About Jon Mower
For over four decades, Jon Richard Mower has been a fierce advocate for his clients in courtrooms across Southern California. Admitted to the California State Bar in December 1976 (Bar #72034), Jon has built a career defined by relentless preparation, commanding courtroom presence, and an unwavering commitment to results.
A graduate of UCLA School of Law, with a Stanford University undergrad in 1972, Jon brings both academic rigor and street-level tenacity to every matter he handles. He doesn't just practice law — he lives it.
Jon's earlier practice at Mower, Koeller, Nebeker, Carlson & Haluck included serious injury and insurance coverage defense. He later helped launch Mower & Carreon, where he represented plaintiffs in employment and commercial insurance disputes. His public case record reflects work on both sides of civil litigation.
