About Mr. Tremblay

Mr. Tremblay has over 17 years of experience as a mechanical engineer with comprehensive expertise in a variety of fields. As a forensic engineer, Mr. Tremblay has developed models to simulate vehicular dynamics of commercial tractor trailers in adverse weather conditions and has utilized complex three-dimensional computer analyses to simulate vehicle motion before, during, and after an accident. Mr. Tremblay post-processes vehicle motions to develop scientifically accurate forensic analyses for use in conveying motor vehicle accident events and effects. Mr. Tremblay investigates product liability claims ranging from large scale industrial machinery accidents to consumer oriented products for cause and origin of component failures. He continues to research vehicular dynamics and machine design and enjoys presenting new technologies and methods to insurance professionals, attorneys, business owners, and fellow engineers.

Mr. Tremblay's Professional Background

Mr. Tremblay comes from a diverse professional background with experience in engineering, design, and management. Outside of forensic engineering, he has worked within the realm of product development for a company focusing on robotics and automation for the pharmaceutical, life science, and drug discovery industries. His experience in new product development includes research and development (R&D) of new products and product categories, machine design, computer aided design, computer programming, engineering testing, failure modes and effects analysis (FMEA), systems engineering, as well as manufacturing engineering. Mr. Tremblay has extensive experience in manufacturing processes, including material removal methods such as multi-axis computer numerical control (CNC) machining, CNC water-jet cutting, electrical discharge machining (EDM), plasma cutting, and welding.

During his project management experience, Mr. Tremblay was responsible for the successful commissioning of multi-million dollar test integrations deployed within medical device manufacturing facilities and national bio-pharmaceutical companies. His involvement with these projects was all encompassing, and included engineering design, generation of functional specification documents, functional requirements specifications, as well as functional testing and validation of the subject system after installation and deployment was completed.


Off-Road and Snow Sports Accident Reconstruction and Winter Conditions

Mr. Tremblay has been an avid mountain biker for over 20 years. During his collegiate years, Mr. Tremblay was involved in racing of bicycles at a professional level. This experience has proven valuable in analyzing the unique dynamics of off-road riding as well as influences on bicyclist-based perception and reaction, as well as rider dynamics. Mr. Tremblay is an avid snowmobile enthusiast and regularly participates in off-trail deep snow mountain riding. Additionally, Mr. Tremblay is an avid backcountry skier and snowboarder and has experience in leading groups on multiple-day off-grid excursions into the backcountry during winter conditions. As a part of this role, he has been trained in backcountry rescue and recovery techniques within deep snow and unstable conditions. He has been a snow sports enthusiast since his formative years, and has first-hand familiarity with all major ski areas within Colorado. This experience has proven valuable in reconstructing accidents in these adverse conditions, and has aided in application of advanced methods within the area of forensic engineering.

In his free time, Mr. Tremblay has volunteered for agencies such as Habitat for Humanity for their low-income house building projects and is an active singletrack trail building volunteer for the United States Forest Service. He also enjoys spending time with his wife, son, and daughter in the beautiful mountains of Colorado. Mr. Tremblay is a Colorado native.
