Dr. McNair’s passion to make a difference in the lives of children and families impacted by Autism began when he heard the story of a single mother raising a child impacted by this disorder.  After listening and watching this mother thrive, not just survive, in a loving environment and raising her child with autism, he took on the challenge of becoming a student of autism. He told the story of the need and took its fight to the very steps of the state capitol in Jackson, where he was serving as a member of the State Board of Health.   Dr. McNair’s strong sense of family and belief in civic involvement is anchored by a strong religious belief that caring for his fellow man is his calling.

Board Member
Dorothy Dunning

Dorothy Saad-Dunning is the daughter of John and Dorothy Saad who, in addition to founding Saad Healthcare and raising seven children, were life-long and tireless advocates for improving the quality of health care for people on the Gulf Coast. Dorothy was the sixth of their children and the younger of their two daughters. She grew up in Mobile, Alabama, attending public schools in the city. The senior Saads instilled in all their children a sense of responsbility for serving their community and caring for those in need, as well as a strong work ethic.

Dorothy attended the Univeristy of South Alabama, graduating in 1977 with a B.S. She continued her studes at Mobile College (now the University of Mobile), graduating in 1982, with a B.S.N. In 1982, she also received an M.S. from the University of South Alabama.
In 1988, Mrs. Dunning, moved to Mississippi to open and operate Saad Healthcare of Mississippi. She quickly realized that she wanted to remain on the Mississippi Gulf Coast to make a home and raise her family. With a focus on serving the health needs of Mississippi’s
coastal communities, including those of retirees and military personnel, Saad Healthcare of Mississippi has thrived for over 23 years. Mrs. Dunning credits the operating philosophy that was passed down by her parents — “putting patient care first” — for the company’s success:
“This is not just a business for us; it’s our life.” Two years ago, the company moved to a new location in the Bayside Furniture Shopping Center, just off Interstate 110, in D’Iberville. The company now employes almost 100 people in Mississippi, including nurses, physical therapists, occupational therapists, speech therapists, dieticians, and certified nursing assistants, as well as office and store personnel. Mrs. Dunning says, “We have been blessed with a wonderful staff who share our family’s mission.”

Mrs. Dunning is married to Claude Dunning, a professional photographer based in Theodore, Alabama. They have two children, Leland, a senior at the Auburn University, and Cari-Ann, a high school senior who will be attending the University of Mississippi next year.
