  • Jen Weston

    I was asked to write a biography about myself. I really dread this task, and my first draft was super stiff and boring. And I'm anything but. So here I got onto my second attempt.
    I grew up in the small town of Newport News, Virginia. I've wanted to work with animals my entire life. In January of 2000, O approached my neighborhood veterinarian and I asked if I could volunteer. I haven't looked back yet. I love all animals, but I have a special place in my heart for cats, and anything neonatal/pediatric. I have a passion for rescue and wildlife, and I've been known to pluck a family of raccoons out of a window well, and nurse baby squirrels and birds back to health. I also love Emergency Medicine and Dentistry.
