  • Why Simmons Hanly Conroy “The best part of my job is meeting with prospective clients,” John said

  • These reasons include its trial team structure, its extensive document libraries, its expertise in dealing with Medicare liens and other archives that expedite the discovery process, just to name a few. “Not many firms have the legal resources dedicated to the mesothelioma and asbestos litigation process we do

  • The six-story building consolidated the firm’s employees from eight buildings around the Madison County area into one central location, for the first time since the firm started
  • Committed to a Cure John formed the firm because after years of working for management, he believed he could provide a higher level of legal care to clients by combining legal expertise with service-minded values
  • That vision expanded when John and the firm made a joint $10.2 million donation to build the Simmons Cancer Institute on the campus of Southern Illinois University in Springfield
  • The cancer institute is a community-based patient care, research, education and outreach program created to improve cancer care for the citizens of Central and Southern Illinois. “It’s just the right thing to do,” John said about his charitable work. “I believe you should always do the right thing, even when you think no one is looking.” Motivated by John’s core belief of giving back to the community, firm employees, through the SHC Employee Committee, have donated more than $1 million to local charities since 2004
  • In addition, the firm has donated more than $20 million to cancer research, through its support of the SHC Meso Committee, the Simmons Mesothelioma Foundation, Miles for Meso 5K races, the Mesothelioma Applied Research Foundation and the Asbestos Disease Awareness Organization. “We’re starting to see hints of progress in the research being done for mesothelioma treatments
  • I know it’s not good for business, but I’m looking forward to the day when the firm no longer handles mesothelioma cases because it has been cured,” John said
