Our People

These days it seems almost everyone is an "expert." Our experts are established professionals with many years of experience on actual job sites. 

At many of the larger firms specializing in construction defect litigation, the designated expert is typically a figurehead - rarely on site, leaving the bulk of the work to be handled by project managers. We take a WYSIWYG approach at cdP: What you see is what you get.
