Mr. Tennent has been designing, developing and working with tires for over 20 years. During the Ford/Firestone ATX recall he analyzed and
reported on over 300,000 tires!

He also managed Bridgestone Motorsports and Firestone Racing for several years where he was very poplar among the staff at the IRL, the drivers and team owners such as David Letterman, Chip Ganassi and Roger Penske.

Three years ago, Mr. Tennent retired from Bridgestone/Firestone as one of the engineering managers in charge of Motorcycle, Kart and Government Products (This included passenger, light truck and commercial products) for North America.

He has the distinction of being the only treating physician in Louisiana that has been qualified to testify as an expert in motor vehicle crash biomechanics. He is one of only a handful of doctors to do this nationwide. In addition to his undergraduate and doctorate degrees, Dr. Barczyk has over 300 hours of post doctorate training in biomechanics, occupant kinematics, vehicle dynamics and is an ACTAR Certified Accident Reconatructionist(ACTAR#3183). He also has advanced training tradition Traffic Crash Reconstruction and vehicle dynamics. Dr. Barczyk is Certified by ACTAR in Traffic Crash Reconstruction.(#3183) He also has 150 ours of post graduate study in functional and developmental neurology.

His knowledge and lectures bridge the gap between accident reconstruction, mechanism of injury, human tissue response and pain transmission. He has participated in full scale human volunteer crash testing on multiple occasions with the Spine Research Institute of San Diego (in conjunction with Texas A&M Engineering Department) and the Collision Safety Institute, along with conducting his own crash test seminar in 2016. He is also an Advanced Graduate in Whiplash and Brain Trauma from the Spine Research Institute of San Diego. Dr. Barczyk lectures regularly to physicians, attorneys and judges regarding biomechanics, occupant risk and mechanism of injury.
