I have been an orthodontic assistant since 2021. I love to interact with patients and watch their smiles transform. I am happy to have found my "Ortho Family" at Dr. Walker's office.

"Terrific staff — everyone is always friendly; Missy loves the decorations, and they are always punctual. Dr. Walker has been helping me keep my teeth from moving. I wore braces much earlier in my life. I am extremely pleased with the help he has given me."
