I can't put into words how pleased I have been with Dr. Harrington and his wonderful staff! Everyone is knowledgeable, helpful and friendly. A friend had recommended Dr. Harrington to me years ago and since then, all 3 of my children and myself have been through treatment. The kids had pretty straight forward cases (braces for all 3 in addition to a lip bumper for one) that all resulted in beautiful smiles after treatment was completed...and mine was a little more complicated at 43 years old, involving coordination with my surgeon for jaw surgery over the course of the two and a half years of treatment

Definitely the practice to choose. Front office staff is amazing - so accommodating, friendly and helpful, and the orthodontic care by Dr. Harrington and his staff is stellar. The before and after photos are unbelievable. The practice is excellent and they try to keep it fun. This is the orthodontic practice with all the bells and whistles. Between 2 kids (one with a 2 stage process), I've been a loyal customer for a very long time. You can tell Dr. Harrington has his patients' best interests in mind.

The staff are all very kind and help my daughter feel at ease. They patiently answer all of her very curious questions, because she wants to know exactly what they are doing, and they are fantastic at explaining things so she can understand and so it's not at all scary. They've put me at ease too! Dr. Harrington is wonderful. I've shopped around and found that his approach is appropriately conservative, meaning that he is not going to recommend drastic procedures when something simpler is sufficient.I see him considering where my daughter is developmentally and how her teeth and skull will change
