CINCINNATI, OH — The U.S. Army Corps of Engineers (USACE) Great Lakes and Ohio River Division (LRD) welcomes its new Commander, Colonel Daniel J. Herlihy, during a Change of Command ceremony at the John W. Peck Federal Building in Cincinnati, Ohio.
Herlihy assumes command from Major General Mark C. Quander, who has led the division since 2023. The ceremony was presided over by Lieutenant General William H. Graham Jr., 56th Chief of Engineers and Commanding General of USACE.
“LRD is a world-class engineering organization renowned for its professional workforce, outstanding program delivery, and reliable partnerships,” Graham said. “Under Major General Quander's leadership, the division delivered an impressive array of quality projects on schedule and within budget. As you turn over the reins to Colonel Dan Herlihy, you are leaving the division better than you found it. Well done.”
A Tennessee native and career engineer officer, Herlihy most recently served as Executive Officer to the Commander of U.S. Central Command. His 24-year career includes multiple combat deployments, senior leadership assignments in special operations engineering, and command of the 20th Engineer Brigade. He holds three master’s degrees, is a licensed Professional Engineer, and is certified as a Project Management Professional.
“I am honored to join this exceptional team and to lead the Great Lakes and Ohio River Division in continuing its mission to serve the region, our partners, and the American people,” Herlihy said. “The challenges we face — from infrastructure resilience to navigation and environmental protection — are critical to the nation’s security and prosperity.”
