What Makes Graham Your Best Choice for Construction Expert Services?

His twenty-four years administrative experience as a project manager, Director of Operations, and Senior Scheduler enable keen and compelling insights.

Exactitude & Veracity

Getting to the heart of a complex legal matter requires tenacity and smarts. Derek prides himself on the high level of exactitude and articulation of his expert reports and testimony. Indeed, most opposing attorneys seek a settlement without even retaining an expert to try to rebut what they perceive as compelling testimony.

Integrity & Honesty

The integrity of a witness is a critical indicator of how a judge or jury may perceive an expert’s testimony. Many experts lack the educated, confident, and neutral aspects and positions that an expert is expected to evoke. Derek is both a ‘construction’ expert, and an ‘expert’ expert, on which he prides his stellar reputation.
