Fair. Timely. Thorough.

That is the name of the book our founder, Amy Oppenheimer, wrote in 2003 about conducting investigations, and that is the foundation of what we deliver. Fair, timely, and thorough investigations. Collectively, our team has done thousands of them. Each one is important and gets our undivided attention. Each one delivers insight, integrity and impartiality.

Our Core Values

We value insight – that we can focus a lens on intractable issues and bring them to light so that they can be understood and dealt with openly. We value integrity – every finding is carefully considered and reviewed by at least one other attorney to ensure we are being fair and honest, even when to do so may be unpopular. We value impartiality – we find the facts and then let the facts speak for themselves.
