Why is our orthodontist in Marietta & Powder Springs different?

What if you and your child genuinely knew you were loved and cared for deeply by every person at your orthodontic office? You see, our practice isn’t really just about braces (although our patients tell us we’re really good at what we do!)…And after all, there are hundreds, if not thousands of orthodontists in the North Atlanta area who can do what we do…But what makes us different, is our approach!!

So why choose us? Simply put, our practice is more than braces and smiles. It’s about heart. It’s about love, trust, and confidence. We exist to be a welcomed addition to your child and teen’s life, and you’ll feel it from the minute you walk in our office. Welcome to Due West Orthodontics with locations in Marietta and Powder Springs.

Dr. Smith and the team at Due West Orthodontics are amazing! I did Invisalign through them and not only did they provide me options that would fit within my budget, but they also went above and beyond to accommodate my wedding schedule. They allowed me to take a “break” from Invisalign by removing all of the attachments for several months while I had wedding events, then resumed my treatment after all of that was over. I am very pleased with how my teeth look now that I’ve finished treatment, they were able to fix issues I didn’t even know I had! Their offices are clean and nice, I never had to wait very long to be seen, and all of the staff were incredibly friendly and accommodating. I would not hesitate to recommend them to a friend.

The staff and Dr. Smith are very professional, polite, welcoming, and thorough. I am excited about my new smile journey. After having my braces off since high school, starting Invisalign as an adult, I was a little nervous. However, everything looks and feels natural. I am super excited about the results to come

-Michaela Williams

I love this practice! Dr. McClendon and Dr. Smith did a great job on my teeth and the ladies in the office are fabulous. Each and every one of them knew me by name or would just give a smile and a warm hello every time I saw them. Just super friendly. Besides being friendly they straightened my terribly crowded and crooked teeth. I’m very happy with the result! Thanks to all of you!! (PS ignore the crazy face I’m making in pic 1 – ha ha!)

Took my daughter to Due West Orthodontics on Dec. 23, 2020. The staff was so welcoming when we entered. They follow very good safety measures for Covid prevention. They took our temperatures and asked us questions to ensure we haven’t been exposed. They got us back fast and scanned her teeth. The orthodontist was friendly and personable which we liked. He explained in detail what he could do for her in straightening her teeth with Avisalign, the length of time it should take and answered all her questions. The assistant in the room was also very friendly and answered anything she could. So it’s a relaxed environment where you don’t feel rushed and you don’t pressured. The waiting area as well as the rooms are very upscale and super clean. The staff when we left was very friendly and I noticed they seemed to know the existing patients as they were greeted coming in like family. I am looking forward to my daughter Lindsey getting her teeth done there with the best of care and confidence.

-Kayla Alexander

Being a former patient myself, it was a no brainer when I had to choose an ortho for my family. The level of care is above and beyond. And I am continuously recommending Due West when others ask for help in choosing a provider. Keep up the great service.

-Valerie Jones

What’s not to say positive about this office and their wonderful team? So friendly and welcoming, I’m super glad I was referred. It’s a distance from where I live but it’s totally worth it. I brought my daughter here for braces and the past two times she’s been seen by Yvonne. What a nice, gentle person. Great customer service and positive attitudes from everyone there. Can’t ask for anything more ☺️

-Marissa Cooper

Dr Smith is a great orthodontist, very patient and is extremely outgoing. Answers any questions/concerns and is always happy to help.

-Jerren Nixon

My Invisalign experience with Dr. Smith and staff has been a pleasure. Dr. Smith asks thoughtful questions that show he clearly wants to design the best treatment plan for the individual. The staff is very friendly, knowledgeable and timely for appointments. The results are exactly as requested. I would highly recommend Due West Orthodontics.

-Christina Meeks

I’ve been to 3 orthodontists over the years and Due West Orthodontics has been the BEST! This is big compliment since the other 2 Orthodontists we’re also excellent but the care I’ve received here is just superior to the others! I HIGHLY RECOMMEND THEM! Special thanks to Yvonne for always being nice to me!
