The Diamond Bar City Council thanks all those who have contributed to and dedicated themselves toward the establishment and preservation of the city of Diamond Bar. The council recognizes the efforts of the Diamond Bar Historical Society, including founding members Don Gravdahl, Marilyn Kieffer, Kathleen McCarthy Newe, Arlene Navarro, and Glennon Neubauer, as well as charter members John Isaac, Harriet Isaac, Genevieve Peterson, Rose Repar, Jack Tillery, and Eileen Tillery, and—in particular—former Diamond Bar mayor and historical society founding member and president John Forbing, for the foresight to ensure the preservation of the city’s history and safeguarding our treasures for all these years.
Appreciation also goes to the members of the Diamond Bar History Project, with special recognition to Greg M. Busch for his tenacity and unparalleled detective skills in uncovering our city’s past. Thank you to Bill Bartholomae for his commitment to preserving the Diamond Bar Ranch’s rich history. It is impossible to individually thank all those who have contributed photographs, artifacts, memories, and time throughout the years to preserve the city’s history, but their hard work and dedication have made this book possible.
In addition, we acknowledge the following city staff members: city manager James DeStefano, assistant city manager David Doyle, deputy city manager Ryan McLean, public information manager Marsha Roa, public information coordinator Cecilia Arellano, and city clerk Tommye Cribbins, who, as the city’s first employee, celebrated her 25th anniversary with Diamond Bar in 2014.
We must also recognize the contributions of the early settlers for their fortitude and all the visionaries for their ability to create what most only imagine. Thank you to all the past members of the Capital Corporation, Transamerica Development Company, Transamerica Corporation, Diamond Bar Homeowners Association, Diamond Bar Municipal Advisory Council, Diamond Bar Improvement Association, city council, city managers, commissioners, and community members for laying the foundation from which all has grown.
