About Daniel Kleven
Daniel Kleven Gelb took a winding path into law that began in the humanities and branched into business. He earned a B.A. in English from Tufts University in 1995, a J.D. from Boston College Law School in 1999 and an MBA in Business and Finance from Boston College in 2001. That combination has informed how he reads cases and how he approaches litigation strategy.
After law school he entered practice in Massachusetts. Early in his career he held a prosecutorial role, serving as an Assistant District Lawyer in 2004 at the Norfolk County District Lawyer's Office. That year in courtrooms and in grand jury rooms shaped his understanding of evidence, procedure and trial dynamics. It also put him on track to spend much of his career on criminal matters.
Gelb has maintained an active membership in several professional organizations. He has belonged to the Massachusetts State Bar since 2004 and to the American Bar Association since 2005. Since 2006 he has been part of the National Association of Criminal Defense Lawyers, the Massachusetts Association of Criminal Defense Lawyers, the Massachusetts Academy of Trial Lawyers and the Boston Bar Association. Those affiliations reflect steady engagement with peers and continuing legal education over two decades.
He is admitted to practice in Massachusetts and New York and is authorized to appear before the United States Court of Appeals for the First Circuit. His education and early prosecutorial experience inform his courtroom work. He handles matters that require motion practice, evidentiary hearings and jury trials. His background in business and finance also allows him to address cases that involve financial records or complex transactional facts.
Clients and colleagues describe Gelb as thorough in preparation and deliberate in the courtroom. He takes a methodical approach to fact development, witness examination and legal research. He has spent much of his career moving between state and federal dockets, balancing trial work with appellate filings when cases require it. He currently concentrates on criminal defense and trial matters in Massachusetts and New York.
