The new partners will enhance seven of the firm’s practice areas, including appellate, complex commercial litigation, finance, intellectual property, mergers and acquisitions, real estate and tax.

“These incredibly talented lawyers have made significant contributions to the firm, and they each exhibit the qualities we look for in our partners,” said Scott Wulfe, Managing Partner of V&E. “They have demonstrated a high level of skill in their respective practice areas and a dedication to excellent client service. We look forward to their continued success.”

The following is a list of V&E’s new partners by practice:


Jeremy Marwell is an appellate litigator with experience handling a broad range of civil and criminal matters before the U.S. Supreme Court and numerous federal and state courts. Marwell was recently a key member of the V&E team that secured dismissal, on appeal, of all claims against Avnet, Inc. in False Claims Act litigation involving potentially $1 billion in damages. The groundbreaking decision upended prior understandings of the federal “E-rate program.” He also successfully briefed and argued a case on behalf of the Nevada Commission on Ethics before the en banc Nevada Supreme Court, defending the constitutionality of state conflict-of-interest laws. Marwell graduated from New York University School of Law in 2006 and Yale in 1999. He clerked for Judge Stephen F.

The district court ruled that the former employee was entitled to review KBR’s internal investigation documents, rejecting the company’s assertion of the attorney-client privilege, but the D.C. Circuit reversed and vindicated KBR’s privilege claim. Lollar also successfully defended KBR against the U.S. in a $1.4 billion fraud trial, resulting in a favorable judgment on all contested claims.
