PHS Tree Tenders is at the forefront of the urban tree movement across the country. PHS works to train hundreds of new Tree Tenders every year. They go on to form groups in their neighborhoods that transform the health and well-being of their communities by rallying neighbors to plant and care for trees. See how you can get involved in planting trees in your neighborhood today.
