Throughout the decades, the O'Neill/Moiso/Avery family has remained steadfastly grounded to these words, keeping intact the remaining 23,000 acres of their family ranch known as Rancho Mission Viejo. Today, Rancho Mission Viejo is the last working ranch in Orange County, home to acres of citrus groves, miles of protected creeks and canyons within The Nature Reserve at Rancho Mission Viejo, which provide the idyllic background for multiple mixed-use villages.
