Starting orthodontic treatment for the first time can be like arriving in a new country—you know it’s going to be worth it in the long run, but sometimes it’s like you’re all speaking a different language. At Duo Orthodontics, we listen to your needs—we seek to understand, not just respond. We are fluent in English, Portuguese, and Spanish. We’re listening to your needs, your desires, and your lifestyle. Our office is trilingual because we want to understand our patients, both literally and culturally. Now we’re talking.

Our practice is built around the needs of our patients. We offer Invisalign® and Invisalign Teen® clear aligners, as well as metal and clear braces for all ages.

We aim to provide gentle and effective orthodontic treatments to create the smile you have long dreamed about.

We are proud to serve families in Atlanta, Marietta, Athens, Sandy Springs, Kennesaw, Roswell, Tucker, Jefferson, Watkinsville, Chamblee, Brookhaven, Dunwoody, Smyrna, and all points in between!

I want to express my deepest gratitude to two outstanding orthodontists and also to everyone who was involved in my daughter’s treatment. Today is the day we are down to the final wire. My daughter’s teeth are beautiful and most importantly, she has a healthy smile that will last her a lifetime. Thank you so much for caring about my daughter! - Richard
Thank you for all of your generosity and hard work that went into my braces treatment. All of you helped in one way or another and I am so grateful! Thank you for my new smile. I love it! - David
