Jonathan Fong, MBA
Marin Treatment Center
Jonathan Fong has been with Marin Treatment Center since 2012 and has over 20 years of experience developing and managing non-profit and for-profit healthcare agencies, and owns his own health agency. Jonathan has spent his professional career working in substance dependence and mental health industries and has particular expertise in strategic leadership, healthcare information systems, performance and quality management and business analytics.
Jonathan is passionate about developing and managing high quality and affordable healthcare agencies and deeply believes that mental health and substance use treatment services should be available to everyone, despite the individual’s economic situation. His vision is to develop Marin Treatment Center into a full service behavioral health provider that can offer a spectrum of mental health and substance use treatment services to low and middle income Marin County residents.
Since his arrival Jonathan has introduced electronic health systems, broadened Marin Treatment Center’s services by adding drug free programs and mental health programs, and has negotiated private health insurance contracts with insurers such as Kaiser, Anthem Blue Cross, Aetna, and Veterans Administration.
