    Haley is one of our youngest team members. Currently working as a veterinary assistant, this very special hometown girl is fluent in sign language and pursuing her dream to be a licensed veterinary technician. When she isn't busy helping clients and their pets, she loves to spend time with her son Hunter and hang with her dog, Apollo, and cat, Willow. Haley is always looking to bring the brighter side of life to all who come in contact with her, which is greatly appreciated by both her teammates and clients.
