In commenting on Mr. El-Hillow’s appointment he stated, “In his roles as both corporate executive and board member Mike has played an instrumental role in both our evolution and growth. His leadership has been a catalyst in Evergreen’s expansion from a small regional technology company into a global manufacturing and customer service organization with facilities and offices in the United States, Europe and Asia. In addition to his financial role, Mike assumed significant operational responsibilities over the last year. His direct leadership is driving our Devens facility to exceed all of its operating goals as well as enabling Evergreen to move decisively with its expansion in China.”
