends across major cities in Nigeria, Canada, the U.S., UK and overseas. These groups, 
run by alumni volunteers, help organize events, programs for the school and other great opportunities to keep IGS old students in touch with the school and
each other. Get involved with your local chapter or class set and start reconnecting! 
The President of the IGSOSA National Body is Venerable Kolawole Jaiyeoba
