Born and raised on a farm near Ames, Bert Mackie served in the United States Army Reserves and, as a non-traditional student, earned a degree in Accounting and Finance and later an Honorary Master of Law. At Security National Bank of Enid, his banking career has spanned more than six decades—named president in 1990 and vice chairman of the board in 2006.

An advocate for higher education and a leader in fundraising efforts for student scholarships, he is a founding member of the Oklahoma Foundation for Excellence, past regent for the Oklahoma State Regents for Higher Education, and a trustee for the Enid Higher Education Council. He served on the governing board of the Oklahoma College of Osteopathic Medicine, an advisory board member for the Meinders School of Business at Oklahoma City University, Northwestern Oklahoma State University Foundation Investment Committee, and the Board of Trustees for Northern Oklahoma College Foundation. Believing in service to one’s community, those benefitting from his time and expertise include Hamm Financial Group, ONEOK, Inc., Oklahoma Academy of State Goals, St. Mary’s Regional Medical Center, and the Garfield County Joint Industrial Foundation. On the national level, President Ronald Reagan appointed him to the Board of Governors of the United States Postal Service. His list of awards is lengthy, but one of his most treasured is the naming of the “Bert and Janice Mackie Planetarium” at Northern Oklahoma College.
