About Us

Our Story

Originally named Renfroe Engineering in 1984 when founded by Dr. David Renfroe, the company name was later changed to The Engineering Institute. Stan Andrews was the Lead Engineer and Accident Reconstructionist and later became a Partner in the company now named Ei Consultants. Dr. Renfroe has now retired and Stan Andrews has owned Ei Consultants since 2012.

One thing that has not changed through the different names and owners is our commitment to accuracy. We offer impartial analysis based on the data we collect and review, bringing years of experience in the field and in the courtroom to each client.

Solutions

We are based in Northwest Arkansas near the cities of Fayetteville, Rogers, Bentonville and Springdale. It’s a beautiful area in the middle of the Ozark Mountains. Our engineers have travel-ready equipment to easily take a flight anywhere in the US to conduct inspections, often on short notice.

Accident Reconstruction and Forensic Analysis rarely has a one size fits all solution for every client. In our opinion, the best solution is the one we build with you. There is never a charge to call and ask us about your case.

Expertise

Using state of the art technology we can convey complex data and key factors in a particular event. Presentations and animations can be useful not only in a courtroom but in many cases during a deposition and often at mediation.

And If we aren't able to help you, we may be able to refer you to someone with the particular expertise you need. Over the years we have worked with many investigators from a wide range of fields.
