David Stuart Seltzer

David Seltzer is the Managing Partner at Seltzer Mayberg, LLC. With over two decades of experience, he is a nationally recognized criminal defense attorney with a specialized focus on cybercrimes in both state and federal courts. The firm itself was born from David's client-first mentality: in 2013, a client came to him for a referral, and when David later asked how it went, the answer was, "It was not you." David said he could rectify that, and Seltzer Mayberg, LLC was founded.

As a former prosecutor in the Cyber Crimes Unit at the Miami-Dade State Attorney's Office, David has litigated cases from both sides of the aisle, giving him a unique and strategic edge in defense work. He brings an insider's perspective to complex criminal investigations, often involving cutting-edge technology, digital forensics, and high-stakes federal prosecutions.

David is known for relentless advocacy, creative legal strategies, and an unwillingness to accept "no" for an answer. Whether navigating nuanced statutes or redefining what's possible under the law, he is often the attorney clients call when the stakes are highest and the path forward isn't obvious. He believes in figuring out how to put a square peg in a round hole, because that's often what it takes to win.

A 2004 graduate of the University of Miami School of Law, David began his legal career at the Miami-Dade State Attorney's Office, where he gained extensive trial experience early on. He dabbles in Spanish and French and frequently represents clients from diverse international backgrounds. David is admitted to practice in Florida, New York, Colorado, and the District of Columbia, is a member of multiple state and national legal organizations, and is routinely admitted pro hac vice in other jurisdictions.
