The Trial Lawyer Firm
Other Attorneys Turn To
Wanger Jones Helsley is a full-service California law firm with more than three decades of experience. With offices in Fresno and Sacramento, WJH represents individuals, businesses, and institutions throughout the state across a broad range of disciplines reflecting both the Central Valley economy and the evolving needs of the clients we serve.
WJH is the trial lawyer firm other attorneys turn to when they need litigation or trial assistance. Our record includes a successful U.S. Supreme Court argument by name partner Timothy Jones. The firm is AV Preeminent rated by Martindale-Hubbell, the highest recognition for legal ability and ethical standards.
What has remained constant through decades of growth is our approach to client service. We do not treat clients as files or case numbers. We take the time to understand each business, family, and the practical and personal stakes behind every matter, then build strategy and advocacy from that foundation.
