The Dental Assistant is an absolute treasure! She immediately understood my son's anxiousness and spoke and worked with him in a fun, gentle, and collaborative way that put him at ease. We can't wait to see her again!

This is a major positive aspect of our treatment. Our orthodontist speaks directly to the patient (as well as parent who is nearby) about what procedure is about to be performed, what it will feel like for the next few days, why this procedure at this time, what they the next stage of treatment will be, and always asks AND answers questions and allays fear/trepidation with do-able solutions.
