Our Consultants

My philosophy is that you don’t have to be the one, you just have to know someone. My job as a professional investigator is to help my clients win their cases. To achieve this, I orchestrate a comprehensive field investigation by contracting the talent my clients need to help their case.

This means contracting experts in the corresponding fields that my clients need. From accident scene re-construction professionals, to scuba divers or forensic examiners.

Every case is different, and every one of our teams are built from the ground up to help our clients win. With our team, we are able to re-create accidents using 3D Animation, interview third parties in different languages and more.

The Difference

I never take a case that I personally feel it can’t be won.  That’s what makes Me different. Through a comprehensive consultation, I will be able to understand the ins and outs of your case. This information will help develop a winning strategy, or provide you with referrals to experts who can provide you with the services you need.
