Dr. Hissey was a member of the American Academy of Pediatrics, where she had served on the Maryland chapter of its Emotional Health Committee, and was a member of the Bradley Pediatrics Society. From 2000 to 2008, she was a member of the University of Maryland Medical Alumni Board.
"She had been one of our very early volunteer doctors," said Charlotte Hawtin, executive director of Joseph Richey Hospice and Dr. Bob's Place.
"Alice was one of our faithful volunteers for many years," said Dr. John W. Payne, a retired Baltimore ophthalmologist who is the hospice's medical director.
"Our volunteer doctors take one day a month to be on call, and in the middle of her busy practice, she was willing to donate one day a month," said Dr. Payne. "She felt so strongly about the mission of the hospice that she became a constant presence. She was someone you could really depend on."
A resident of Columbia since 2007, Dr. Hissey was an avid bridge player.
Her husband of 18 years, William David Hissey, her high school sweetheart who was a senior engineering specialist at the National Security Agency, died in 2005. An earlier 16-year marriage to Dr. Michael Hayes, a Baltimore physician, ended in divorce in 1981.
A memorial service will be held at 1 p.m. Nov. 10 at her church, 14301 Laurel-Bowie Road, Laurel.
Dr. Hissey is survived by two sons, Michael S. Hayes of Los Angeles and Daniel G. Hayes of Sterling, Va.; a daughter, Sharon A. Hayes of Brooklyn, N.Y.; a stepson, Rion Hissey of Johnson City, Tenn.; a stepdaughter, Bonnie Hissey of Denver; two sisters, Cynthia Meininger of Columbia and Betty Reed of Dallas; and four grandchildren.
