Major General (Retired) Mark O’Neil

Mark O'Neil

Major General (Retired) Mark O’Neil started the O’Neil Network during his transition from a distinguished 33-year career in the U.S. Army. Combat-proven and decorated, Mark is continuing his lifelong work through the O’Neil Network – assessing potential, selecting leaders, and helping people and private-sector organizations develop and improve through leadership lessons that can be applied to today’s business environment.

Mark has a demonstrated track record of adding value – connecting passion with purpose, developing teams, inspiring audiences, and building enduring relationships. He assessed, selected, trained and led the most elite special operations organization in the world, solving our nation’s most complex and dangerous problems. Comfortable in crisis action planning in competitive, dynamic, and high-risk environments, Mark energizes leaders by inspiring them to act with disciplined initiative. Mark consistently establishes a culture where teams strive to be proactive, focus on priorities more efficiently, and optimize problem-solving skills.

Mark’s extensive leadership experience with conventional and special operations units has made him an expert at hands-on crisis management. During 16 years with the U.S. Army Special Operations Command, Mark became adept at working in changing and stressful environments. He is an expert at managing ambiguity in decision making, with a deep understanding of what it takes to lead in the face of uncertainty.

He has consistently emphasized that relationships matter and has built enduring international connections throughout his career. As the Deputy Commanding General - Operations for 10th Mountain Division, Mark leveraged strategic planning, leader interaction, and blending of ideas to create and sustain partnerships across conventional, interagency and special operations portfolios. He simplified the complex to focus on the mission – achieving unified goals with measurable outcomes while facilitating a streamlined approach to organizational competency.

Through Mark’s vision, mission and priorities as two-star commander, combat formations across 11,000 personnel in three separate Alaskan locations increased lethality, readiness, and deployability status for worldwide contingencies. The result: all combined arms maneuver formations within his command met or exceeded standards.

Mark and his wife Wendy are the proud parents of Taylor O’Neil (30) and Staff Sergeant Riley O’Neil (26), currently serving as an Airborne Ranger in 1st Ranger Battalion, 75th Ranger Regiment.
