San Diego Securities & M&A Attorney — Big Law Experience, Boutique Rates
Founders, fund managers, and business owners throughout San Diego County retain Weintraub Law Group for securities offerings, M&A transactions, and expert witness matters that demand senior-level judgment — not a generalist learning on the job.
Weintraub Law Group PC is based in Scripps Ranch, San Diego, where Rick Weintraub has practiced securities and corporate law since 1978. The firm has served as lead counsel on more than 500 public and private securities offerings and closed more than 200 mergers and acquisitions — a track record built largely on relationships with San Diego founders, fund sponsors, and business owners who came back for their second and third transactions.
If you are searching for a securities and M&A attorney near you in San Diego, you are likely facing one of three situations: raising capital for a company you are building here, buying or selling a San Diego-based business, or managing a regulatory matter that requires local presence and national-caliber experience. We handle all three.
Why San Diego Companies Choose Local Counsel
San Diego's business community — biotech, life sciences, technology, defense, and a deep bench of founder-led companies — generates a steady flow of capital raises, business sales, and fund formations that require securities counsel familiar with both the regulatory framework and the local market. A national firm headquartered elsewhere will not have that local context. A generalist San Diego business attorney will not have the securities and M&A depth.
Weintraub Law Group sits at that intersection: a San Diego-based firm with the offering and deal volume of a far larger practice.
We work directly with:
- Serial entrepreneurs and startup founders raising capital in San Diego's venture and angel ecosystem

Meet With Senior Counsel in Scripps Ranch

If you prefer to work with counsel you can meet in person, our Scripps Ranch office is built for that kind of direct relationship.
Frequently Asked Questions
Does Weintraub Law Group only handle matters in San Diego?
No. While our office is based in Scripps Ranch, San Diego, and a significant share of our clients are local, our securities, M&A, and expert witness practice extends throughout California — including Los Angeles — and nationwide. San Diego clients benefit from local presence; clients elsewhere benefit from the same depth of experience.
What makes a San Diego securities attorney different from a general business lawyer?
Securities law is a specialized, heavily regulated practice area governed by federal statutes, SEC rules, and state blue sky requirements. A general business attorney may handle contracts and entity formation competently but lack the offering-specific experience to structure a compliant capital raise or fund. Rick Weintraub has served as lead counsel on more than 500 securities offerings — a volume that few San Diego attorneys, generalist or specialist, can match.
I'm selling a San Diego business — do I need an M&A attorney, or can my regular business lawyer handle it?
A business sale involves purchase agreement negotiation, representations and warranties, indemnification provisions, and often securities or regulatory issues that a general practice attorney may not handle regularly. Weintraub Law Group has closed more than 200 M&A transactions and can identify the deal terms and risks that an infrequent dealmaker is more likely to miss.
