    My ambition has always been to move forward, always continue to develop and improve. I seek new questions where there are none and challenge what it is held as truth. My foremost goal is to inspire firefighters to learn, to make them students of their trade.

    When the will to learn is there, all I have to do is to point them in the right direction, as so many have done for me. The practice of firefighting is a life-long learning endeavor where absolute truths are scarce and logical fallacies fill the gaps in our knowledge. Being a student of firefighting means being open to change. Our new experiences combined with an influx of science helps us to let old beliefs die.
