For more than 35 years, Jack has successfully defended hundreds of physicians, nurses, hospitals, and other health care professionals against claims of medical malpractice. He has tried dozens of cases in front of judges and juries throughout Michigan.

Jack has obtained an AV Peer Review Rating from Martindale-Hubbell, and is listed in both Best Lawyers in America and Michigan Super Lawyers under the category for medical malpractice law. He is a member of the American Board of Trial Advocates and a fellow in the American College of Trial Lawyers.

“My clients are health care professionals who have literally dedicated their lives to helping the sick and injured, to bringing new life into the world, and to preserving the health and well-being of those they care for. To be charged with negligently causing harm to a patient is one of the most unsettling events of their professional and personal lives. My goal is to guide my clients through the unfamiliar territory of medical malpractice litigation while preserving their dedication and service to their profession, and also sharing my belief that our legal system does produce justice.”
