The staff at Introtech have over two hundred years of combined investigative and reconstruction experience in military and law enforcement agencies. We apply this vast on-scene expericence along with our specialized traiining and education from a wide variety of educational institutions to reconstruct transportation casualties.

Many experts in crash reconstruction are single person operations with limited time and resources. Introtech has a full staff of support personnel to assist and complement our investigative staff. During normal business hours your call will be answered by a human being and not a voice mail system.  We provide 24 hour access to our services through our on duty reconstructionist. We understand how frustrating it can be to need administrative help and only get a voice mail message.  If our lines are busy and your call is answered by our message system, we will call you back quickly.  Our investigative and support staff work together in synergy to provide the most professional and effective crash reconstruction possible.


Founded in 1989, Introtech’s team of investigators, scientists and reconstructionists have over 200 years of combined on-scene experience in investigating all manner of transportation casualties.


All of the Introtech reconstructionists hold or in the process of earning the prestigious ACTAR (Accreditation Commission for Traffic Accident Reconstruction) accreditation. ACTAR is an internationally recognized commission with approximately 950 ACTAR Accredited Reconstructionists the United States, Canada, Australia, Singapore and the United Arab Emirates. These Accredited Reconstructionists are engineers, physicists, police officers, consultants, former police officers and those of other backgrounds working in the profession.
