“I recently went to Smile Doctors Orthodontics in Harker Heights and my experience was AMAZING front start to finish. Everyone there was so nice and welcoming especially Meghane. We had a one-on-one conversation where she explained both treatment types (braces or Invisalign) and was able to help me choose the best for me. She was super helpful and was able to answer all my questions and concerns. I did not once feel rushed during this whole process. I would definitely recommend coming here if you want to start your journey on perfecting your smile!”
