Allentown Orthodontist, Dr. Philip Tighe, and his family have been creating healthy, beautiful smiles in the Lehigh Valley for over 40 years. In that time, two generations of Tighe Orthodontists have worked together to build one of the most respected orthodontic practices anywhere, right here in Allentown, PA. Today, we offer leading edge technologies, like the Invisalign® System, in an office that patients say feels more like visiting friends than going to the doctor. We believe that changing your smile has the ability to change your life in so many positive ways; from increased self-confidence to improved overall health. But that’s easy for us because we see it happen every day. Ready. Set. Smile.
