  • I’ve been working with JJ Rabinowich of the S4 Group for over a year now. He opened doors for us into the government offices regulating our industry and helped us create relationships with key officials. These relationships have been instrumental in streamlining our procedures and enabling us to minimize obstacles. It’s been a real pleasure working with him.
