BLAKE BENNETT, GENERAL MANAGER
Blake Bennett started his career in concrete sales back in 1989. With an inquisitive mind and first-rate workmanship, he quickly became the industry go-to for all materials inspections and mix designs. After his investigative role in the rebuild of the KCPL Hawthorn Power Plant after the explosion of 1999, Blake adopted the nickname ‘Concrete Guru.’ AOG’s CEO Allan Bush witnessed his creative, hands-on troubleshooting skills and knew it was meant to be – a professional tenure now going on 23 years.

Blake’s visionary allure and hand craftsmanship fuel his consultancy appeal, allowing the fulfillment of needs customers may not even know they have. Blake, known to be a straight talker, can be visionary but prefers things simple and desires to exploit resources for simplified delivery versus complicating for hollow value. Blake is a true team player – in every project with you and for you.
