Residency/Fellowship Program Coordinator

Kerry grew up in rural Iowa and is a recent transplant from Chicago, where she earned her Bachelor of Fine Arts in design in 2006 from Harrington College of Design. Spending 17 years in Chicago, she moved to the La Crosse area to be closer to family and the outdoors. Kerry is proud to work at Gundersen Health System. She is the residency and fellowship program coordinator for several programs in Medical Education, including the Sports Physical Therapy Residency.

"I find joy and fulfillment in working with learners and educators. The support that is offered for those on a team in any aspect of the patient care process, from administration to the residents and fellows, to the clinicians and educators, is amazing. Everyone is caring and genuinely has the patient experience at heart, but also those who support the providers and educators," Kerry says.
