STC logoOur logo, representing the joyful connection between people and trees, was created from a wood cut designed by Lower Merion High School art student Joanna Odorisio, and was chosen through a competitive selection process to celebrate Arbor Day 2012. The Lower Merion Shade Tree Commission hopes the use of this logo throughout our website will inspire people to know their trees, understand their value, and strive to protect our community forest.
