Who We Are

Riordan & Horgan is one of California's top boutique law firms, specializing in appeals and complex legal matters. Often described as a “lawyer’s law firm,” we bring deep legal knowledge, rigorous advocacy, and personal commitment to even the most difficult cases.

Best known for our record of success in criminal appellate matters, our dedicated team has also prevailed in civil appeals, regularly collaborates with trial teams in high-stakes cases to argue significant matters of law and serves as lead defense counsel in state and federal criminal trials.

While we appear most frequently in California, we also have represented clients in federal and state trial and appellate courts around the country and in the United States Supreme Court.
