Becky, Patient Coordinator

Hi! My name is Becky. I joined Seim Orthodontics in June 2019. Prior to coming to this great office, I was a vet tech for 18 years. I have a profound love for animals and enjoy their companionship. Prior to that, I studied dental assisting and worked at a dental office upon completing school.

I am thrilled to be a part of the team at Seim Orthodontics. Dr. Seim is a dedicated, St. Charles county native who takes pride in treating the community where she grew up. Nothing compares to the bond built during treatment, and the new-found confidence and joy our patients have at the end.

In my free time, I enjoy being outdoors with my husband Shawn, my daughter Mady, and our two black labs, Clark and Eddie. We love hiking and watching the dogs swim at every chance they get. We also enjoy traveling and enjoying new experiences together.

Amy, Orthodontic Assistant

Hi! I’m Amy, and I’m so excited to be part of Seim Orthodontics! I joined the practice in August 2026, bringing with me more than 20 years of experience as an Orthodontic Assistant serving patients throughout the St. Louis area.

I truly believe orthodontic treatment should be an exciting and positive experience—not a stressful one! I love getting to know our patients, cheering them on throughout treatment, and watching their confidence grow as their smiles transform.

When I’m not at the office, you’ll usually find me spending time with my amazing family—my husband, Pat, and our two sons, Sean and Liam. I’m also a lifelong photography enthusiast who turned my love of capturing memories into a small photography business. I also enjoy crafting, watching sports with family and friends, and spending time outdoors with our two fur babies, Belle and Stitch.
