M & A transaction attorneys with offices in San Diego, CA and Chicago, IL.

We work with clients in a broad range of industries when they’re selling their business or looking to grow by acquiring another business.  

Business owners only get one shot at getting an M&A deal or a purchase or sale of a business done right.

M&A transactions are time-sensitive, consequential, and complex. Most business owners will go through one or possibly two transactions in a career. We help guide you and achieve your objectives in the biggest deal your business will have.

Our Areas of Expertise

Corporate Transactional Law

From corporate formation to operations and restructuring to IP and trade secret law, we take care of all the details and do it efficiently and effectively.

Mergers and Acquisitions

Our team quarterbacks the transaction from start to finish, providing expert legal guidance and sourcing any external resources you may need to achieve your objectives.

Securities Law

Whether your company is making a private offering or preparing to go public, the securities law rules and regulations are complex and seemingly never-ending. We work with you to handle the legal compliance, so you can focus on your business.
