“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!”
