    About me

    Hometown: Moline, IL
    Academic interests: Education, Mentoring, Ultrasound, Simulation, Research
    What you enjoy most about the program: Easy...the people...our residents, staff, and faculty are all heavily invested in the program and each other. I love the family atmosphere and collective drive to be innovative in what we do.
    Favorite things to do in Springfield:​ Enjoy Washington Park with my family, catch a movie at the Route 66 Drive Inn, pork chop & a corn dog at the State Fair (with a deep fried snickers to top it off!)
