Tireless Advocacy for California Employees and Accident Victims

When workplace rights are compromised or a catastrophic accident disrupts your family life, having an aggressive and established legal powerhouse on your side is indispensable. Located at 9327 Fairway View Place in Rancho Cucamonga, California, Mastagni Holstedt, APC delivers resolute legal representation across the Inland Empire, San Bernardino County, Riverside County, and Greater Los Angeles. Founded in 1976, the firm has earned statewide acclaim for championing police officers, firefighters, public sector unions, and private employees. Led locally by seasoned managing attorney Melissa M. Thom, the Rancho Cucamonga office combines deep familiarity with local judicial and administrative procedures with the extensive resources of a premier statewide litigation firm. Whether you need to hire an employment lawyer to fight workplace retaliation or need a lawyer urgently following a major collision, Mastagni Holstedt provides the assertive trial advocacy required to level the playing field against corporate employers and commercial insurance carriers.

Comprehensive Employment and Labor Law Representation

Workplace disputes carry high stakes for your career, earnings, and professional reputation. Serving as dedicated employment and labor lawyers, the firm defends public and private employees through aggressive administrative action and courtroom litigation:

  • Wage and Hour Claims: Enforcing state and federal Fair Labor Standards Act provisions as skilled wage and hour lawyers to recover unpaid overtime, minimum wage shortfalls, missed meal periods, and rest break penalties.

  • Workplace Discrimination and Harassment: Protecting workers rights as committed workplace discrimination lawyers and harassment lawyers against unfair treatment based on race, sex, age, disability, or sexual orientation.

  • Wrongful Termination: Standing up as fearless wrongful termination lawyers for whistleblowers and employees terminated in violation of public policy or employment agreements.

  • Public Safety and Union Advocacy: Defending first responders in internal affairs investigations, disciplinary proceedings, critical incidents, and collective bargaining arbitrations.

Aggressive Personal Injury and Accident Recovery

In addition to workplace representation, the firm functions as skilled accident and injury lawyers fighting for individuals harmed by careless negligence. From busy Inland Empire corridors like Interstate 10 and Interstate 15 to local surface streets, their trial attorneys litigate catastrophic collisions. Operating as dedicated car accident lawyers, truck accident lawyers, and motorcycle accident lawyers, the legal team conducts rapid investigations, gathers crucial forensic evidence, and demands maximum compensation for medical care, lost earning capacity, and pain and suffering.

Workers' Compensation and Disability Claims

On-the-job injuries often create severe financial uncertainty. Acting as experienced workers' compensation lawyers, Mastagni Holstedt assists injured employees through the complexities of the California workers compensation system. The firm ensures injured personnel receive appropriate temporary disability payments, permanent impairment compensation, comprehensive medical treatment, and specialized public safety disability retirement benefits.

Proven Trial Record and Accessible Legal Support

Backed by an AV Preeminent peer review rating and recognition among the Best Law Firms by U.S. News and World Report, Mastagni Holstedt, APC is dedicated to client-centered legal excellence. With bilingual support in English and Spanish, the firm ensures open communication across diverse communities.
