If you add together an interest in science and a love of animals, Dr. John Silbernagel is the end result. “I grew up on a North Dakota ranch with a lot of animals,” Silbernagel says. “And even though I initially planned to work with large animals, I fell in love with surgery, which guided me to where I am today.”

Dr. Silbernagel graduated from Iowa State University College of Veterinary Medicine, and completed his residency at the University Of Illinois College Of Veterinary Medicine in small animal surgery. He worked at 24-hour-a-day hospitals and referral centers in Illinois, and Indiana. He later moved to Wisconsin and opened a specialty and emergency care facility several years prior to founding Madison Veterinary Specialists.

Dr. Silbernagel is a board-certified small animal surgeon, and a member of the American College of Veterinary Surgeons, Veterinary Orthopedic Society, American Veterinarian Medical Association, Wisconsin-VMA, and Dane County-VMA. He appreciates the collaboration found at multi-specialty emergency facilities which “offer the highest level of care to clients and their pets by allowing different disciplines to consult with each other on the same case.”

When not working, Dr. Silbernagel can often be found spending time with family — camping, biking, skiing, or enjoying other outdoor activities. He also considers himself a “foodie,” and enjoys cooking up new recipes in the kitchen.

Dr. Shriwise obtained her undergraduate degree in Zoology at UW-Madison before taking a year off to live in California and work with sea otters at the Monterey Bay Aquarium. After confirming her love for the field of animal care, she returned to get her veterinary degree through UW-Madison. She then completed a one-year rotating internship at NC-State (where she earned the “Intern of the Year” award), and came back to the UW-Madison for her three-year small animal surgical residency (where she also earned the “Resident of the Year” award). During internship and residency, she was involved with research on pain management and diagnosis, a novel surgery for correction of chylothorax, and fracture complications.

After finishing residency in 2019, Dr. Shriwise worked at MedVet Chicago, a large specialty center in Chicago. She then relocated back to Madison with her husband and two children and started at MVS in October 2022. She loves all surgeries, but especially enjoys thoracic procedures, minimally invasive options including laparoscopy and arthroscopy, surgical oncology, and soft tissue reconstructive surgeries. 

When not doing surgery, Dr. Shriwise enjoys playing Ultimate frisbee, climbing, doing pottery, and spending time with her family – including a 16-year-old Rottweiler mix named Monk.
