Outstanding Legal Service From

Experienced San Diego Trial Lawyers


Dan Gilleon

For decades, Dan Gilleon has been fighting for his clients with exceptional intensity and passion. His first job was at a law firm that defended insurance companies, where he quickly revealed the “fire in his belly” that has led to many awards and peer recognitions, such as Consumer Attorneys of San Diego’s “Outstanding Trial Lawyer,” many years of “Superlawyer” recognitions, San Diego Magazine’s “Top Lawyer,” Martindale Hubbell’s “AV Preeminent” rating, and many others recognitions listed elsewhere on this website.

What drives Mr. Gilleon is fighting with vigor for his clients, often for the “little guy” being taken advantage of, bullied or not taken seriously. As a result, the Internet and news websites are filled with countless high profile stories of the cases he’s fought and won, often against powerful companies or even dangerous thugs and criminals.

Dan Gilleon was born in Florida but came to California when his father, a Disney “Imagineer,” was promoted to Disney’s mothership. Dan Gilleon graduated from high school in Los Angeles and then joined the US Navy at 17 years old. After his four year enlistment, Mr. Gilleon attended college at UCSD, and then California Western School of Law on an academic scholarship. He graduated from law school with Law Review and cum laude honors.

I have Complex Regional Pain Syndrome (CRPS) and Dan took this difficult personal injury case, which could have gone either way on a decision. From day one Dan started working meticulously and never stopped working until we received just compensation. If you want a smart, honest, non-stop bulldog, there’s only one man I would recommend- Dan Gilleon. I can’t thank him enough.

  • I fully knew what to expect and was informed every step of the way.
