The Mahaffey legacy in the deep foundation industry began in the 1920’s when J.R. Mahaffey established J.R. Mahaffey and Sons. Following in his father’s footsteps, Don subsequently opened Don H. Mahaffey Drilling Company in 1946. Now in the hands of the fourth generation, Mahaffey remains deeply invested in the foundation drilling industry and steadfastly committed to improving its best practices and investing in quality equipment and personnel.
