“I have had the pleasure of working with J.M. O’Neill, Inc. since the day I understood my first real estate development project almost 20 years ago. When building in Northern California, I’ve been loyal to J.M. O’Neill Inc. largely because we share the same values with respect to high standards for quality of what we build, integrity and honesty”
