About me

The secret to success for Marshall P. Whalley has been his widely varied interests and seemingly boundless energy to pursue them. Having immersed himself in such fields as mechanics, physics, physiology, education, consumer protection and medicine, Mr. Whalley has acquired a wealth of knowledge directly applicable to the investigation and litigation of personal injury cases.

Mr. Whalley's father attended M.I.T., earning two engineering degrees and going on to design tanks for the government. His mother was a nurse educator with a Bachelor of Science and a Master's degree. Growing up near the Motor City, Mr. Whalley spent long hours building and racing cars, and many summers working on his grandfather's farm.

Mr. Whalley attended the University of Michigan in Ann Arbor where he studied physics and psychology, earning his B.S. in 1980. His graduate work there in physics at the Kresge Medical Hearing Research Institute involved training lizards to respond to acoustic stimuli. His other pursuits included designing and implementing pilot programs at the Milan Federal Correctional Institute and the Maxey Boys Correctional Institute, allowing inmates to obtain GED certificates.

Mr. Whalley also worked in the Consumer Protection Division of the Washtenaw County Prosecutor's office, where he mediated consumer complaints, securing the largest consumer settlement to date in the Division's history. At the same time, he worked for a tenant's rights group helping educate renters regarding their rights vis a vis large corporate landlords. During the summer months, Mr. Whalley continued to attend class at Ann Arbor, but also worked 40 to 50 hours per week on the assembly line in Detroit for both Chrysler and General Motors. On the line, he ran presses, welded wheels, performed manual assembly and body work, and painted cars.

Thereafter, Mr. Whalley received a scholarship to Valparaiso University School of Law. He continued to work on cars and drag raced to help pay college expenses. He then took a job clerking for a well-respected personal injury firm doing medical research, writing and investigating. He became a lawyer at the firm, then partner, using his background in physics and medicine to facilitate settlements of the two largest brain-damaged baby cases in Florida's history. Mr. Whalley's background in physics allowed him to employ a waveform analysis of fetal monitor strips to prove when a critical tocolytic drug had been stopped.

Over the past 30 years, Mr. Whalley's myriad interests have helped him to be an effective advocate for his clients. Designing, building, racing and repairing all types of vehicles, Mr. Whalley developed insight into crash dynamics that few lawyers have. His training in physics and medicine has provided a unique perspective on the causes of complicated crashes and their medical consequences. Marshall P. Whalley has used his unique background to prove-up millions of dollars in valid claims that might otherwise have been lost.
