Johnston Orthodontics: Mark W. Johnston, DMD, MS

Orthodontics isn’t just about straightening teeth—it’s about aligning bites, correcting jaw positioning, and sometimes even reshaping facial structure over time. Johnston Orthodontics operates in this specialty, offering treatments that range from traditional braces to clearer alternatives for adults and teens. The practice handles everything from early interceptive care for children to more complex cases involving surgical orthodontics. While results vary by individual, the goal remains consistent: functional improvement paired with aesthetic refinement.

The office sits at 1070 Woodlawn Dr NE #200 in Marietta, a stretch of Cobb County where professional buildings mix with quiet residential pockets. This part of Woodlawn Drive is convenient for those coming from East Cobb or the surrounding Atlanta suburbs, though traffic along Johnson Ferry Road can get heavy during rush hours. Public transit options in the area are limited, so most patients arrive by car. The suite number places it on the second floor, which is standard for many medical offices in this corridor.

Scheduling an initial consultation is the usual first step, and the front desk fields those calls at (770) 973-1070 during business hours. For anyone mapping the route, the practice’s exact location is pinned here. Parking details aren’t listed, but the surrounding lot typically accommodates patient volume for offices in this building.
