Recently, I had the distinct pleasure of working with Johnny on a very complicated CA psyche exposure claim that appeared to be headed for a 100% award (Labor Code section 4662); and the applicable lifetime exposure. Using considerable persistence, patience, creativity and legal expertise, Johnny was able to resolve this most complicated claim at a considerable savings discount via a Compromise and Release, with an approved zero dollar MSA. Throughout the litigation process, Johnny kept me informed and up to date. I was extremely pleased with Johnny’s performance and would gladly recommend his legal services to any prospective clients.
