John Warner designed and fabricated the exterior sculptural elements for the Pine Rest Pediatric Behavioral Health Center in Grand Rapids, Michigan (2025). The installation features a series of kinetic leaf sculptures integrated with sculptural tree trunks along the building’s façade, along with a vibrant outdoor rainbow tree installation. The moving leaves respond to wind and light, bringing motion, color, and a sense of life to the architecture while helping create a welcoming and hopeful environment for children and families entering the center.
