Allan BushJ. Allan Bush, P.E., President Allan Bush is an established professional in the Kansas City Geotechnical Engineering community. Having been in the industry for over 20 years, he has deep insight for the interworking of Kansas City soil and it’s land heritage. While deeply seeded in the industry today, Allan personally identifies with Alpha-Omega and can’t help but assume there was slight career foreshadowing – first resume, first interview, first job, and first-time business owner. Now functioning as AOG’s President/CEO for over 16 years, in succession of former founder and KU professor, Allan continues to inspire organizational learning and innovation – always looking for opportunity to empower ‘old’ (a.k.a. experience) with ‘new’ (a.k.a. industry) and aspire for better. Whether personal or professional, he embraces vintage and has an eye for perfection. Allan Bush – cigar enthusiast, regarded engineer.

Blake BennettBlake 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 material inspection and mix design. Acclaimed for his investigative role in the rebuild of KCPL Hawthorn Power Plant explosion of 1999, there instating Blake’s nickname ‘Concrete Guru’, AOG’s CEO Allan Bush had first-hand witness to his creative hands-on troubleshooting and knew they were soul scripted – a professional tenure now going on 12 years. Blake’s visionary allure and handcraftsmanship fuels his consultancy appeal, allowing fulfillment of needs customers may not even know they have. Blake, known to be a straight talker, may be visionary but also prefers simple; he desires to exploit resources for simplified delivery versus complicating for hollow value. In summary, Blake is a true team player – in it with you and for you. And that goes for home too where he is fondly referred to as the “World’s Greatest (Grand) Dad” – with a trophy to prove it.

Garic AbendrothGaric Abendroth, P.E. Engineering Department Manager Garic Abendroth was introduced to the construction field early on as an apprentice in a family run construction company. Going on to receive a Civil Engineering degree from Kansas State University brings him cumulative knowledge that intersects soil and structure – the cornerstone of serviceability. Having full-cycle awareness allows Garic to remedy the unexpected and drive collaboration across construction processes. He is not wired to sit-back-and-wait; he brings a practical diversity that delivers quality and confidence even amidst the unpredictability of subsurface terrains. His proactivity and contagious energy is what sets Garic apart and his passions are as diverse as his skill-set – during off-time, you can find him either riding his motorcycle or kicking back to a local KC band.
