He is an unfailing advocate for the rights of the injured and an involved community member, having partnered with both St. Louis Children’s Hospital and Mothers Against Drunk Driving. A great settlement only goes so far; Bill strongly believes that some cases require us all to “pay it forward.” After an especially sad case against a bar for overserving a patron, Bill began sponsoring a local Mothers Against Drunk Driving event. Bill and his client insisted that the bar provide special training to each of its employees on the anniversary of the death of his client’s daughter. When babysitter neglect caused an infant to suffer a head injury, Bill partnered with St. Louis Children’s Hospital and helped sponsor a public service video on child head injuries. In addition to the babysitter’s insurance carrier paying its policy limits, Bill and his client insisted that the babysitter perform 100 hours of community service as part of the civil settlement, which is not often done. Bill and his wife reside in Webster Groves. In his spare time, Bill enjoys playing golf and rooting on his Missouri Tigers, his son’s Northwestern Wildcats, and his daughters’ TCU Horn Frogs.
