Winterbrook Planning

WinterBrook Planning logo


Co-founders Greg Winterowd and Tim Brooks formed Winterbrook after years of collaboration on public projects aimed at the conservation and restoration of natural habitats throughout Oregon. They share a vision of healthy, sustainable communities integrated with a thriving environment. Their community-based planning work promotes compact urban growth with broad public participation, and their signature approach is to work with communities to lay out the green plan first.
