Garrick F. Mitchell

Transportation Practice Leader / P.E., ACTAR / Denver


Mr. Mitchell graduated magna cum laude from Rice University with a B.S. degree in Mechanical Engineering in 1993 and a M.S. degree in 1995. Since joining Rimkus in 2000, Mr. Mitchell has performed over 1,000 forensic investigations, including vehicle accident reconstructions, mechanical failure investigations, and consumer product analyses.

Mr. Mitchell has reconstructed hundreds of accidents involving all manner of vehicles as well as bicycles and pedestrians. He mechanically inspects vehicles, performs site inspections, and analyzes pertinent data including police reports, photographs, videos, driver/witness statements, weather data, cargo securement, and traffic signal data. He is trained and experienced in reconstruction technologies including digital site mapping and the collection and analysis of event data recorder information from cars and trucks and electronic data from bicycles.

In addition to being a licensed Professional Engineer and Accident Reconstructionist with a significant expert testimony record, Mr. Mitchell has been a competitive amateur bicycle racer since 1989 and has ridden over 150,000 miles to date. Mr. Mitchell has raced extensively in all road disciplines (road race, criterium, and individual and team time trial), on the track (velodrome), and in cyclocross events. His racing results include two Category 3 State Criterium Championship victories in Texas (1999 and 2000). This combination of engineering and racing experience makes him uniquely qualified to analyze accidents and mechanical failures involving bicycles and to opine on a cyclist’s standard of care and whether it was met in an accident situation.

From tens of thousands of miles of training on public roads, Mr. Mitchell has experienced first-hand how bicycles and motor vehicles interact and, sometimes, come into conflict. Mr. Mitchell has reconstructed accidents between bicycles and passenger cars, commercial vehicles, pedestrians, other cyclists, and even forklifts. Off-pavement and on paths and trails closed to motor traffic, Mr. Mitchell is intimately familiar with the potential conflicts between trail users of all categories.

Mr. Mitchell is also an expert on bicycle design, fabrication, and service, takes pride in servicing his own bicycles, and has examined multiple mechanical failures, including frames, forks, wheels, and brakes. He has served as an expert witness in patent-infringement lawsuits involving bicycle-related parts. Mr. Mitchell is qualified to deliver deposition and trial testimony of his findings and has testified in federal and state courts.
