Acclaimed Litigators For
Catastrophic Injuries

Sidney Stillerman Royer

  • Shareholder

Sidney Royer started out as a psychiatric social worker, and worked for several years in that capacity in a number of different hospitals. Her familiarity with hospital administration and medical procedures made her particularly well qualified to deal with the intricacies of medical and psychiatric malpractice cases when she turned to the law in 1983. Since then, she has helped scores of clients, not only those injured through medical neglect or abuse, but also victims of violent crime, and people who have been seriously injured in a variety of circumstances. In each of these cases, her background has allowed to better understand the trauma faced by those who have been seriously injured, and to forcefully advocate on their behalf.
