Dr Mariel Cotton | Weldon Orthodontics, Weldon Spring MO

Meet Dr. Mariel Cotton

Mariel Cotton, D.M.D. & M.S.D.

Dr. Mariel Cotton graduated in 2010 with her bachelor’s degree in science and business from the University of Notre Dame. From there she attended Dental School at Southern Illinois University and graduated Cum Laude. She then expanded her dental expertise by completing an orthodontic residency at the University of Colorado followed by an Aligner Intensive Fellowship.

Dr. Mariel Cotton

Dr. Cotton decided to become an orthodontist because it is the perfect blend of art, science, and helping others. She was inspired by her grandparents who instilled in her the importance of finding beauty in all things and to love the creative process. Her parents also played a major role in her decision by both being in the medical field. This taught her to always be curious and to never stop learning. Being an orthodontist allows her to achieve all these things and more.

As an orthodontist Dr. Cotton is passionate about being a part of her patients’ smile journey. She especially enjoys early treatment and clear aligner therapy because of the creative challenge this treatment provides. She loves that she is not only able to improve her patient’s oral health, but also their confidence through orthodontic treatment. Her central goal is to make her patients feel at ease and excited about their treatment. One thing she wishes she could tell every patient is that everyone deserves a beautiful and healthy smile that they love to share with others!

Dr. Cotton currently resides in the greater St. Louis area with her husband Zach and their 3 rescue cats. They decided to settle down here because they love being close to their family and friends. In her free time Dr. Cotton loves to read and spend time outdoors hiking and exploring national parks with her husband. So far, they have been to 17 national parks. An interesting fact about her is that she helped to reconstruct the skeleton of a triceratops while volunteering at the Burpee Museum of Natural History.
