Mike was born and raised in St. Louis, Missouri.  He graduated from Arizona State University cum laude in 1992.  Mike graduated from St. Louis University School of Law in 1995 where he was on the trial advocacy team.

Upon graduation from law school, Mike worked as an Assistant Circuit Attorney in the City of St. Louis from 1995 through 1998.  While working as a prosecutor in the City of St. Louis, Mike tried 15 jury trials in a 3 year span.  He tried over 50 bench trials in the 3 year span and had a term working with the Grand Jury.  Also, Mike began to foster his law enforcement contacts that he maintains today.

After leaving the St. Louis Circuit Attorney’s office in 1998, Mike worked at a civil defense firm in St. Louis.  While working at the civil defense firm, Mike tried numerous jury trials for 4 different insurance companies and was exposed and privy to the insurance defense inter workings.  Today, Mike uses that  knowledge to benefit his clients.

After leaving the insurance defense firm in 2002, Mike was a founding member of the law firm Onder, Shelton, O’Leary & Peterson, LLC.  Mike’s practice included all aspects of personal injury, including products liability, motor vehicle accidents, trucking accidents, dog bite injuries, work place accidents and workers’ compensation injuries.  Mike also assisted in some of the pharmaceutical litigation the firm handled.

Mike has successfully resolved many cases over the years.  In one case, Mike represented the family of a man who was struck on a bridge and obtained a settlement over $6,200,000.00.   In another case, Mike represented the family of a young woman that was killed when the underride bar of an eighteen wheeler failed.  Mike obtained a $3,900,000.00 settlement against the two companies responsible.  In one case, Mike represented the family of a highway worker that was killed by a drunk driver.  Mike obtained a $1,250,000.00 settlement against the drunk driver and obtained a confidential settlement against the bar owner on a dram shop claim for overserving the drunk driver.  In another case, Mike collected $1,219,000 for a client who sustained significant injuries at the hands of a drunk driver.  The drunk drivers’ estate and a bowling alley that overserved the drunk driver were sued. In another case, Mike recovered $1,000,000 for a client that sustained significant personal injuries after she struck a truck that had been improperly parked on a roadway.  In another case, Mike represented the family of a mother that was killed by an out-of-control trash truck and that case was resolved for the policy limits that totaled $939,924.00.  In another case, Mike represented the family of a man who was being transported to the hospital in an ambulance that broke down en route to the hospital and that case settled for a confidential seven figure amount.  In another case, Mike collected $875,000 for a driver of a moped that sustained significant injuries after being struck by a Domino’s delivery driver.  In another case, Mike represented the parent of a teenager that was killed in a drag racing incident on a well-traveled road in South County.

In addition to his full-time duties as a personal injury attorney, Mike has worked as the Brentwood Prosecuting Attorney for 20 years and worked as the Village of Marlborough Prosecuting Attorney for 8 years until the court merged with the St. Louis County Court.
