Ryan G. Jacobson

Ryan G. Jacobson joined Knox Ricksen LLP as an Associate in 2010 after serving as a law clerk with the firm. His practice, based in the firm’s Los Angeles office, includes the representation of plaintiffs in “whistleblower” or qui tam actions, toxic torts, products liability, and health care fraud. Primarily, Mr. Jacobson assists in representing firm clients in qui tam actions under California Insurance Code section 1871.7, which is part of the California Insurance Frauds Prevention Act. The qui tam actions are complex and are focused on health care fraud, including actions against doctors, chiropractors and other persons or entities engaged in unfair and fraudulent business practices. The litigation addresses a myriad of illegal business practices, including staging auto accidents, kick-back referral schemes, running and capping, illegal ownership of professional corporations, overbilling of chiropractic and medical services, and billing for chiropractic and medical services not provided.

In 2012, Mr. Jacobson participated in a qui tam action filed by Knox Ricksen LLP on behalf of Allstate Insurance Company against Long Beach chiropractor Daniel H. Dahan, D.C., as well as his company, Progressive Diagnostic Imaging, Inc. A judgment in excess of $7 million dollars in penalties, assessments, attorney’s fees, costs and investigative expenses was imposed against the defendant and is believed to be one of the largest judgments ever under California Insurance Code section 1871.7. (See People of the State of California ex rel. Allstate, et al. v. Daniel H. Dahan, Progressive Diagnostic Imaging, Inc. et al., Los Angeles Superior Court Case No. BC-397695.)
While still in law school, Mr. Jacobson served as a Student Attorney for the San Francisco District Attorney’s Office. There he assisted in the representation of the People of San Francisco in preliminary hearings for felonies as well as misdemeanor trials. Mr. Jacobson gained valuable experience in the fast-paced litigation world, assisting in witness examinations and court conferences, as well as, preparation for trial proceedings.

Mr. Jacobson also participated in a Defense Clinic while in law school. He worked as a Student Attorney for numerous indigent clients in Providence, Rhode Island, assisting them with court appearances, investigation of their case, interviewing witnesses, and preparing for misdemeanor trial proceedings.
Mr. Jacobson credits his work with the District Attorney’s Office, as well as his work with the Defense Clinic, for teaching him the deeper values of justice, fairness, and equality, along with the necessary litigation skills of preparation and strategy, which he continues to bring to his own client advocacy.
