Improving smiles of all ages in Moline, Clinton, and Geneseo


At Orthodontic Group Associates, we truly believe that smiles change lives! Our greatest goal is to give you the healthy, straight, and beautiful smile you’ve always wanted. Dr. Randall Welser and Dr. Kirby Marine understand that choosing to receive orthodontic care is a big decision, and we respect your reasons for wanting to improve the way you look and feel.

When you choose to receive orthodontic care from Orthodontic Group Associates, you’re choosing an honest, straightforward team of doctors who have your best interests in mind. We specialize in both one- and two-phase treatments, including Invisalign®clear braces, and traditional metal braces. By using a two-phase approach, we can work with a child’s natural growth and development to help resolve complicated bite problems early.

To accelerate orthodontic care, we have introduced the AcceleDent® Aura. When used in conjunction with Invisalign and traditional braces, AcceleDent Aura has been clinically proven to move teeth up to 50% faster.

At your first visit, we will take time to get to know you and discuss your or your son or daughter’s orthodontic needs and desires. Each team member strives to make your experience with us enjoyable and stress-free. Our treatment coordinators and orthodontic assistants are professionally trained to assist our doctors with every stage of your treatment, while our financial and scheduling coordinators are here to assist you with appointment scheduling and insurance or payment questions.

We invite you to contact our Moline, Clinton, or Geneseo offices to schedule your complimentary consultation. It is our privilege to make a difference in in your life by creating a beautiful, unique smile for you.
