Welcome to

Lake Mills Veterinary Clinic

Our clinic in a nutshell...

As one of only a handful of clinics across the country with a full-time behaviorist on staff, we blend our medical expertise with advanced behavioral skills, and this makes a big difference for you and your pet. From helping your dog bravely step on our lobby scale, to coping with the noises and strange body positions of taking an x-ray, and everything in between, a behavioral approach can turn hisses into purrs, and growls into wags.

Beyond a full-service veterinary clinic, we provide wellness care, dental care, and soft-tissue surgery. In partnership with a local specialist, we also offer in-clinic orthopedic surgery. With comprehensive in-house laboratory and radiology equipment, and access to countless external laboratories, research facilities and specialty providers, our doctors diagnose and treat cats, dogs and cattle, along with occasional horses, goats, rabbits, guinea pigs, chickens and other animals in need of care.

Our team offers a combined 200+ years of experience in animal care and veterinary medicine. We have achieved certifications and specialized training in fields including behavioral therapy, veterinary dentistry, canine ophthalmology, surgical anesthesia, phlebotomy, and dermatology.

While we are not an emergency clinic, we do have a doctor on call and provide emergency services as needed, including referrals to skilled regional emergency clinics. We also provide emergency care and regular herd health visits for local Wisconsin farms.

  • Gregg Stephan,

    A graduate of Jefferson High School, Dr. Gregg Stephan learned to pregnancy-check cows behind Dr. Ed Detmers, shortly before Dr. Stork. His early years in practice were spent in Elkhorn, Wisconsin, until 1994, when he established the Animal Hospital of Sun Prairie. During his tenure, Sun Prairie grew from burb to a city, and AHSP grew into a state-of-the-art hospital. After 23 years at the helm, in the face of family matters and management fatigue, Dr. Stephan stepped down from the practice he established, knowing he still had some gas left in his tank.

    The kindest and most compassionate staff. Dr. Stork is always wonderful with all my pets.

    -Danielle B.

    Our dog has been a patient here since she was first brought home at 8 weeks old (Dr. Clarke stayed late on a Saturday to give my puppy fluids while I cried holding my baby dog). Our sweet Dog will now be 12 years old on Feb. 27th. We love this clinic and all they have done for us and our sweet dog.

    -Melissa Dunnavan F.

    The best staff around! We are so happy we found this clinic when we moved up here. Everyone takes the time to answer any questions you may have and makes sure your pet is taken care of as opposed to your wallet taken advantage of. We can't say enough about how we appreciate everyone at this clinic. :)

    -Ashley Koncz W.

    I love going to the vet! It is my Disney land. The staff is wonderful and they all give me tasty treats and belly rubs.

    -Lola F.
