Dr. Ellerhorst and Dr. Kieu work side by side to ensure that your treatment progresses in the most efficient manner possible. Their fun nature make each visit a pleasant and enjoyable experience and results in a higher standard of care.

  • Having two highly trained orthodontists, working side by side, allows for a greater standard of care. No patient is ever rushed, and there is always time to answer all of your questions. Collaboration allows for input in determining the most appropriate, customized treatment plan. Your input is always heard.
  • Our office is nearly 100% paperless. This is not only more environmentally friendly, but it enables us to have immediate, detailed information sharing with your dentist and any other health professional involved in your care. The end result is a more comprehensive, personalized plan.
  • Both Dr. Ellerhorst and Dr. Kieu are very proud of their commitment to continuing education always exceeding more than the amount required by law. This allows both of them to stay on the cutting edge of the most current, efficient methods of treatment, including Invisalign. You will not find an orthodontic team more dedicated to meeting your specific needs.
  • The San Mateo Orthodontic Group has recently teamed with Orthocad; a dental company that enables enhanced patient comfort and superior results in a shorter amount of time. Orthocad has developed an intra-oral scanner that takes the place of dental impressions; we are one of the only offices in the Bay Area that uses this technology. This means, traditional alginate impressions (the gooey material that can often activate the gag reflex) are not necessary; instead, unobtrusive photographs are taken with a wand inside you mouth. No mess, no gagging. The models are then stored digitally for easier, immediate sharing with your dentist. With Orthocad IQ, mathematical algorithms are used to place brackets on teeth with extreme accuracy, resulting in more efficient movement and a shorter amount of time spent in braces. The end result is a better orthodontic experience unique to our patients only.
