  • "I cannot say enough good things about Dr. Dahar's office. I was treated as an adult patient, and was a difficult case to treat. My son was also treated by Dr. Dahar. Both of us are so pleased with our smiles. Dr. Dahar and his staff are so professional, accommodating and caring. I recommend Dr. Dahar to all my family and friends."
    Jennifer K.
  • "Dr. Dahar and his staff have treated all five members of our family primarily over the last ten years. Treatments have included everything from the run of the mill misaligned teeth to missing or misplaced teeth to orthodontic support for orthognathic (jaw) surgery. Dr. Dahar and his staff have been supportive and helpful throughout, and we are grateful to them for helping to create our beautiful smiles."
    K. Policastro
  • "Dr. Dahar is the best orthodontist in the area. After suffering from severe migraines from TMJ problems, Dr. Dahar's treatment changed my life. I no longer have debilitating headaches and I have a beautiful smile. Both of my daughters and I have received outstanding care and have had an all around great experience with his staff. I highly recommend choosing Dahar Orthodontics for treatment."
