Forensic Reconstruction
The average highway accident happens in a matter of seconds, but understanding exactly
how or why the accident happened is a challenging scientific process. In addition to
collecting evidence and data, our engineers analyze all the issues of a case, making sure
our clients understand the underlying causes and countermeasures.  Collision Analysts
reconstruct collisions for our clients to ensure the most effective and comprehensive
investigative report to ensure a successful result.  Our mission is not to be the largest in
the industry, only the most ethical in our products and services.  
All our experts document
our scenes with the use of
precision survey
equipment and 3D
animated software.

Our experts can interview
your witnesses, parties
involved, other experts in
the industry and prepare
detailed documentation to
assist in your case
management.  Our experts
are able to record
interviews in audio and

Our experts are certified in
advanced 3D animations
and Diagrams

Our Experts are able to
