Meet Dr. Lisa Seim

Seim Family | Klondike ParkDr. Lisa Seim was born and raised in the St. Charles area and is honored to serve her hometown. She became interested in orthodontics when she had braces as a teen. As an orthodontist, she loves getting to know her patients and watching them gain confidence, just like she did.

Dr. Seim attended St. Louis University, where she received degrees in Nutrition & Dietetics and Biology. She received her Doctorate of Dental Surgery (D.D.S.) from the University of Missouri-Kansas City School of Dentistry. She graduated at the top of her dental school class with Magna Cum Laude recognition. Dr. Seim earned her Orthodontic Certificate and Master of Science in Dentistry (M.S.) at St. Louis University Center for Advanced Dental Education. During her residency, she had the unique opportunity to complete a fellowship with Washington University’s Cleft Palate and Craniofacial team at St. Louis Children’s Hospital.

Dr. Seim is committed to excellence in education and is an active member of the American Dental Association, the American Association of Orthodontics, the Missouri Dental Association, the Greater St. Louis Dental Society, the Orthodontic Education and Research Foundation, and the WSCC Chamber of Commerce. Dr. Seim also supports philanthropy in the community. Seim Orthodontics is proud to work with Smiles Change Lives, a non-profit organization that helps children whose families cannot afford the full cost of braces. Every child deserves to feel good about their smile!

Outside of the Practice

Dr. Seim loves spending her free time with friends and family, including her husband, two sons, and their two Bernese Mountain Dogs, Bear and Barli. You’ll find her paddle boarding, hiking, and checking out local coffee shops and craft breweries in her free time. She and her husband-who owns a chiropractic practice in the same building as Seim Orthodontics-also support two children in Kenya through a program called Mercy’s Hope.
