    Veterinary Administrative Assistant

    Inspired by their devotion, Daisy began volunteering at animal rescues. She particularly enjoyed working with cats. At the rescues, she would socialize cats and help find them their perfect forever home. She has her own cat named Moosh Moosh that she adopted at 6 months old. In her free time, Daisy enjoys long walks, to travel, and to shop. In the near future she wishes to go back to school and learn more about animal behavior.
