Randy Kent, MS, P.E., Principal

Founder and principal of Kent Engineering, Randy Kent is a Registered Professional Engineer with over 32 years of experience in failure analysis and mechanical engineering forensics. His expertise has been sought in developing the industry-standard ASM Handbook series, International Fatigue Congress publications, with over 100 depositions, trials, and arbitrations to his name. In addition to his work at Kent Engineering, Randy is a professor of materials engineering for upper-level engineering students at the University of Washington, as well an advisor of curriculum development for Haward Technology Middle East. Randy holds a bachelor’s degree and master’s degree in in metallurgical engineering, both from the University of Washington. In his free time, Randy can be found with his wife, kids, and grandkids. He loves all adventures but especially enjoys fishing, hunting, and exploring on his boat. Get to know Randy and read more about his experience here.


Kale Stephenson, PhD, Materials Engineer

Kale is a Materials Engineer with 10 years of research and work experience in failure analysis and materials forensics. Kale holds a PhD in materials science and engineering from the University of Michigan, an MS in materials science and engineering, and a BS in materials science and engineering with a minor in mathematics. Kale's primary expertise is related to metallic materials including fractography, corrosion analysis, and mechanical testing, with a knowledge base extending to iron-, copper-, titanium-, and aluminum-base alloy systems—as well as polymer and composite failure analysis. Kale's fields of experience include consumer electronics, biomedical, oil and gas, automotive, heavy machinery, and water delivery systems (piping and plumbing).


Mike York, P.E., MS, Materials Engineer

Mike is a Senior Engineer with over 39 years in the field. He received his BS in metallurgical engineering and his master’s degree in material science, both from Oregon State University. He’s also a Registered Professional Engineer in the state of Oregon. Mike focuses his consulting in failure analysis of materials and mechanical systems; materials testing and evaluation; weld testing and procedures; examination of fractures, components, and surfaces; inspection of various accident types, including vehicles for motor vehicle accident reconstruction, performing speed, time, distance, and reaction time calculations for reconstruction. Mike is also experienced in fire origin and cause analysis. He specializes in mechanical testing of materials, imaging of airbag control modules using CDR/Bosch instrumentation, fracture analysis, and slip resistance measurements of walking surfaces using variable incidence tribometer (VIT). In his career, Mike has provided expert testimony in over 100 trials and depositions. When he’s not working, Mike can be found spending time with his wife, daughter, and dog, Parker. Beyond engineering, Mike is a horse expert, and enjoys boarding and showing horses in regional and national competitions.
