Why It Matters

Your Case Needs an Expert
Who's Actually Built Things

Most construction expert witnesses are academics or career consultants. They've studied construction, but they've never run it. Garrett Johnson has. With 20+ years managing complex commercial projects from the ground up, he understands schedules, budgets, and field conditions from the inside out. That real-world experience makes him a more credible construction litigation expert and a more effective construction dispute expert witness for both plaintiff and defense counsel.

Types of Cases

From commercial construction expert witness engagements to residential expert witness testimony, Garrett handles cases across the full project spectrum, for both plaintiff and defense counsel. The same delay analysis that supports a contractor's claim can, in a different dispute, form the basis of an owner's defense. Garrett's testimony is grounded in 20+ years of hands-on construction management, not just courtroom familiarity, which means attorneys on either side get opinions built on real project experience.
