One of the primary goals in the reconstruction of an accident is to be as accurate as possible with the information available.    Because of our commitment to accuracy during the reconstruction and analysis process, our opinion ultimately may not always be favorable to our client.  You can always count on us to call it like we see it by applying the appropriate science to the available evidence to reach accurate opinions/conclusions.


There is no charge for an initial consultation to discuss your case.  Phone calls and emails related your case are not billed during and after the reconstruction is completed.   

Typically, an hourly fee is charged for any work done.  However, if you need to know the cost of your case before the reconstruction and analysis begins that can be arranged.  This is accomplished by doing a brief review of the case file (All reports, documents, diagrams, photographs, etc.) to better understand the evidence and circumstances of the case.  We can then provide you with the cost upfront to complete the reconstruction and analysis.

If you have a case where you do not want a full reconstruction but a detailed review of the case file only, we can complete a case file review and provide you with an opinion based on the provided information.

Accidents involving Civil and Criminal cases have been handled.  We continue to handle any type of case that you may need assistance with.   
We have worked accidents for both Plaintiff and Defendant.  

Please feel free to call or email to discuss the circumstances of your case or with any questions you may have.
