Brett O'Toole joined the YA Engineering team in 2023. He began working in the accident reconstruction and biomechanics industries in 2011 and has led or participated in over 1,000 accident and/or injury investigations. He has been an ACTAR-certified accident reconstructionist since 2015. Mr. O’Toole earned a Bachelor of Science degree in Biomedical Engineering from Arizona State University. He then went on to obtain a Master of Science degree in Biomedical Engineering from Arizona State University. He has extensive experience applying the principles of biomechanics to vehicular and non-vehicular accidents, both in civil and criminal matters. He has applied his combined accident reconstruction and injury biomechanics knowledge in evaluating a wide range of incidents. This includes cases involving pedestrians, bicycles, motorcycles, heavy vehicles, and other non-standard vehicles. Mr. O’Toole documents vehicles and accident sites with high-quality photographs, laser scans, aerial images, and by retrieval of electronic (EDR) information. Mr. O’Toole is licensed by the FAA to fly drones for commercial purposes. He has also been trained in the use of PC-Crash for accident simulations.
