The family of Marilyn Lee Castaldi announced with sorrow her death from complications of ovarian cancer on January 5, 2017 at White Plains Hospital in New York.

Born in Philadelphia January 24, 1945, Marilyn was an accomplished and well-respected professional in the field of healthcare public relations and communications. A graduate of Syracuse University and the New York University Stern School of Business, she held leadership positions at both global communications agencies and world-class healthcare institutions, including Burson-Marsteller, FleishmanHillard, Hill & Knowlton Strategies, Columbia University Medical Center and New York University Medical Center.

“Marilyn Castaldi was one of the pioneers in the movement to expand the knowledge of pharmaceutical treatments and health care practices to a broader audience of doctors, healthcare professionals, and consumers. Her many colleagues in the healthcare industry are deeply saddened at her loss,” said Harold Burson, Founding Chairman of Burson-Marsteller, a leading global public relations and communications firm.

John Graham, Chairman of FleishmanHillard, said, “Marilyn was a good friend and a terrific colleague for many years. She did a great job for FleishmanHillard in helping build our healthcare capability. Marilyn was a wonderful individual and widely respected by staff and clients alike.”

Marilyn is survived by her brother Bob Castaldi, his wife Anna Paglione, nieces, nephews and cousins, and her partner Philip Hostetter. Marilyn’s husband of 33 years, Howard Singer, died in 2013.
