Allan Bush  Allan Bush, P.E.
Direct Dial: 913-717-4081 

With over 29 years of geotechnical engineering experience, Allan Bush has deep insight into the interworkings of soil and land in the Kansas City area. Alpha-Omega has been Allan’s home from the beginning – his first resume out of college, his first interview, first job, and after proving his capabilities, he became the president and a first-time business owner over 25 years ago. In succession of the former founder and KU professor, Allan continues to inspire organizational learning and innovation – always looking for the opportunity to empower the new generation of geotechnical engineers with the older generation’s experience. An avid cigar enthusiast, Allan embraces vintage, has an eye for perfection, and cares deeply about the future of Kansas City.

Blake Bennett Blake Bennett 
General Manager / Business Development 
Direct Dial: 913-717-4080 

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 handcraftsmanship fuel 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 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. And that goes for home too, where Blake is fondly referred to as the “World’s Greatest (Grand) Dad” and has a trophy to prove it!

Garic AbendrothGaric Abendroth, P.E. 
Engineering Department Manager 
Direct Dial: 913-717-4082 

Garic Abendroth was introduced to the construction field early on as an apprentice in a family run construction company. His Civil Engineering degree from Kansas State University brings him the 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 are 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 listening to a local KC band.
