DA’s Office Secures Restitution for Victim of Dentist’s Illegal Business Practice Aug 25, 2015

OAKLAND, CA – Alameda County District Attorney Nancy E. O’Malley announced today that her office’s Consumer, Environmental and Worker Protection Division has settled a civil law enforcement action against Livermore Dentist Dr Rakhibahen Tejas (Rakhi) Jani, owner of Smiles Unlimited in Livermore, CA.

Dr Jani advertised in the PennySaver weekly flyer delivered to a residential senior facility offering dental implants to new patients at a cost $1,200. Ms Evelyn M., age 80, read the advertisement, went to the dental office, and began the implant process at this agreed upon price. The dental office immediately signed her up for Care Credit, a dental credit business that charged 27% interest without informing her of this fact. Additionally, Dr Jani charged the victim in excess of twice the advertised amount once the lengthy dental procedure had begun.


Ms Evelyn M receives her restitution check from DA Inspector Bermudez.

Doctor Charged with Multiple Counts of Illegal Presciptions Jul 30, 2015

The Alameda County District Attorney’s Office today charged defendant Dr Carol Jessop with four felony counts of unlawful prescription of a controlled substance, two felony counts of providing prescription of a controlled substance to an addicted person, three misdemeanor counts of excessive prescribing and administering of drugs, and one misdemeanor count of possession of a controlled substance.

Dr Carol Jessop had a pain management and palliative care clinic in Oakland. Dr Jessop wrote nearly 5,000 prescriptions for controlled substances in a year period in 2014-2015. She wrote prescriptions for such large quantities of opioids and other dangerous drugs (in some instances more than 10 times the recommended daily maximum dose) that many major pharmacies began to refuse to fill prescriptions written by her. Dr Jessop used to hand out to patients a flyer listing the small pharmacies that would fill her prescriptions.

“The Alameda County District Attorney’s Office is ever vigilant in our investigation and prosecution of health care providers who disregard the law. We as a community place deep trust in those who are trained and licensed to practice medicine, and Dr Jessop failed to abide by the basic standard of care and professionalism we expect of our health care providers,” said District Attorney Nancy O’Malley.

DA O’Malley and DTSC Director Lee Announce Sentencing of Two Defendants for Environmental Crimes Jul 29, 2015

Alameda County District Attorney Nancy E. O’Malley, together with the California Department of Toxic Substances Control (DTSC) Director Barbara A. Lee, announced the sentencing today of Kirk Hayward and Charles Seaton, respectively the former owner and the former vice president of Clearwater Environmental Management, Inc., for felony convictions of conspiracy.

For years, Hayward and Seaton ran the Union City-based company and systematically defrauded Clearwater’s customers, falsified Clearwater customers’ official hazardous waste disposal records, and transported hazardous waste without a license from DTSC.

Defrauded Clearwater customers, including BART, Closure Solutions, Pape Machinery, and Recology, had hired the business to ensure compliance with their legal obligations as generators of hazardous waste, to lawfully transport and dispose of their hazardous waste, and to truly and accurately document disposal in official hazardous waste tracking records called ‘manifests’. However, Clearwater failed to provide customers with all of these environmental services.

“The defendants’ intentional and repeated crimes not only cheated Clearwater’s customers, but wholly undermined the integrity of environmental laws designed to protect public health and the environment,” said District Attorney O’Malley. “We will not tolerate hazardous waste crimes, including the falsification of hazardous waste records. My office greatly appreciates the considerable resources spent and expertise demonstrated by DTSC’s investigators that supported this successful prosecution.”
