Resident IR-4

Jake grew up in Hartland, WI and attended the University of Wisconsin-Milwaukee where he majored in psychology and biology with a focus in neuroscience performing research on ischemia brain injury. He took a brief “sabbatical” to pursue snowboarding in Steamboat, Colorado for a year. Following college, he moved to Washington D.C. and worked at NIH conducting traumatic brain injury research. During this time he met his wife, Arrianne, and they eventually relocated to Madison so he could attend medical school at UW. With the amazing quality of radiology training/research at UW and fantastic quality of life that Madison offers they decided to stay for residency. Outside of work, Jake enjoys climbing, road/mountain biking, cross country skiing/biathlon, snowboarding, gardening, and fly fishing in his free time.

Resident IR-3

Elliott was born and raised in Ames, Iowa. He left home to study bioengineering at Syracuse University for undergrad. Having had enough of life outside of the Midwest, he returned to Chicago to attend medical school at Northwestern University, and stayed in Chicago to complete a prelim surgery year at St. Joseph Hospital. He dabbles a little in a lot and is down to try almost anything new. Established interests include any outside activity in any weather (including soccer, basketball, spikeball, hiking, boating, snow skiing, etc), playing board games, and cooking. As proud fur-parents of our cat, Maeby, Elliott and Libby hope to grow their fur-family with a dog after leaving the big city.
