David the Dendrite, also known as David the tree-dweller and David of Thessalonika, is a saint of Thessaloniki. David became a monk at the Monastery of Saints Merkourios and Theodore outside Thessaloniki. Famed for his sound advice, he was hounded by crowds seeking words of wisdom and prayer. Wishing a quiet, contemplative life, David fled to the seclusion of an almond tree, where he lived for three years.
