Everett was born in Calgary in 1909 and received a Law degree from the University of Edmonton in 1936.
Everett attended St. Mary's High School and went on to obtain a Bachelor of Law degree at The University of Alberta in Edmonton in 1936. Everett practiced law in Calgary with the Sanford and Costello firm until he joined the Canadian Army in 1941, and served as legal counsel during the war, except while he was stationed at Camp Borden as Captain in the Armoured Corps.
He was eventually transferred to the Judge Advocate Generals’ Department where he remained until the end of the war. Within two weeks of leaving the army, Everett joined Mannix & Co. Ltd as Assistant Secretary and General Counsel. Everett remained with Mannix for the next thirty-five years, where he served as Director, President and Chairman of the Board. He officially retired in 1982.
Everett was the nucleus of a devoted family and husband to Florence for 42 years, and father to Genevieve, Susan, Frances, William and John. His contributions to the corporate world were great, and was his contribution to the Province which was recognized in his appointment as Queen's Counsel, and the value of his experience and ability was demonstrated by his appointment to the Senate of The University of Calgary.
The growth of our Province and our Country have only been possible by depending on the drive, dedication and love of men like Everett Costello.
