His clients have included Fortune 500 companies, the world’s largest construction contractor, and an international chemical company.

He works closely with clients, developing strategies for defending the case, and ensuring that clients are notified of significant developments and provided with his recommendations as to the best course of action.

Called upon by clients and insurance claims representatives, John regularly gives presentations on various subject matters relating to toxic tort and product liability cases, including those specifically relating to trying asbestos-related mesothelioma cases and cases in which talc products allegedly caused ovarian cancer or mesothelioma. He has co-authored articles on medical-legal issues in the DRI magazine For the Defense and in the Practicing Law Institute’s Toxic Tort Case Essentials.

• Represented a nationally known manufacturer of HVAC and other environmental control systems in a mesothelioma trial in Philadelphia.  After the defense obtained favorable evidentiary rulings and cross-examined all of plaintiffs' witnesses, plaintiff attorney dropped his pretrial settlement demand by 85% and the case settled.
• Represented an oil refinery in a mesothelioma case involving an outside contractor's test engineer.  The court granted the client's motion for summary judgment on the ground that there was no triable issue of fact that the plaintiff was ever exposed to asbestos due to any activities of that premises owner defendant.
• Represented a Fortune 500 telecommunications company in a mesothelioma case involving a former underground construction worker.  Following two hearing on a motion for summary judgment, the dedicated asbestos judge in Alameda County Superior Court granted the motion and entered judgment in favor of the defendant.  The granting of this dispositive motion was one of only two that had been granted by the judge during his several years' long tenure as the assigned asbestos judge.

• Represented a French company that manufactured high voltage electrical cable in a personal injury action in which a lineman claimed an electrical shock that resulted in chronic pain syndrome and the partial loss of the use of an arm.   Following extensive discovery, including depositions in France, the case resolved for an amount which was well below the seven figure settlement demand and several times less than that paid by the co-defendant in the case.
• Represented a manufacturer in a mesothelioma case in which the plaintiffs' attorney requested $26,000,000 in damages in closing argument.  Following a defense verdict, the case received media attention given the extremely high damages sought and the jury's stark rejection of the plaintiffs' claims.
• Represented an internationally known construction contractor and engineering design company in a mesothelioma case.  A motion for summary judgment was brought on behalf of the client and heard just weeks before trial.  The plaintiffs' attorney made a settlement demand of over half a million dollars and threatened to raise it if the defendant proceeded with the motion for summary judgment.  Following oral argument, the judge granted the motion and entered judgment in favor of the moving defendant finding that there was no triable issue of fact that the plaintiff was exposed to asbestos for which the defendant was responsible.
• Represented a nationally known chemical manufacturing company in eight Los Angeles cases in which the plaintiffs alleged a variety of injuries from chemical exposures for which they alleged the defendant was responsible.  Included in those was a case involving a catastrophic injury from a laboratory explosion in which the plaintiff, a Ph.D. chemist, lost one arm up to his elbow and suffered additional serious injuries when he heated and stirred a chemical mixture that included the client's product. After litigating those cases during a three year period, the results were voluntary dismissals in six of those actions, one dismissal following an order granting summary judgment and one nuisance value settlement for $4,500.00 in a confirmed bronchiolitis obliterans ("popcorn lungs") Diacetyl case.   In the catastrophic injury laboratory explosion case, the client received a dismissal with a waiver of costs.
