Meet your St. Louis orthodontists

Experience you can trust. Care you can feel.

Two orthodontists, one shared commitment: thoughtful treatment, honest guidance and a patient experience that feels genuinely personal.

Orthodontist

Robert Shapiro, DDS, MS

Dr. Shapiro is known for a thoughtful, detail-driven approach and lasting relationships with generations of St. Louis families. He brings decades of clinical experience to each plan while making sure patients understand every decision.

His approach begins with careful diagnosis. Straight teeth are important, but the way the upper and lower teeth fit, the health of supporting tissues and the stability of the final result matter just as much. Patients and parents receive practical explanations rather than a one-size-fits-all recommendation.

Dr. Lisa Seim, St. Louis orthodontist
Orthodontist

Lisa Seim, DDS, MS

Dr. Seim combines modern orthodontic expertise with a warm, collaborative style. Her goal is to make every patient feel heard, comfortable and confident from the first conversation through the final result.

She values treatment plans that work clinically and practically. That means considering school, work, sports, family schedules and a patient's preferences alongside the bite correction. Her clear communication helps patients understand what is happening and why.

  • Personalized orthodontic planning
  • Modern digital treatment approach
  • Care for growing and adult smiles

Why choose an orthodontic specialist?

Orthodontists complete additional specialty education after dental school focused on facial growth, tooth movement and bite correction. That training supports diagnosis and treatment planning for simple alignment concerns and complex tooth or jaw relationships.

Whether your plan uses braces or Invisalign, the appliance does not replace clinical judgment. Your orthodontist determines the movements, monitors biological response and adapts the plan when necessary.

Care for children, teens and adults

Children may begin with an early evaluation and observation rather than immediate treatment. Teens need effective options that fit school, sports and hygiene. Adults often seek subtle treatment, renewed confidence or coordination with other dental care.

Dr. Shapiro and Dr. Seim treat every age at our Creve Coeur and Sunset Hills offices.

Collaborative treatment planning

Good orthodontic care is a conversation. We listen to what the patient wants to change, explain what the examination reveals and compare appropriate options. If multiple approaches could work, we discuss their advantages and responsibilities honestly.

When treatment intersects with restorative dentistry, periodontal care or oral surgery, our doctors can communicate with the patient's other dental professionals to support a coordinated result.

Begin with a complimentary consultation

The first visit is an opportunity to meet the team, ask questions and understand the possibilities. If treatment is recommended, you will receive information about the appliance, timing, fee, insurance and payment options before making a decision.

Learn what to expect at your first visit or contact either office to schedule.
