Second Year

Portrait of Jessica BoettcherJessica Boettcher, DO grew up in Nebraska and studied Exercise Science at Creighton University before attending medical school at Des Moines University. It was during medical school that Jessica realized her interest in underserved communities and this drew her to an Internal Medicine Primary Care program based at John H. Stroger Hospital (formerly Cook County Hospital) and Rush University in Chicago. She became fascinated with Infectious Disease after rotating through the HIV inpatient service at Cook County. It was during that rotation where Jessica found her first true mentor, an ID attending, who inspired and encouraged her to pursue a career in Infectious Diseases. Jessica stayed on at Cook County Hospital for a chief year to strengthen her clinical and teaching skills. She looks forward to training at the U of M where she will have an academic experience as well as be able to continue caring for underserved patients. She is excited to continue her career in teaching as she loves working with learners of all levels. At this point, Jessica is most interested in HIV primary care, STIs and public health, but she is excited to explore Infectious Disease in its entirety and see where this path takes her! When she is not busy with fellowship, Jessica is trying to learn the ropes as a new (old) homeowner, outdoor/indoor gardening, training her crazy dog, or biking about and exploring Minneapolis/St. Paul.

Portrait of Ashley HusebyeAshley Husebye, MD grew up in Minnesota and completed her undergraduate work in biology at St. Olaf College. After spending a year volunteering with AmeriCorps, she went to medical school at Creighton University in Nebraska. She completed her Internal Medicine Residency training at Hennepin County Medical Center in Minneapolis, MN and enjoyed working with the underserved patient population. Ashley is interested in general ID, HIV, and antimicrobial stewardship. When she is not working, Ashley enjoys hiking, camping, and running with her dog, Thomas.
