Brian Crimmins

Global Managing Partner, ONE HUNDRED
CEO, Changing Our World

Brian Crimmins is a global leader in corporate purpose, the creator of ONE HUNDRED—the world’s first coalition of marketing agencies united for sustainable change, a popular public speaker on fundraising and philanthropy, and Chief Executive Officer of Changing Our World, a leading philanthropy and management consulting firm whose team of impact consultants works toward transformative change on the global stage.

As Global Managing Partner of ONE HUNDRED, Brian works with our parent company, Omnicom, and our sister agencies to bring passionate leadership and advocacy to each client engagement. He ensures we surround our partners with integrated teams – culled from across disciplines – with unmatched depth of knowledge and experience in the cause area(s) that matter most to our corporate, foundation and nonprofit partners.

Brian ensures his teams live up to ONE HUNDRED’s mission — sparking change and creating meaningful global impact through the power of communications and philanthropy. With over 20 years’ experience, Brian has helped organizations and corporations turn philanthropic ideas into actionable purpose, driving tangible results with policies, practices and platforms that bring about positive change.

Most recently, in response to the uncertainty in the purpose and nonprofit spaces brought on by the COVID-19 pandemic, Brian launched and is host of the popular virtual conference series, Forging Forward, which hosts global leaders in areas such as corporate social responsibility, philanthropy, healthcare and economics for frank conversations around the impact of the pandemic and how the sector might respond. Across his conversations, Brian encourages a focus not just on what we can be doing organizationally, but on how leaders might organize their inner and personal lives to expand the edges of their own potential.

Brian also serves as Omnicom’s de facto purpose expert, where he has served as a key internal advisor on Omnicom’s commitment to the SDGs through its role in Common Ground. His expertise is tapped in service to some of the world’s largest and most influential corporations as they define their core reason for being and translate theory into action. Brian also served as the leader of Omnicom’s recent community engagement analysis, so that it might better understand the community impact of more than 200 agencies across its network.

Brian holds a Bachelor of Science from St. John’s University and an MBA in Marketing Management from St. John’s Tobin School of Business. He is a graduate of the Omnicom Advanced Management Program, a partnership between Harvard Business School and Babson College. Brian lives on Long Island with his wife and their four children.
