For Dr. Lewis, this community is home. His philosophy has always been simple: provide thoughtful, evidence-based orthodontic care using modern technology that improves both comfort and accuracy. Using advanced tools like iTero digital scanning, patients can see detailed images of their smile and avoid traditional messy impressions.
Whether meeting with families in East Cobb at our Marietta orthodontic office or helping patients at our Kennesaw location, Dr. Lewis focuses on creating healthy, lasting results designed to support long-term confidence and function.
Our offices are designed to make orthodontic treatment convenient for busy families throughout the area. The Marietta office is centrally located near Lassiter High School, Mabry Middle School, and Shallowford Falls Elementary, making after-school appointments easier for families in East Cobb, Sandy Plains, and nearby communities.
Our Kennesaw office also provides convenient access for patients throughout the Stilesboro Road corridor and surrounding Cobb County communities, including Acworth and parts of Woodstock. From your first consultation to your final retainer check, our team is committed to making orthodontic care straightforward, comfortable, and personalized.

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 and Kennesaw 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.
Every smile starts somewhere, and this is a good place to begin. Our team will help you choose a plan that fits your goals, your schedule, and your comfort level.

As a local orthodontist serving Marietta and Kennesaw, we focus on long-term results, honest recommendations, and care that fits real life.
No two smiles are the same. That’s why we take time to listen, learn what matters to you, and build a treatment plan that fits. You’ll always know why we recommend a certain approach and what results to expect — no guesswork, no one-size-fits-all plans.
We use the latest tools to make treatment more comfortable and precise — including 3D imaging and impression-free digital scans. The result? Fewer surprises, faster visits, and a smoother path to your new smile.
Braces, Invisalign®, TMJ care, corrective jaw surgery — whatever your needs, we can help. Whether you’re seven or seventy, we’ll guide you to the option that makes sense for your teeth, your goals, and your lifestyle.
