Welcome To Chapman Smiles

No dentist referral needed!

ChapmanSmiles Orthodontics is a modern but established orthodontics practice located in Happy Valley Oregon. Founded and operated by orthodontist Gary Chapman, DDS, the practice is dedicated to treating patients with the highest quality care in a relaxed, fun, and friendly environment.

Dr. Chapman and the team at ChapmanSmiles Orthodontics believe everyone deserves individualized care. They never recommend treatment before a  full orthodontic evaluation. To ensure their patients always receive quality care, the practice offers free initial consultations for every new patient.

Best orthodontist ever. Always very easy to let them know your there for an appointment and it’s never a long wait. Comfortable and clean environment. I love talking to everyone there, they are all chill. It is super easy to reschedule and appointment with them and I never have had any issues with anything at Chapman Smiles! I might be glazing a bit but seriously, best orthodontist. When I first went in to figure out what exactly I needed, it was very informational. (My mouth was kinda messed up) but after having the MARPY on for 6 months my mouth was a lot better. The whole process has been easy and intuitive and I would definitely recommend.

LIFE CHANGING! I came to Chapman Smiles as an adult with clenching/grinding/TMJ and bite issues. I was in serious pain and my teeth also had wear/chipping from being out of alignment. Dr. Chapman developed a comprehensive treatment plan including a bite splint and clear aligners. The end result is that I am now pain-free and have the smile I have always wanted my entire life! I am forever grateful for Dr. Chapman and the wonderful, positive staff. Will be returning soon for orthodontic treatment for my son. Thank you Chapman Smiles!
