Expert Witness Testimony in the
Engineering and Construction Fields

Michael Lo Presti Michael Lo Presti, PE, MBA

Welcome. I’m Michael Lo Presti. My mission is to provide you with credible, compelling expert testimony in the construction and engineering fields.

Any litigator worth his or her salt knows this: you either argue the law or you argue the facts.

Argue the law . . .
Magnifying Glass
. . . or argue the facts.

I provide you with the facts. As your fact-finder, I conduct an investigation into the work or issue in contention so you can make the most substantial, robust case possible.

With my specializations in engineering and building design, construction commissioning, inspection and testing, research, materials laboratory analysis, and oversight and representation services, legal professionals increasingly turn to me to give expert testimony. I equip you with hard facts so you can make the strongest case you can.

Pocket Watch

But time is of the essence. Remember, either side in a case can use the same expert witness pool. Make sure you dive in now if you want to retain me, one of the Mid-Atlantic’s foremost engineering and construction authorities.
