Danielle

Office Manager

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!

Administrative Assistant

I joined OCSL in 2010. I am from Venezuela and came to St. Louis in 2007. Dr. Nissen and his team made me feel at home from day one. I love working with kids and enjoy speaking Spanish with our Hispanic patients. I love to travel with my husband, but that’s on hold for now since we are busy taking care of our two beautiful kids who are just 15 months apart!

I joined the OCSL team in 2020, and everyone has made me feel right at home. I love being an orthodontic assistant and learning new things from Dr. Nissen every day.
