CLIENT EXPERIENCE

Others often describe Ms. Ayres’ work as bridge building: making essential connections between companies and regulators, executive teams and investors, corporate leaders and stakeholders, competitors and allies, tradition and innovation. 

“I worked with Merribel when I was CEO at Enel North America. She and her team were strategic in making all the right connections for the company in Washington (and beyond). They supported presence and expansion into the US as a highly credible and respected company with investors, policymakers, business partners and stakeholders and the achievement of results in record time and with impressive impact!”

“Merribel’s ability to quickly diagnose the central issues decision-makers must grapple with and to see through the thicket competing interests is indispensable when trying to move forward groundbreaking ideas.”
