Aaron Osten


Aaron Osten is a versatile and tenacious trial attorney who has dedicated his practice to advocating for employee rights in cases of workplace harassment and whistleblower retaliation, as well as wrongful death, business litigation, and sexual abuse cases. Through his successful jury trials and negotiation skills, Aaron has secured in excess of $75 million for his clients.

Most recently, Aaron obtained a $12.2 million jury verdict for a young woman who suffered a traumatic brain injury after slipping and falling down a concrete flight of stairs at an office building in Hermosa Beach. The young woman had walked over a recently cleaned carpet and tracked carpet-cleaning residue on her shoes, causing her to slip down the stairs. The building owner and carpet cleaning company heavily disputed any wrongdoing and also denied that the Plaintiff suffered any brain injury.

Aaron also recently obtained a $2.1 million jury verdict and $3.2 million in attorney's fees with his Partner Mark Quigley in a whistleblower retaliation case against the County of Los Angeles on behalf of a vascular surgeon, Dr. Timothy Ryan, who blew the whistle on his supervisor who was performing unnecessary surgeries on members of the public for his financial gain in a “kickback” scheme involving the medical device company Medtronic. Aaron also recently obtained a confidential settlement for an accomplished Hollywood actor who was severely injured while shooting a dangerous stunt on a production set.

Aaron’s other results include a $1.7 million settlement on behalf of an accomplished UCSD Professor who was struck by a vehicle while using a marked crosswalk near the UCSD campus, a seven-figure jury verdict, and a confidential settlement on behalf of a cancer research doctor against City of Hope's Beckman Research Institute with a finding by the jury of malice, fraud, and oppression, a $5 million settlement in a legal malpractice case where a lawyer failed to properly advise a hedge fund client of SEC regulations, a $4 million result on behalf of an employee of an independent contractor who suffered paraplegia after being struck by falling machinery at a refinery, a multi-million dollar arbitration award on behalf of a woman who was struck by a defective elevator door and developed Complex Regional Pain Syndrome (CRPS).

Aaron also obtained a $7 million jury verdict at the high-profile sexual harassment and wrongful termination trial involving a whistleblower against celebrity yoga guru Bikram Choudhury. The trial exposed the horrific sexual misconduct of Mr. Choudhury and garnered national attention. Because of this trial, Aaron and the trial team received the "Elite Trial Lawyers" award in Employment Law from the National Law Journal.
