Justin Constantine’s background in the Marine Corps and his personal experience as a leader in the private and nonprofit sectors have prepared him to assist the rest of us who lead people on a daily basis.  I have seen Justin’s strong influence in the veteran community, and as he says, taking care of your people has to be your number one priority.  I couldn’t agree more.  For anyone who wants to become a more thoughtful and effective leader – I urge you to read and explore the many lessons contained in Justin’s excellent book, “My Battlefield, Your Office.”

I have known Justin for the better part of a decade, and we both share significant injuries from our time in Iraq.  Justin exemplifies that we hope for all of our wounded warriors: perseverance, grit and success.  As a leader in the veteran community, it is only natural that his leadership lessons are so clear and well-stated.  We can all learn from Justin, and certainly any manager or supervisor will benefit from this impactful book.

America holds our veteran in incredibly high measure, and Justin is a perfect example of why we do so.  After leading teams with the Marine Corps, the US Chamber of Commerce, and in the nonprofit sector, Justin generously shares with us what it takes to successfully lead people. My Battlefield, Your Office is a must-read book for any manager or supervisor.

Justin inspires me – not by the magnitude of his injuries sustained in Iraq, but by the depth of his passion to use that experience to motivate himself and others.  A superb leader and valued mentor, his message offers all of us valuable lessons in leadership, tenacity, and living a life of purpose.
