Dr. Katie Halfen
I grew up in Somerset, Wisconsin and graduated from Northland College in Ashland, WI with a dual degree in Chemistry and Biology and then graduated from Tufts University School of Veterinary Medicine in Massachusetts in 2008. I became owner of Star Prairie Veterinary Clinic in June 2016.

I am currently living is Somerset with my dogs and cats. It has been nice to move back to Wisconsin after being away for 13 years.

I am an avid dog enthusiast and actively breed, train and compete with my German Shepherds. I have been a breeder for over 10 years. I train and compete with my dogs in AKC conformation, agility, obedience/rally, herding, and barn hunt with BHA.

My professional interests include reproduction (theriogenology), animal behavior, surgery and internal medicine. I am excited to have the opportunity to provide veterinary care to your pets and look forward to meeting you and serving the community. Please stop in to say hello and see our facility!
