Significant Representative Matters

Received a defense verdict in less than one hour in a dental malpractice case involving allegations of the use of excessive force and the failure to obtain the patient’s informed consent after a patient’s jaw was fractured during a molar extraction. It was admitted that jaw fracture was a known risk of the extraction, but that the dentist did not warn the patient of this risk. It was also conceded that the dentist caused the fracture. Lastly, the patient’s damages were not contested, which included the pain and suffering associated with the fracture and permanent numbness to the lower jaw. On cross-examination of the patient’s seasoned expert, he was confronted with prior inconsistent testimony regarding his experience in extracting molars and his opinion that all risks of a procedure need to be shared with the patient. Further, the expert agreed with the defense’s argument that the risk of jaw fracture of an erupted right lower molar was less than .0009% and the patient had a better chance of dying from complications associated with the extraction than suffering a fracture. The jury was persuaded by the defense’s arguments early in the case due to the thorough cross-examination of the patient’s expert. 

Received defense verdict in a wrongful death and survival medical malpractice arbitration involving a single mother in her twenties from toxic shock syndrome. The plaintiff was admitted to a hospital facility with a provisional diagnosis of anaphylaxis secondary to a medication allergy. The patient deteriorated under the supervision of a nurse practitioner while on a telemetry unit and was eventually transferred to the intensive care unit. The patient succumbed to her condition several days later. There was a substantial future economic damage and pain and suffering component to the case given the plaintiff’s young age, rapid decline and extent of necrosis (face, upper and lower extremities).

Obtained a defense verdict in a nursing negligence claim. The plaintiff alleged to have suffered a fall in a hospital bathroom three days post-operatively that re-injured his surgically repaired knees. The nurses denied the patient fell to the ground and testified, consistent with their charting, that the patient lost balance in the bathroom and sat on a commode. There was a significant economic damage claim in that the plaintiff was a young restaurant owner who suffered two distinct orthopedic injuries that required multiple surgeries and additional future care. The jury returned a defense verdict 50 minutes after deliberation began, finding that the nurses were not negligent.

Obtained a defense verdict in a medical malpractice trial involving a middle-aged mother of two who was allegedly left a quadraparetic and wheelchair-bound as a result of a physician’s failure to timely diagnose and treat an infectious process of the cranial nerves and cerebellum. The plaintiff argued that as a result of the alleged negligence, she needed home health care for the rest of her life and submitted expert testimony arguing for the recovery of boardable future medical expenses totaling $4 million and past and future pain and suffering. The last settlement demand was $2 million.  No settlement offers were made prior to or during trial.
