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. Tuttle completed his undergraduate at Iowa State University receiving a Bachelors of Science in Animal Science in 1997 and a Bachelors of Science in Zoology in 2001.  He obtained is Doctorate of Veterinary Medicine with honors from Iowa State University College of Veterinary Medicine in 2005.  Following graduation from Veterinary School he completed a one year rotating Medicine and Surgical Internship at Michigan State University.  Beginning in 2006 he began and completed a three year Surgical Residency at The University of Wisconsin-Madison.

During his residency he not only had intense training in Veterinary Surgery but also received advanced training in Anesthesia, Radiology, Clinical pathology, and Internal Medicine and Critical Care.  He also was responsible for the teaching and training of veterinary students during this time.  In 2010 he received his Board Certification from the American College of Veterinary Surgeons.

In 2009 he began a position at The Veterinary Specialty and Emergency Center located in Overland Park, KS where he worked as a Veterinary Surgeon as part of a busy specialty hospital until taking a position with the Animal Emergency and Specialty Center in 2014 where he continued to perform duties as a Board Certified Veterinary Surgeon.
