The engineer behind the seal.
Oakline Structural Engineering is Cody Johnston, PE, MBA — an engineer who worked construction before he ever sealed a drawing, and who still believes the best engineering is the kind a homeowner can understand and a crew can build.

From the crew to the seal
Before he was an engineer, Cody worked in construction. That order matters: he learned how houses actually go together — the sequence a crew frames in, the details that get built easily and the ones that get built wrong — before he ever sized a beam. It shows up in every Oakline drawing set: details a real crew can build, in a real sequence, without guesswork.
The engineering came next: a Bachelor of Science in Civil Engineering with a concentration in Structures from North Carolina State University, an MBA from East Carolina University, and a Lean Six Sigma Green Belt — the process-improvement discipline behind how efficiently Oakline runs today.
Over more than a decade, Cody has engineered for architects, universities, zoos, and military entities. But the work that built Oakline is residential: nothing beats the moment a homeowner goes from anxious to confident because an engineer finally explained their house in plain English — and then stood behind it with a seal.
Across 3,500+ sealed engineering documents, the throughline has never changed: quality engineering that protects your home and saves you money. Built to last, trusted for life.

In the field
Good structural engineering doesn’t happen only at a desk. It happens where the framing is.
Off the clock
Family time with his wife and daughters comes first. After that: podcasts at speeds that alarm passengers, dirt biking, cycling, and a recreational-but-competitive relationship with pickleball. If he calls you back from a trail, that still counts as answering the phone.
