Katelyn P. Sandfort joined Herrling Clark in 2020 after a decade of complex litigation practice at a Northeast Wisconsin law firm.  She was promoted to shareholder in 2022.  Katelyn completed her undergraduate studies at the University of Minnesota and went on to earn her juris doctorate from the University of Wisconsin.

Katelyn’s primary area of practice is representing injured people and their families when they have been involved in an accident or other injurious event.  The first ten years of her career, she defended personal injury actions.  Her past experience as a defense attorney provides her additional insight of what the insurance company on the other side of a claim will likely do, both pre-suit and in litigation.  She is able to use that advantage for her clients’ benefit while litigating and resolving their claims.

Katelyn has tried cases throughout the State of Wisconsin, from Milwaukee County to Eau Claire County and, of course, close to home in Outagamie County.  She is a member of the Wisconsin Association for Justice, as well as various local bar associations.  She is an active member of the WAJ Women’s Caucus and enjoys participating in continuing legal education opportunities that promote a deeper understanding of the laws that impact her clients while also supporting and encouraging other women in the practice of law.

In her personal time, Katelyn can be found with her husband and two young sons enjoying Appleton’s farmers market in the summer and spending their afternoons exploring area parks and trails.  She also has a spoiled Bernese Mountain Dog named Kiva.
