About Me

  • I grew up in Stevens Point, WI and attended Pacelli High School. I took great pride playing for their football team and competing in the state golf championship.

  • My interest in orthopaedic surgery began early in my childhood. My father and grandfather both practiced orthopaedic surgery in Stevens Point and through their patients (many of my neighbors and friends) I saw the significant impact their work had on being able to decrease pain, and return people to their goals and livelihoods.

  • In my personal life, I enjoy traveling and seeing new perspectives. I've been privileged to attend medical trips to Peru and Nicaragua, as well as study in Guatemala for 5 months while living with a host family. That being said, I love living in Wisconsin and very much enjoy its seasons, activities, and sports. Go Pack Go!
