Office Manager

Our patients are like family. We love to see wedding and baby pictures and hear about events happening in their lives. I love helping our patients attain their dental health goals and know how it can make them feel—it can be life changing! I am honored to be able to impact people’s health and lives. I am Wisconsin born and raised with much time spent horseback riding. My husband and I spend time at home with our dog, making wine, enjoying the outdoors and making memories with our God-Children, nieces and nephews.

I enjoy assisting Dr. Behringer & Dr. Casteel with dental procedures and making our patients feel comfortable. We have great patients and they make me smile! The Smile Clinic is like "family"...we share the same passion for dentistry and providing quality care to all our patients! In my spare time I enjoy reading, watching movies, camping, and playing the ukulele. I also have a Chihuahua named Charlie and a hedgehog named Lola.

My favorite quote is, "Nothing is Impossible...the word itself says "I'm possible." - Audrey Hepburn.


Clinical Manager

I enjoy helping patients smile every day. From our same day CEREC crown technology to putting apprehensive patients at ease with oral conscious sedation, nothing compares to the outcome of saving patients time and delivering care with little to no memory of their visit. Two teenage boys and an energetic young daughter keep Jeremy and I busy. We enjoy our annual trip to the Dells and seeing new places over our children’s spring break every year.
