Keller Group
McKinney Drilling Company was founded in 1937 by the late Jack & Richard McKinney, who helped pioneer and develop the mechanized drilling machine as we know it today.
McKinney Drilling's history was filled with many firsts, innovations, and prestigious projects, which led it to become North America's leading drilled shaft foundation company.
