As COO for Sustainability Services, I am responsible for leading the teams that deliver sustainability solutions to our clients around the world.

In what way do you and the teams you lead further ENGIE Impact’s mission to accelerate sustainable transformation?

Every day, the economic and environmental benefits of sustainable operations go unrealized because organizations simply don’t know where to start. Our teams work with clients to help them understand the value of implementing sustainable strategies, projects and business processes that reduce their environmental and social impact while realizing economic growth.

What does success at ENGIE Impact look like?

Success at ENGIE Impact is expanding our global footprint of clients and increasing the number of organizations successful accomplishing their sustainability goals and roadmap action items.

How did your background prepare you for this role at ENGIE Impact?

Through my 28-year career in the energy and sustainability marketplace I have helped hundreds of companies improve their business processes efficiencies while improving their economic results as well as reducing their environmental impact.

  • As COO at ENGIE Insight I have been leading our global operations, ensuring the delivery of integrated energy and sustainability solutions to our clients. Before that, as Vice President, Global Operations Strategy I aligned operating groups in international locations, ensuring clients achieved insight into their global energy and sustainability footprint.
  • As Vice President, Sales and Client Management and then Vice President Operations, Expense and Data Management at Ecova, I led teams in the pursuit of process efficiencies and the delivery of market-leading results.
  • At The Loyalton Group (which was acquired by Ecova in 2011) I was co-founder and chief operating officer, leveraging the newly emerging deregulated energy market to introduce both supply side and demand side energy management services to our clients.

What do you like to do when you’re not in the office?

I enjoy spending time outdoors and with my family.
