About
John J. Hamilton is an Orange County litigation attorney who operates a solo practice and personally handles every client matter. His work includes debt collection defense, business law, employment law, elder abuse, consumer issues, personal injury, criminal law, and traffic law. He prepares legal documents, makes client and case-related calls, and conducts trials himself when needed, giving clients direct attorney involvement from the beginning of a matter through resolution.
John earned a J.D. from William Mitchell College of Law in 1993, a B.S. from the University of Minnesota, and an M.B.A. from Mankato State University in 1981. During law school, he participated in the Moot Court Honors Program and served on a Trial Advocacy Team in national competition, including the ATLA Tournament of Champions at Ohio State University. His education supports his litigation, business, and consumer-focused work.
John brings more than 25 years of business experience from the securities, banking, and insurance industries to his legal practice. Before attending law school, he served as a Senior Vice President of one of the nation’s largest financial institutions. That background gives him practical insight into financial and commercial disputes, particularly matters involving collections, business concerns, consumer issues, and litigation where financial records, contracts, and industry practices may be important.
John J. Hamilton is admitted to the State Bar of California and is also affiliated with The Florida Bar on voluntary inactive status. His professional memberships include the California Bar Association and Consumer Attorneys Association of Los Angeles. He emphasizes hands-on representation and does not employ other attorneys, paralegals, or legal secretaries.
