Mary Anne Walling is a member of the firm and a skilled specialist in medical malpractice litigation. Ms. Walling has a unique advantage when it comes to medical matters: She started her career as a registered nurse, an experience that took her to the bedsides of critically ill patients and burn victims.

She also taught nursing skills to students and nursing professionals. And she researched nutritional and metabolic issues in critically ill and burn patients, authoring and co-authoring scholarly chapters and articles on nursing and nutrition. This first-hand knowledge gives Ms. Walling an unparalleled depth of understanding of medical procedures that she has used to her clients’ advantage.

She has helped recover millions of dollars in a series of successful medical malpractice actions since joining the firm in 2001. Ms. Walling, who became a member of the firm in 2011, is based at the firm’s Garden City, N.Y., office.

Verdicts and Settlements:

Ms. Walling has helped her clients to successful settlements in a number of complex medical malpractice cases.

In May 2016, she obtained a settlement for a 67-year-old woman who sought care at a well-respected hospital’s emergency room for severe abdominal pain and constipation. The hospital administered an enema and a potent laxative without doing a necessary C/T scan. The woman was left with a perforated bowel, peritonitis, shock and loss of oxygen to the brain. The error required an emergency laparotomy, creation of a colostomy and left the woman with a permanent cognitive injury.

A month earlier, in April 2016, Ms. Walling settled a case involving the misdiagnosis of a 49-year-old wife and mother of four. A family doctor – who was not a radiologist — misinterpreted a chest x-ray and failed to see that the woman had developed lung cancer. As a result, the woman was left untreated and the cancer advanced to a non-curable Stage 4.
