“My Experience was nothing short of amazing. Seeing the difference between when I first started and now the end result is crazy, but none of that would’ve been possible without Doctor Kelly. She is very detailed and informative, and her personality is just the cherry on top. Any change with my braces she was quick to let me know what was happening, and on moments when she asked me to “trust her”, I’m so glad I did. Thank you, Doctor!”

“Dr. Harris is a very compassionate, caring doctor. You can tell she cares when you see her, she takes her time, doesn’t make you feel rushed, and listens to any concerns that you may have. She is treating my son and makes him comfortable and knowledgeable about what is going on. You get the feeling with her that she is treating you or your children how she would treat her own family. Highly recommend.”
