For Dr. Lewis, North Atlanta is home. His philosophy is built on transparency: recommend only what is necessary and use advanced technology like iTero digital scanning to evaluate your alignment without messy impressions. Whether he is meeting a family from East Cobb at our Orthodontist office in Marietta or a student from Acworth at our Kennesaw practice, his focus remains on results that last.
We’ve positioned our offices to be convenient for busy suburban lifestyles. You’ll find our Marietta office centrally located near Lassiter High School, Mabry Middle School, and Shallowford Falls Elementary. Being just a 5-minute drive from these local schools makes afternoon appointments seamless for families in East Cobb, Sandy Plains, and the Shallowford area.
Additionally, our Kennesaw office serves the Stilesboro Rd corridor, while our Cumming location is situated right on Peachtree Parkway. These localized hubs allow residents in Cherokee, Cobb, and Forsyth counties—including Woodstock and Alpharetta—to access elite orthodontic care from the first digital scan to the day your braces come off.

Smiles don’t follow one schedule—they grow and change along with us.
Some kids come in early, just to see how their teeth are lining up.
Teenagers? They’re usually ready to jump into braces or Invisalign®.
And plenty of adults decide it’s finally time to do something for themselves.
A 7-year-old’s treatment plan won’t look like a 15-year-old’s or a 35-year-old’s.
That’s why we look at where you are right now, not just how old you are.
The American Association of Orthodontists recommends a first orthodontic checkup by age 7. Dr. Lewis can spot early signs of crowding, bite issues, or jaw growth concerns while your child is still developing.
Early care doesn’t always mean braces right away—sometimes we simply monitor growth. When early treatment is helpful, it can make future orthodontic care easier and more effective.
The teen years are often the ideal time for orthodontic treatment—most permanent teeth are in, and the jaw is still growing, which makes correcting alignment and bite issues more efficient.
We offer both braces and Invisalign® Teen, and we keep visits efficient and scheduling flexible for busy school and activity calendars.
More adults in Marietta, Kennesaw, and Cumming are choosing orthodontic treatment—whether to correct shifting after past braces or finally get the smile they’ve wanted for years.
Treatment works at any age. We’ll walk through options like braces or Invisalign® and build a plan that fits your timeline, comfort, and lifestyle.
We’re glad you found us. If you’re thinking about braces, Invisalign®, or just exploring your options, we’ll walk you through it step by step.
