Matt Travis, CIO

As I considered the opportunity to serve on the board, like many my first reaction was, “Do I really have time for one more commitment?”  Upon closer examination of the mission of Oregon APEM, it became clear that this was something worth committing too.  Understanding energy efficiency is key not only to our environment, but our economy and the success of each individual business or organization.  Helping the industry understand how energy efficiency is good for everyone, is something I’m already committed to.  Serving APEM is just an extension of the commitments I’ve already made and I’m excited for the opportunity to be considered for a board position and continuing these efforts.
