Elder Abuse

At Stalwart Law Group we are passionate about protecting the rights of elders. We have successfully litigated and tried elder abuse cases on behalf of victims of neglect and abuse in nursing homes, assisted living communities and hospitals throughout California.


Our attorneys fight to keep children safe and hold schools accountable when harm has occurred.

Commercial Litigation

Our attorneys regularly are called upon to litigate all types of commercial litigation matters, including breaches of contract, partnership disputes, real estate disputes, fraud claims, unfair competition claims, and others.

Intellectual Property

Stalwart Law Group has an active intellectual property practice. Our lawyers have litigated numerous copyright, trademark, trade dress, and similar intellectual property claims.

Legal Malpractice

We have litigated dozens of legal malpractice matters in virtually every area of the law, from tax to real estate; simple conflicts of interest to civil RICO.

Who We Are

Results driven. Client focused. Unwavering dedication.


All of our clients can expect the same peak level of personal care and attention, which we feel is a key element in our formula for success. Our diverse team of plaintiff lawyers hail from elite law schools and have honed their litigation skills at internationally renowned firms representing Stalwart’s biggest adversaries, the insurance companies and healthcare providers.

What does this mean for you?

  • We have recovered over $150 million dollars in the last two years and continue to add to these impressive victories that change the lives of our clients for the better.
  • Our prior experience with fighting and winning for “the other guys” means we know how they operate and can use their own methodology to your advantage. Working with fierce litigators who are at the top of their game, bringing their years of applied experience to your case.
  • We fiercely believe in each case we take. This passion meets professionalism and experience in the courtroom, and this powerhouse combination is what drives our results.
  • Our diverse, multi-cultural team of attorneys includes strong, female and Latino litigators. These unique perspectives help us forge meaningful connections where it matters and where gender or language adds to the complexity of a case.
