Looking for an orthodontist in Marietta, Kennesaw, or Cumming? Dr. Glenn Lewis and our team have been here for families since 1987. That’s almost four decades in the community—long enough to know that every smile (and every schedule) is different.
We help kids, teens, and adults. Braces or Invisalign®. Full treatment or something more limited. We’ll talk through it together and choose what makes sense for you—not what sounds good in a brochure.
Not sure whether to see an orthodontist or your general dentist for braces? Here’s a quick explainer.
North Atlanta is home for Dr. Lewis. His approach is simple and a little old-fashioned in the best way: recommend only what’s necessary, explain the “why,” and set honest timelines. No pressure. No mystery.
During your consultation, we’ll look carefully at your bite and alignment, share options in plain language, and answer questions—the small ones and the big ones. Some patients are ready to start comprehensive care. Others benefit from waiting or a lighter touch. Either way, you’ll leave with a clear plan and room to decide.
You’ll find our orthodontic offices in Marietta (near Lassiter High School), Kennesaw (along the Stilesboro Rd corridor), and Cumming (right on Peachtree Parkway). As a local orthodontist serving North Atlanta, these locations make regular visits easier for families across East Cobb and West Cobb, as well as nearby communities like Acworth, Woodstock, Alpharetta, and throughout Cherokee, Cobb, and Forsyth counties.
Families often come to us when searching for an orthodontist near home, school, or work — and having multiple North Atlanta locations helps keep treatment convenient from start to finish.

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.
