Commenting on the news of Cliff’s arrival, Paul Sarkozi, Chair of the Firm’s Litigation and Dispute Resolution practice, stated, “Cliff, Steven Paradise and I practiced law together for almost a decade, after which Steven continued to practice with Cliff at V&E. I am thrilled to be working with them again. With the addition of Cliff, along with our most recent lateral partners, Steven and Mark, our Securities Litigation and Regulatory Enforcement practices, in particular, are exceptionally well-prepared to support our clients’ needs as they face a tougher and ever-increasingly regulated environment. Cliff also builds upon our experience and expertise in a wide range of commercial litigation in federal and state courts.”
