The Victoria and Peter Chow Hope Tree

A symbol of hope, the 13-foot-tall steel and bronze Hope Tree sculpture is central to the Martin-O’Neil Cancer Center. Adorned with delicate copper leaves, the tree features 48 symbols of hope from around the world, each which were carefully chosen by employees of St. Helena Hospital. Patients, families and their friends are encouraged to include their own personal message of hope.
