I started working as a Scheduling Coordinator in 2005. I organize our schedule so that each day is as smooth as possible. I love seeing our patients beautiful smiles when they are finished with treatment.  In my spare time I like to play volleyball and spend time with my wonderful husband and family. I have 20 wonderful grandchildren and they all make me smile!

My kids have been patients for years, and we have always enjoyed the friendliness and professionalism of the office. I joined the team in spring of 2019. I primarily set up new patient appointments, verify insurance and assist with other jobs around the office. My favorite part of the job is seeing patients gain confidence from a great smile! In my free time, I enjoy reading, baking and working on our 100 year old house in Labadie. I also enjoy spending time with my husband, Rich and our two children, Joseph and Elise.

In addition to assisting with all aspects of the clinical care for our orthodontic patients, I also manage the clinic to ensure our patients have the best possible experience. I absolutely love working in the orthodontic field and have been working in orthodontics for more than 35 years. It is so great to get to know our patients and watch how their confidence and self-esteem grow as their teeth straighten. All the time and effort put into their orthodontic care is always worth it in the end! In my spare time I enjoy walking, reading, sports, being outdoors, and spending time with family, friends, and my wonderful granddaughter, Andrea!
