APEGA has existed for more than 100 years, and for every year of its existence, there has been a president of Council to uphold the pillars that APEGA stands for: integrity, accountability, innovation, and service. Through the decades of change and growth, the men and women listed below led APEGA’s Council.

They have worked across the globe, from Mississippi to Venezuela, but all settled their talents here in Alberta. Each came from different walks of life, from serving in the Second World War, to teaching aeronautics, to instigating first-time overseas ventures. This incredible group of outstanding people made their mark on the world and helped make APEGA what it is today.
