Founder, Weintraub Law Group PC — Securities and M&A Attorney Since 1978

Richard "Rick" Weintraub

Lead counsel on 500+ offerings and 200+ transactions. AV-rated by Martindale-Hubbell. The attorney on every matter.

I'm Richard "Rick" Weintraub, founder of Weintraub Law Group PC and a corporate and securities lawyer admitted to practice in 1978. Over the course of my career, I've served as lead counsel on more than 500 public and private securities offerings and guided clients through more than 200 mergers and acquisitions. The matters on my desk today are ones I've navigated in some form before — and that depth of pattern recognition is what I bring to every engagement.

A Practice Built on Transactions, Not Theory

I came up through Big Law and built this firm around the conviction that sophisticated clients deserve that caliber of counsel without the institutional overhead that comes with it. My hourly rate stays under $1,000 — a deliberate choice, not a limitation. Clients who have retained me have gone up against Cooley, Sheppard Mullin, and Procopio and prevailed.


My practice concentrates on securities law, including Regulation D and crowdfunding offerings, hedge fund formation and investment adviser compliance, FINRA and regulatory matters, and public and private capital raises. On the transactional side, I handle the full spectrum of mergers and acquisitions — from business sales and acquisitions to cross-border deals requiring multi-jurisdictional coordination.


Martindale-Hubbell has rated me AV Preeminent, their highest designation for legal ability and professional ethics — a peer-reviewed credential that has held since the early years of my practice.

Courts and Opposing Counsel Ask Me to Explain Securities Law

My expert witness practice has developed organically from the depth of my transactional record. I've provided testimony and expert opinions on some of the more technically demanding questions in securities litigation — including Rule 144 resale restrictions, Regulation D preemption of state securities law, demand futility in shareholder derivative actions, and the determination of unregistered broker-dealer status.


Retaining counsel — both criminal defense attorneys and civil litigators — engage me when the securities questions in a case require someone who has worked these issues from the transactional side, not just studied them. I work with counsel nationwide on matters where testimony-grade analysis of securities law is required.


If you are defense counsel in an SEC enforcement matter or a litigator who needs a credentialed securities expert, I'd welcome the conversation.
