"Through my academic journey, I saw my passion for aviation come into clear view. I saw I could be successful at work through the Purdue Co-Op program, and got key encouragement from several professors at just the right times. These professors helped me see my potential for achieving goals through hard work and tenacity. They made it clear that hard work and grit can outpace book smarts just about every time.”
