Our Veterinarians

  • Dr.
    Kurt Walter- Hansen
    Owner, Veterinarian

    In 1985, Dr. Walter-Hansen bought a little house that had been built way back in 1915. After considerable remodeling, he turned it into a functioning hospital, and Shamrock Animal Hospital was born. As the clinic grew and the many pets of Rosemount came to receive care, it wasn’t long before Kurt realized they were going to need a bigger facility! They moved into their new building in 1996, where the hospital still is today.

    Dr. Hansen received both his Master’s in Animal Science and Economics and his DVM degree from the Royal Veterinary and Agricultural University in Copenhagen, Denmark. In 1981, he completed a clinical internship at Iowa State University before completing a one-year clinical residency in Field Services at the University of Minnesota in 1982. In 1990 and 1994, he completed advanced course work in orthopedic surgery at Ohio State University—this allows Dr. Hansen to better help pets hurt by trauma. He’s also one of a few practicing veterinarians in Minnesota certified to perform the advanced TPLO (Tibial Plateau Leveling Osteotomy) and TTA (Tibial Tuberosity Advancement) surgeries. In addition, Dr. Walter-Hansen serves as an Adjunct Instructor at the University of Minnesota’s College of Veterinary Medicine!

    Outside of veterinary medicine, Kurt is a self-proclaimed “project magnet.” He often works on building construction and other challenging endeavors. He also enjoys traveling with his wife, working on his country farm with a menagerie of animals, and spending time with his children and grandchildren.

  • Dr.
    Patricia A. Walter
    Owner, Radiologist

    Like her husband and partner in ownership, Dr. Patricia Walter received her DVM degree from the Royal Danish Veterinary and Agricultural University in Copenhagen, Denmark. After graduating, she owned her own small-animal practice in Copenhagen while also working in the radiology department at the University. She was board-certified by the American College of Veterinary Radiology in 1984 after completing a clinical residency and a Master’s degree in radiology at the University of Minnesota’s College of Veterinary Medicine. She was even a faculty member at the University from 1985-2003, during which time Shamrock Animal Hospital was founded!

    Patricia has a special interest in abdominal ultrasonography and pulmonary radiography, and has contributed many scientific articles and textbook chapters to veterinary literature. Currently, she owns Veterinary Diagnostic Imaging, Inc., which provides continuing education, telemedicine, and referral ultrasound services to other veterinary practices.

    Dr. Walter lives with her husband on a farmstead in Rosemount, where they share their lives with three rowdy terriers, three mischievous cats, and three comfortably retired horses. When time allows, Patricia enjoys traveling with her husband, gardening, searching for antiques, and spending time with her two energetic granddaughters.

  • Dr
    Michelle Tholl
    Associate Veterinarian

    Dr. Michelle Tholl graduated from the University of Minnesota’s Veterinary College in 1998. After graduating, she practiced small animal and exotic animal medicine, as well as emergency medicine part-time for 15 years. Dr. Tholl was involved with an at-home euthanasia service for a few years as well. Prior to joining our team, Dr. Tholl co-owned a private small animal practice in Burnsville for 15 years. Dr. Tholl says, “The best part of practicing medicine, for me, is seeing the unique connection of each pet to their family, and to help that connection last as long as possible.” Dr. Tholl joined the Shamrock family in November of 2018.

    Michelle lives in Burnsville with her four children (two boys and two girls), three dogs (Shih Tzu, Borzoi and Australian/husky mix), and two cats. She has been a member of AVMA and MVMA for most of her career.

    When time allows, Dr. Tholl enjoys kick-boxing, running, perennial gardening, art, music and theater, as well as spending time with her children.

In July of 2019, Dr. Smith made the move to Minnesota and joined Shamrock Animal Hospital.
