Student and Alumni Spotlight

White Coat Profile: Kathleen LeFiles

A superhero and coffee enthusiast, Kathleen LeFiles is a ‘Wildcat Wonder.’ She was raised in Tucson, AZ, and attended the University of Arizona as a physiology major for undergrad. Even prior to that, though, she had discovered an interest in medicine. It was during her freshman year of high school in biology class, as she was learning about the cardiovascular system. She was absolutely fascinated by the heart’s design and function. That interest fueled her to learn more. And with the unwavering support of her family and friends, she was able to follow that desire to pursue her education all the way to medical school.
