Erik Larson oversees the achievement of all strategic and operational objectives. Erik has overseen the development and growth of the ECM portfolio into five distinct energy efficiency companies, each independent yet able to leverage sales platforms, auditing resources, project management, measurement & verification, with uniform back office support.

He also played a significant role in the resurrection of the Sheeting Equipment product line which grew from less than $1M back to over $25M during his last role at MWU. Erik’s leadership in lean manufacturing has been driven into the ECM delivery platform and continues to focus on driving unnecessary costs out of the delivery of efficiency projects.
