Catherine Rowan-Collier wanted to be a veterinarian since childhood, and it has been her honor to care for cats and dogs for the last 24 year in a variety of settings. She has helped pets and their parents in private practice, corporate practice, emergency clinics, shelters/rescues, as a public health veterinarian with the federal government. Her special interest is in One Health, which studies how the health of humans, animals, and the environment intersect and impact each other. By combining her veterinary medicine background with her prior career as an RN, One Health is an ideal way to help pets, people, and the world around us.
