Providing Exceptional Veterinary Care to Our Community Since 1981
Oconomowoc Animal Hospital is a well-established, full-service, small animal hospital serving the Oconomowoc community since 1981.
In August 2014, Dr. Katrin Witz purchased the practice from its founder, Dr. Lauridsen, and has carried his standard of care forward. A graduate of the University of Wisconsin School of Veterinary Medicine, Dr. Katrin values patient care and client education and strives to practice with integrity, treating each animal as her own. She is an active member of the Wisconsin Veterinary Medical Association and the American Veterinary Medical Association.
Rooted in Oconomowoc
We are members of the Oconomowoc Chamber of Commerce and proud sponsors of the Oconomowoc Farmers Market each summer. Many of our clients live in Oconomowoc, Dousman, Ashippun, Watertown, Ixonia, Sullivan, Summit, Delafield, Hartland, Pewaukee, Rubicon, and Eagle — and a good number have been with us for 25 years or more.
Why Pet Owners Choose Us
We are collaborative with pet parents and with each other. That means talking through options and pricing before we move forward, taking the time to build a thorough clinical picture, and never rushing an appointment.
Our doctors use low-stress handling techniques, and our in-house laboratory means bloodwork and diagnostics are usually run right here, so treatment can start sooner. Our surgery suite runs Monday through Friday, and for orthopedic repairs and complicated soft tissue procedures, we work alongside a traveling board-certified surgeon who comes to us.
Beyond routine wellness care, our team offers services that are harder to find nearby — including veterinary spinal manipulation therapy, cold laser therapy, and care for reptiles alongside dogs and cats.
