  • “I wanted to take this opportunity to give a recommendation to you all for my friend, Ron Chapman.  We have been working together for the last two years on a very difficult healthcare fraud and drug diversion case in Federal Court.  We have sentencing tomorrow.  The level of knowledge and expertise that Ron has in this area of the law is unmatched.  There is no way that I could have imagined having effectively handled this case without him. Prosecutions are increasing in healthcare fraud cases both on the federal and state level.  The law and concepts are very complex, and difficult to get a hold on, If you haven’t handled one of these cases before. I would HIGHLY recommend considering referring these cases to Ron, or bringing him on as co-counsel.”
  • “I found Ron while looking for an attorney to help one of my physician patients. In working with him, I instead found an intense, sometimes brutally honest, no-holds-barred attorney I wanted to put in a head-lock, or hug like my younger brother. Throughout this time, I found Ron to possess qualities only a handful of my closest friends of 20+ yrs do: The ability tell the truth as they see it, meticulous attention to detail, calling each other to the carpet, the utmost in personal integrity and ethics at all levels of personal and professional matters, and a sense of humor. However, what makes him unique is his knowledge of pain management and responsible opioid prescribing that exceeds the majority of practicing physicians. It’s uncanny: I witnessed it firsthand in a lecture we gave recently, along with his ability to master the audience. Solid. One of the best.”
