How Lessem, Newstat & Tooson, LLP Supports Simi Valley Clients

We provide clear, strategic representation for Simi Valley families and individuals in cases involving:

  • Criminal Defense: If you or a loved one has been arrested or is under investigation in Ventura County, our certified criminal law specialist builds strong defenses for misdemeanors and felonies alike. We work quickly to seek dismissals, reductions, or alternatives that protect your future.
  • Mental Health: Recognizing that mental health challenges often intersect with the justice system, we advocate for diversion programs, sanity hearings, and treatment-focused resolutions through Ventura Mental Health Court and beyond. Our compassionate approach prioritizes recovery and stability rather than punishment whenever possible.
  • Personal Injury: Whether you’ve been hurt in a car accident on the 118 Freeway, a slip-and-fall, or a premises liability incident, we fight insurance companies aggressively. We work on a contingency basis for injury cases, so you can focus on healing while we pursue the full compensation you deserve for medical bills, lost wages, and pain and suffering.
  • Civil Rights: We hold law enforcement and institutions accountable for violations such as excessive force, unlawful searches, or institutional sexual harassment. Our civil rights practice protects the dignity and freedoms of Simi Valley residents, ensuring justice when rights are infringed.
