I have been working in the field of orthodontics with Dr. Nissen since 1999. I was born and raised in St. Louis. I enjoy getting to know our patients, as we get to see them every month. In my spare time, I love to exercise as well as spend time with my family and friends. In 2013, I married my favorite orthodontic patient Joe!
