Meet Our Staff

  • Sheila Mathwig
    Certified Veterinary Technician

    Sheila Mathwig has lived in the Lake Mills area her entire life.  In fact, she grew up on the family dairy farm that is still operating today.  After graduating from MATC in Madison and becoming a Certified Veterinary Technician in 1990, she worked in production medicine for two years.  She is happy to have worked for Lake Mills Veterinary Clinic since 1991.

    After more than two decades, Sheila has handled just about every conceivable situation, and answered any question imaginable, but she is always up for a new challenge.

    As our head technician, Sheila also keeps track of supplies and equipment, from the surgical monitors that keep your dog safe under anesthesia, to the cotton balls we use to clean your cat's ears. Around the clinic, Sheila is affectionately referred to as 'The Voice of Reason'.

    Outside the clinic, Sheila works with cattle, tends her garden, plays with her farm cats, and shares her wicked sense of humor with family and friends.

    'I look forward to meeting you and working with your animal friends.'

  • Mittsy Voiles

    Mittsy has offered dog and puppy training classes at the clinic since 2007, and was hired as a behavior specialist in 2008. Her role is to make sure patients (and clients) have positive, low-stress visits to our clinic.

    She is passionate about shelter medicine, having worked in animal shelters since 1998, including as Animal Care Manager at Elmbrook Humane Society in Brookfield, Wisconsin.

    As founder and director of Good dog!, Queensland, Australia, 2003-2007, Mittsy developed and taught classes for puppies and adult dogs, focused on understanding behavior, preventing problems such as aggression and fearfulness, and providing proper care for the lifetime of the dog.

    Her specialty is canine behavior, but her training has been across many species, including cats, ferrets, chinchillas, and zoo residents including bats, parrots, wombats, chimpanzees, baboons and dingoes.

    Besides Australia, her travels have taken her to Iceland, New Zealand, Germany, England, Wales, Dubai, Canada, and all 50 U.S. States. Outside work, you can find her at one of Jefferson County's amazing parks.

  • Kelly Smart
    Certified Veterinary Technician

    In 2010, Kelly interned with us while in school for her Associate degree, and we hired her soon after as a Veterinary Assistant. After a brief move to Alabama, where she worked as a CVT in a local veterinary clinic, Kelly missed sub-zero temperatures and decided to move home to Wisconsin. We were thrilled to welcome her back, as a newly-seasoned CVT, in 2012.

    Originally from Oconomowoc, Kelly has been working in animal shelters and veterinary clinics for over eight years. While most of her work has been with cats and dogs, she is also comfortable with birds, rabbits and pocket pets.

    Kelly loves helping animals and seeing how happy and grateful their owners are. She is a proficient multi-tasker, and from the lobby to the laboratory, is quick to recognize where she is needed most in the building. She is always excited to meet new patients, and likes learning about unique and unusual cat and dog breeds.

    Don't fence her in! Outside work, you can find Kelly at the dog park with her yellow Labrador named Jake, running, biking, kayaking, playing volleyball, tennis, or pretty much anything outdoors. She and Jake also share their home with a black-and-white bob-tailed cat named Ava, adopted while Kelly lived in Alabama.
