William K. Kennedy, P.E.

Senior Mechanical Engineer

Bill received a Bachelor of Science degree in Mechanical Engineering from Wichita State University in 1974.

During Bill’s WSU studies, he was mentored by Professor John Sevart, a testifying engineering expert.  This allowed him access to a diverse set of case studies, which included examination of crash tests, access to all aspects of preparation for testimony, and he was able to witness live expert testimony.  This experience jumpstarted his own engineering practice and it has been the foundation for his national forensic engineering reputation over the last forty years.

In addition to Dr. Sevart’s mentorship, Bill was employed by Professor Kenneth Razak, former Dean of Engineering, WSU, who retired his professorship in order to start his own engineering firm.  During Bill’s senior year at WSU, he began working with Dr. Razak on cases for industry, legal teams, and insurance companies.  During Bill’s employment with Razak Engineering, he earned the responsibility of lead investigator wherein he presented professional engineering opinions and expert testimony in court with regard to  accidents involving all makes and types of vehicles.  He also provided expertise for multiple railroad companies including BNSF, Conrail, Norfolk Southern, Union Pacific, and CSX.

Bill began his private practice in 1987, and continued to provide dependable engineering analysis of vehicle and product accidents.  He has worked throughout the United States over the last twenty-eight years.  Bill has completed over 3000 cases and he has made over 300 appearances in state and federal courts.  This year, Bill joined the Semke Forensic team and offers his expertise as a Senior Mechanical Engineer.
