JDEA offers a limited case review for a very reasonable price.

Litigation can be costly and we understand that. Clients should have an expectation that the expert they consult truly does have their best interest in mind. This includes cost management. Using client supplied reports, facts, photos and data, a case assessment can be done to provide clients with an understanding of the dynamics of the collision as well as the strengths and weaknesses of the case. An honest and objective opinion will be provided verbally or as a written synopsis.
