    Settlement

    Gabe Sassin represented a wife who lost her husband after a major Alabama hospital and its general surgeon failed to timely recognize the signs and symptoms of an esophageal perforation following hernia repair surgery.

  • Confidential
    Settlement

    Gabe Sassin successfully resolved a medical malpractice claim arising from a physician’s failure to recognize the classic signs and symptoms of acute appendicitis. Despite presenting with a clinical picture consistent with appendicitis, the patient was discharged home with an undiagnosed ruptured appendix. The patient returned to the same physician days later in a deteriorated condition, at which point the rupture was finally identified. By then, the delay in diagnosis had allowed the development of an abscess and systemic sepsis. Despite aggressive treatment over the course of three months, the patient ultimately succumbed to overwhelming infection and its complications. The matter was resolved through a confidential pre-suit settlement.

  • Confidential
    Settlement

The resulting bowel rupture triggered septic shock, ultimately causing the patient’s death. The case was resolved through a confidential pre-trial settlement.

  • Confidential
    Settlement

  • Confidential
    Settlement

  • Confidential
    Settlement

    Gabe Sassin successfully resolved a medical malpractice claim against a urologist who failed to recognize and respond to persistently elevated prostate-specific antigen (PSA) levels in his patient.

  • Confidential
    Settlement

The case resolved before trial for a confidential amount.

Fighting for Patients Harmed by the Healthcare System

Despite representing doctors and hospitals for most of his career, Gabe was always drawn to the other side of the courtroom. He felt a persistent pull toward standing up for patients harmed by medical negligence. In 2020, he decided to fully realize that goal and made the shift permanent, dedicating his practice exclusively to representing injury victims.

Medical malpractice is a highly specialized field governed by its own distinct set of rules. Because Gabe spent over a decade defending healthcare providers, he has a rare strategic advantage and unique insight into how each side operates. He understands how doctors, hospitals, and their attorneys think, prepare, and defend. That background allows him to build stronger, more thorough cases for his clients and take a more complete approach to representation.
