Peter F Gallagher

Peter F. Gallagher is a leadership advisory, education, and publishing brand founded around Saeculum Leadership®, a generational approach that frames leadership as a civic, moral, and long-term responsibility. Gallagher advises boards, executives, governments, and public institutions on stewardship, sound judgement, institutional resilience, change, and leadership across generations. His work asks what future generations will inherit from today’s decisions and how leaders can strengthen organisations for those who follow.

The brand offers keynote speaking on Saeculum Leadership®, generational stewardship, institutional resilience, and long-arc transformation. Its advisory services support boards, CEOs, and executive teams with strategic guidance on leadership, change, and institutional stewardship. Executive education and online training, including global certification and practitioner learning, help organisations build capability to navigate complexity and sustain transformation. The Saeculum Leadership® Body of Knowledge (SLBoK) presents the concepts, principles, models, and glossary behind this approach. Gallagher is also the author of 22 books covering leadership, organisational development, change management, and gamification, including the Saeculum Leadership® Canon and related bodies of work.
