Leah Sauerwein, Student Coordinator

I was born and raised in St. Louis, Missouri, but moved to Colorado in 2013 to earn degrees in Neuroscience and Psychology from the University of Colorado Boulder. Currently, I am a Doctor of Veterinary Medicine candidate pursuing my diverse interests in animal health, clinical medicine, environmental advocacy, and public policy. This brought me to the One Health Institute, where I was grateful to spend a pandemic summer collaborating on a continuing education course regarding sustainability initiatives in veterinary practice. Through this role, I am excited to participate in community outreach and education and serve as an advocate for advancing the concepts of One Health and One Medicine. Outside of CSU, my hobbies include hiking with my energetic German Shepherd Dog, downhill skiing, exploring local breweries, and traveling.
