David Mayhan

Dave embodies S&C’s balance of strategic and tactical expertise in that he possesses more than 20 years’ experience in both planning and execution. He began his professional career as an officer in the United States Marine Corps, serving in a variety of locations and environments, and retiring from service as a Lieutenant Colonel. Dave enjoyed extensive experience consulting at the executive level to multinational task forces around the world, focusing on both operations management and organizational design. His final assignment was to San Bruno, California, where he served as both the Director of Operations and second in command of a regiment of 4500 personnel dispersed across the US. After two decades in a highly mission-driven career, Dave was determined to continue equally meaningful work in the private sector. He found an answer to that call with Schaffer&Combs, and has been serving purpose-driven organizations ever since.
