Our History
Make your handshake
your bond.
The story of Rancho Mission Viejo began in a deal struck with a handshake between fellow Irish immigrants, James Flood and Richard O’Neill, Sr. Since that time, The Ranch's story has continued to evolve with significant development milestones while always remaining true to its ranching roots and values.
