Meet your Orthodontist

L. Sean Mullins, D.D.S.

As an orthodontist, I love seeing the transformations each of my patients goes through. At work, the best day is the one when we remove a person’s braces and they see the finished smile for the first time. The joy on their face, as they compare their before and after photos, and how astonished they are, never gets old. It is truly a blessing to be able to make this type of difference in someone’s life! learn more

Welcome to L. Sean Mullins Orthodontics


Dr. L. Sean Mullins and our orthodontic team believe you deserve a healthy, beautiful smile that fills you with confidence. We’d love to be your partners in creating that smile. We offer gentle, proven care, tailored to your needs.

At your complimentary consultation, Dr. Mullins and our team will ask about your smile goals. Then, following your exam, we’ll review the doctor’s proposed treatment plan. We’ll answer your questions, explain the options, and ensure you’re able to make an educated decision.

Our team members are experienced professionals. We’re also friendly, warm, and patient-focused in all we do. We want to get to know you as a person; we’ll always remember your name and our last conversation. We love helping our friends develop incredible smiles and would love to help you, too.
