Stacie

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.

Lexi

Treatment Coordinator

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.

Gina

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.

Allyson

Treatment Coordinator

I enjoy the diversity of treatment we offer along with ensuring our patients are comfortable. It’s so rewarding! I also appreciate that our patients treat us like their own family. New Holstein is home where I live with my husband, Josh and adopted rescue dog, Mozart. Before settling in the dental field I spent time traveling in England and also enjoy traveling where ever there is a beach!

Heidi

My career in the dental field started over two decades ago, and I still love it! As a hygienist I enjoy creating relationships with my patients while educating them on good oral health. I'm part of an amazing team who all enjoy working together with the goal of making each patient's dental visit a wonderful experience. When I am not helping our patients I enjoy gardening, swimming, biking, snowmobiling and spending time with my family.

I am part of a dental team that shares the same goals - to provide the best care for our patients and build long-term relationships. We stay current with the latest dental technology and continuing education so our patients are always comfortable while receiving the best care available. Recently becoming empty-nesters, my husband and I are looking forward to exploring new activities and doing more traveling. Something that has always been on our bucket list is to cruise the Mediterranean Sea while visiting the adjacent countries.

My relationship with the Smile Clinic started as child when I was a patient of Dr.Behringer’s. I always enjoyed my dental visits and decided to become a hygienist! I have a personal connection with my patients and love it when they share stories about themselves and their family. In addition to having great patients my teammates are fun to work with. We're like a big, happy family! My husband and I enjoy time spent with our children whether we are watching them play sports or playing with them. We also enjoy going for walks, biking and boating.
