Meet our team

I’m Diane Osgood, Ph.D. I’ll work side by side with you to drive positive change and prepare your company to thrive in the new Age of Sustainability.
I help companies and social enterprises build profits with purpose. It’s more than my work, it’s my passion.
As a sustainability strategist and innovator, I create value for your company by embedding brand purpose and sustainability into operations, creating new products and services, and connecting companies with communities.
My specialties include: sustainability strategy, defining and embedding purpose into company objectives and operations, climate change action, carbon foot-printing and emissions reduction strategies, sustainable finance, produce and service innovation, social-enterprise, eco-efficiency, impact assessment and reporting, stakeholder engagement, diversity and inclusion, employee engagement and supply chain codes of conduct.
While working with Virgin Management and Virgin companies, I learned how important it is to embed purpose into every aspect of your business, design your business with customers at the heart of every decision, and truly take care of your people so they take great care of customers.
I’ve helped clients such as DuPont, Monsanto, P&G, Aventis Pharma and many social enterprises become more successful.
I served as a senior advisor to President Clinton for the Clinton Global Initiative and on the Vatican Arts and Technology Council. As Vice President for Sustainability Strategy at BSR, I co-led the non-profit’s transformation to grow revenue 28% over 3 years by diversifying funding, expanding in new geographies, and incentive global collaboration.
