About Phillips
Ranch
Phillips Ranch, located between Diamond Bar and Chino Hills, is a hillside and master-planned Pomona neighborhood with curving cul-de-sacs and greenbelt trails. The neighborhood’s character concentrates around the Rio Rancho Rd and Village Loop Rd area, where small plazas, coffee counters, and everyday services meet the steady rhythm of commuter traffic. Stucco homes with tile roofs and tidy front yards line winding streets that follow the terrain. The green spine of Phillips Ranch Park and nearby trail links shapes an outdoors-forward routine. Cal Poly Pomona’s cultural calendar and galleries add a campus-adjacent creative note. The 57 and 71 corridors frame the edges, keeping the setting connected while the interior stays residential.
