Despite 90-degree temperatures, the patients and staff of Clara Maass Medical Center were treated to Christmas in July with a jolly visit from Santa and Mrs. Claus, a tradition that began in 1991. The duo, better known as John and Joyce Wolf, from Kearny, N.J., delivered presents and joy to pediatric patients and newborns in the Maternity unit. Mr. Wolf says that both children and adults appreciate his visits that occur annually in both July and January.
