Dr. Chris Haase

DVM

Dr. Chris has been forging paths throughout both his academic career and professional care. His interest in immunology and veterinary medicine lead him to complete dual degrees. He sought out to complete a Masters and PhD in comparative biomedical sciences with a focus in infectious disease in the feline and canine, developing vaccinations and field testing vaccinations in large animals, and developing diagnostic test for identifying infectious disease in multiple species. This was all in addition completing his Doctorate in Veterinary Medicine. His interest in immunology, infectious disease, and comparative biomedical sciences including humans lead him to take additional training in both animal and human infectious disease, virology, immunopathology, hypersensitivity, and autoimmune diseases. On top of all of Dr. Haase's accomplishments, he is also a distinguished published author on multiple different scientific studies in the Veterinary field.

Wow, Right! What does this mean for his clients? Beyond the basic of a mixed veterinary practice he is very successful at treating hypersensitivity reactions, autoimmune disorders, and infectious diseases. He is sought by companies and the veterinary community to provide knowledge and information on vaccine protocols, disease management and more. Beyond his academic training he has training in surgery including general and orthopedic surgeries.

Outside of practicing veterinary medicine on both companion animals and large animals he is a business owner. He is one of the very few veterinarians that have started a veterinary business from scratch, starting with just a handful of clients and successfully building a large and expanding practice. He takes his business very serious, and strives to provide the community with trusted and respected veterinary service.

Dr. Anne Madden

DVM

Dr. Anne Madden was born and raised in the suburb of Hinsdale, Illinois, just outside of Chicago. She grew up with three older brothers whose names all started with the letter “M,” and to this day, it still makes her bitter that her name did not start with the letter “M” as well.

She went to St. George’s University in Grenada, West Indies, for the first three years of veterinary school and completed her clinical year at UW Madison. It was a really cool experience to do the first three years of veterinary school in the Caribbean, and without it, she would not have her two animals. She has an island dog named Bumi (he is 3) and a black cat named Finch (he is 2). Fun fact: her dog was saved from the Grenadian prison yard, and his whole litter was referred to as the “Jailbird Babies.”

From the time she was a little girl, she always knew she wanted to become a veterinarian; however, her parents did not allow her to have any pets (besides a carnival goldfish). She made friends with people who had dogs or cats and was known to check out the Dog Breeds Encyclopedia every time she went to the library. It is beyond thrilling for her to have those dreams come true!

She went to school to become a small animal internist but fell in love with cows and wanted to somehow incorporate them with dogs and cats. She is so excited that CJ Haase has given her that opportunity and cannot wait to start her career!

Dr. Sherri Roberts

DVM

Dr. Sherri Roberts joined CJ Haase Veterinary and Immunological Services in the fall of 2024 and is enjoying being part of a team of caring people. She was raised in the wide open spaces of North Dakota, attended Colorado State University in Fort Collins, CO for a bachelor’s degree in Wildlife Biology and then the University of Madison – School of Veterinary Medicine (2003). Whether it’s critters in nature or critters in homes, it’s where her connections to the rest of the world start.

She values the importance of the doctor-client-patient relationship for fostering better health for pets and their people. She has enjoyed the last 18 years in her own house call/mobile practice that allowed the time and space to learn that what’s important for a family leads to a better quality of life for everyone in the household community. Her own household includes her golden retriever, Grace, and Mr. Pickles, the cat. As Dr. Sherri’s human kids are growing up and starting to venture out on their own, she knows it was time for her to venture out as well – grateful to be here – every day filled with people and their animals is an adventure!
