Leadership Begins and Ends With People

With ideals forged underwater and proven in business, Submarine Close reveals the powerful human connection between relationships and mission-critical success.

Relationships are not ancillary. They are the core strategic and tactical tools of organizational success.

Submarine Close provides more than a leadership philosophy; it provides a way of life. It speaks to what we need as humans: to be seen, supported, and empowered to succeed together.

Captain John McGunnigle and John Ranelli are both veterans of the US Navy’s Submarine Force and accomplished leaders in private business. Together, they share the stories and principles that make Submarine Close an unmatched framework for leadership, teamwork, and results.
