Nancy Salisbury, CEO

Nancy Salisbury

Sylvie Guillon, Partner

I’m an optimistic visionary in constant turbo mode. As a leader, communicator and builder for 25 years, my sustainability work has impacted hundreds of organizations. Always ready to listen and learn, I immerse myself in conversations, organizations and communities. I earned a PhD in Organizational Leadership, focusing on social media and technology. I’m a Visiting Professor at St. Edward’s University, teaching CSR and public relations. My first book, Aware: CSR Communication Strategy, is in the peer review phase.

Sustainable living began in my childhood with gardening, composting, recycling, and reduced water and energy usage. I've explored 24 national parks and over 100 state parks, enjoying tent camping, hikes, water activities, and listening to ranger talks. For ten summers I lived off-the-grid in a cabin near the Olympic Mountains.

I launch initiatives with passion, innovation and grit. This trifecta of upbeat energy develops relationships, creates wow-worthy sustainability communication campaigns, and delivers business results to help build a better world, one conversation at a time.

I have a passion to help companies transform their business and implement sustainability strategies to find new opportunities for success. I believe that altogether, we have to collaborate to accelerate climate action and ensure a better future for all.

With 20+ years of professional experience, my career has spanned the banking, software and IT sectors, in France and in the US. I have a broad experience of web, digital marketing and brand. I managed the external communication for CSR initiatives at Dell and defined the digital experience to promote the yearly ESG report.

I am a problem solver and offer global leadership creating sustainability strategies to generate efficiency, cost savings and enhanced performance. I know how to bring people together and drive the success of cross-functional complex projects.

I have a Master in Marketing Strategy and recently graduated from the ClimateBase fellowship program as well as the OnePointFive Academy in Sustainability consulting.

I am French, I have been living in Texas for more than 10 years and I am happy to guide your sustainability efforts in the US or in France!
