John Oppenheim
4th District Commissioner, U.S. Air Force Veteran
John Oppenheim was born in San Francisco and after high school, he enlisted in the U.S. Air Force. He served from 1958-1962 as a medic and worked in all departments in the hospital, including the OB Ward. On his first day, his wife delivered their first child. After his discharge he moved back to San Francisco, enrolling at San Francisco State, and earning a BA degree in accounting. He lasted one year sitting at a desk and in 1969 became a salesman in the small computers business. For the next 42 years he held many positions in sales, sales management and had his own company selling computers and software to veterinarians. His last job in 2002 was as director of sales for a software company that had him on an airplane almost every week. It was time to get off the road. He managed to become independent and taught Marketing and Technology at Pepperdine University and Accounting at an adult school.
In 2014 he became a yoga instructor for the VA at Century Villages at Cabrillo, teaching yoga to residents who were enrolled in the drug and alcohol program. This was an eye opener for him. Most of the veterans had PTSD and really benefited from the classes. He taught until Covid hit and did online classes until 2023. While there, he began working with the senior veterans in supportive housing. He became an advocate for all veterans and especially seniors, who are not receiving the care they really need. He interfaced with the case managers and management at CVC and worked to improve the lives of these seniors by offering help with resources and assisting those who work with them with peers. He left at the end of 2023. In January of 2024, he started the Long Beach Area Veterans Collaborative, a nonprofit with a different twist. The mission is to assist those who serve veterans with modern software to help cut down on the time spent doing research for benefits or looking for volunteers. The online resources directory is unique and available to anyone who finds it on the web. This includes veterans and those who care for them. They also advocate for better treatment for all veterans where needed. Their hope is to grow the online directory and partners in the collaborative so that they can spend more time assisting veterans instead of the head-scratching search for a resource because one they had is out of business. The directory is updated every night.
