Built on Experience

Flying G Excavation is led by Bubba Ammann and Mark Greco, who bring more than two decades of hands-on experience working with Texas land, ranch properties, and outdoor construction projects. 
Their background in ranch maintenance and land development shaped the company’s practical approach to excavation: understand the land, build with purpose, and do the job right the first time.
