  • Bobbie
    - Lead CSR

    Bobbie's career in vet medicine actually began in 1998 when she began working at a veterinary surgery specialist. Her passion for animals ignited during those days and the rest is history! 

    Bobbie joined us in 2020 and we couldn't imagine the hospital without her caring disposition. She has an affinity for the tiny dogs especially and her own critter crew includes two chihuahuas and two kitties.

  • Autumn
    - Veterinary Technician

    Autumn joined the team in 2021 after moving to Florida from Texas. She's always had a passion for animals and caring for them. Her love for horses is what started her interest in the medical side of animal care. 

    She has grown so much in the time that she's been with us. For now, she's working with cats and dogs but one day hopes to work with larger animals.

  • Jordyn
    - Veterinary Technician

    Jordyn joined us in 2022 and has learned so much since then! In her free time you can find her reading, tending to her plants, or enjoying a good movie. She enjoys outdoor activities such as hiking or swimming, especially in the summer! 

    Caring for animals has been a passion of hers and being a vet tech is the first step in a life long career of animal wellness.

  • Errol
    - CEO (Cat Excellence Officer)

    Errol is our Kingsley Animal Hospital emotional support cat. He was brought in as a kitten in 2021 after he'd been thrown out of a car window and run over. He required some intense hospitalization for a few weeks but he has blossomed into the best little office supervisor. 

    The car incident left him with some neurological issues and he will never be 'normal' but he is imperfectly perfect to us! You may see him hanging around the hospital, napping in his window seat, or greeting humans and pets alike in the lobby/rooms.
