For Attorneys

An expert who has run the tests himself — thousands of times.

Many experts interpret test reports. Jimmy Cruz spent his career producing them inside an accredited fenestration test laboratory (FTL), running the exact ASTM and AAMA protocols at issue in construction-defect litigation. That first-hand laboratory and field experience means opinions that hold up under cross-examination: what the standard requires, how the test must be run, and what the results do — and don't — prove.
