In 2008,  Mr. Akin Aboaba spearheaded the formation of IGSOSANA with a vision to bring old students of Ibadan Grammar School living in North America together. The  inaugural meeting was held in Pharmacist Kayode Ogunnaike’s house in Maryland in a fairly well-attended meeting where the Ogunnaikes were great hosts.

Later in the same year the 1st Convention/Gala Night was held in Washington, DC. The inaugural President was Prince Sunmade Akin-Olugbade. Among the people who graced the occasion were Late Engineer Seke Somolu and several people who came from many parts of North America. Femi Pearse came from Minnesota, Professor John Ohiorhenuan, Sigismund Sule, Mrs. Nike Akintewe and late Jubel Adenekan came from New York, Mrs. Funke Oluyemi and Mrs. Tayo Thomas came from California, Dr. Omololu Adesioye and Dr. Dapo and Mrs. Bunmi Akinyele came from Canada and brought the Canadian flag with them, Ms. Eniola Ogedengbe, Sunmade Akin-Olugbade, Sammy Odumodu and the Ogunnaikes represented Maryland, Jide Ogugbadero came from Boston and Professor Kiumi Akingbehin came from Michigan. 

The 2nd Convention/Gala Night was held in Atlanta, Georgia, in 2009 and was well-organized with Attorney Yinka Omole literally serving as a one-man army to welcome everyone to Atlanta.  Dr. Gboyega Osinbowale became the President of the association at this convention.

Dr. Osinbowale helped to streamline the operations of the association, by starting a quarterly business meeting and registering the association formally as a nonprofit 501( c ) 3 organization to raise funds and allow donors to benefit from a tax-deductible status. He instituted a structured accounting system (with the assistance of a Finance Committee) that ensured transparency and accountability of the officers and proper keeping of the books and finances. Finally, he identified a project that will be beneficial to Ibadan Grammar School and serve as a perpetual legacy for generations to come. 

Today, all these goals have been accomplished and our legacy of a modern 100 student capacity Physics Laboratory which was first mooted during the 4th Convention in Boston in 2011 started in reality with the laying of the foundation of the Laboratory on Friday, November 02, 2012, with a completion date of August 31, 2015.
