Dr. Sarah Lautzenhiser
Dr. Sarah has been a small animal veterinarian for over 20 years. She grew up in Madison, Wisconsin, and was a first-generation college student. As a child she loved all things animal and artsy, and was known to draw and paint, as well as play musical instruments; she was also in dance and performed with the Wisconsin Youth Symphony Orchestra and the Madison Ballet Academy. One of her art pieces was on display at the Humanities Building in Madison as part of a Youth in Art project.
Hard work has never been something Dr. Sarah has been afraid to jump into.
After graduating high school from Madison East at the top of her class, Sarah pursued a degree in Bacteriology from the UW-Madison, then completed the DVM program at the UW-School of Veterinary Medicine in 2000. Dr. Sarah went on to pursue additional/specialised training via internship programs at Michigan Veterinary Specialists and Affiliated Veterinary Specialists. After spending 20 years of her life working on her education, Dr. Sarah decided to finally get a haircut and get a real job.
Dr. Sarah cut her veterinary teeth working in emergency clinics in Chicago and then Appleton. While she found emergency work rewarding, the hours are often grueling and climbing that career ladder was not in the cards for her. In her 4th year out of school, Dr. Sarah decided to try being a general practice veterinarian – not something she envisioned herself ever doing.
In the following years, Dr. Sarah gained experience working in general practice, and continued to moonlight doing emergency work as opportunity permitted; she went back to full-time emergency work in Milwaukee and held a job in Wausau at the same time, to prepare to own her own clinic.
In 2009 Dr. Sarah signed the largest note of debt in her life and bought the Antigo Veterinary Clinic. “My motivation to become a practice owner was largely because I wanted to have more of a say in things like medical and surgical protocols, standards of care, and the hospital culture.”
In 2010 she founded the non-profit, “Antigo Area Advocates for Animals”, a 501c3 organization providing a Trap-Neuter-Return program to Antigo and surrounding communities.
In 2010, she also started the Antigo Veterinary Clinic “Angel Fund” to help impoverished pet owners with pets in need.
In 2015, Dr. Sarah obtained certification as a Humane Officer. She has also assisted in cases of animal abuse and neglect in Langlade County and Forest County.
Dr. Sarah’s areas of expertise in small animal practice include urgent/emergency care, internal medicine, soft tissue surgery, ophthalmology, ultrasonography, dentistry, and endoscopy. She particularly enjoys working with senior patients and forming long-term bonds with families and their pets.
Outside of work, Dr. Sarah enjoys gardening, hiking, kayaking, and fishing, making art (painting, beading), and spending time with her fur-fin-and-feather kids including 3 dogs, 3 cats, 2 Indian Ringnecks, 2 Sebastopol geese, and numerous freshwater fish in tanks including African Cichlids.
