How To Lead Like a Marine Colonel

Marine Colonel Ed Sullivan knows leadership isn’t about barking orders — it’s about trust, clarity, and keeping your cool when things get tough. His approach applies far beyond the military and offers practical lessons for anyone in leadership today.

Key Takeaways

  • Know Your Organization's Pulse: As a Chief of Staff, your role is to understand the nuances across different teams and be a critical connector.

  • Challenge the Status Quo: Just because "we've always done it this way" doesn't mean it's the best approach.

  • Speak the hard truths: Leaders need honesty, even when it’s uncomfortable.

Notable Quotes 

  1. "You've got to have self-confidence. You've got to want to be held to a higher standard."

  2. "If you don't love the people that you're leading and working with, we're not the service for them."

  3. "Success isn't about who's staying late - that's a sign of inefficiency."

Real-World Application

  • Use data to drive decisions

    Example: Don’t just react to complaints. Analyze usage data, service gaps, or customer feedback to guide solutions.

  • Communicate with steady confidence

    Example: In times of stress, take a moment to assess before responding. Your calm tone will shape how the team reacts.

  • Adapt how you brief your principal.

    Example: Some leaders love spreadsheets; others need visuals. Learn how your principal digests information and adjust your approach.

Leadership isn't about a rank or title. It's about creating an environment where people can grow, solve problems, and feel valued. Whether you’re managing a company or leading a team of 11,000 Marines, these principles remain the same.
