Stockton, CA — The Board of Directors of Community Medical Centers (CMC) is pleased to announce the appointment of Greg Diederich as the nonprofit’s new Chief Executive Officer. Based in Stockton, CMC is a Federally Qualified Health Center (FQHC) dedicated to improving the health and well-being of low-income and underserved populations.
With a distinguished career in healthcare spanning three decades, Diederich has held key leadership positions, most recently serving as director of the San Joaquin County Health Care Services Agency. In this role, he oversaw a comprehensive agency with a budget exceeding $459 million and approximately 1,470 employees. His leadership was instrumental in achieving national accreditation for the Public Health Department and implementing many innovative programs, including the Drug Medi-Cal Organized Delivery System and a Jail-Based Competency Treatment program.
“We are thrilled to welcome Greg as our new CEO,” said CMC Board President Jasmine Leek Peterson. “His knowledge of the community and his understanding of healthcare delivery systems will be invaluable as we work to meet the needs of our community.”
Diederich also served as interim CEO for SJ Health, an FQHC look-alike, where he managed seven primary healthcare clinics and a mobile clinic, serving over 33,000 patients annually. His tenure as Chair of the San Joaquin County Health Commission saw significant improvements in quality scores, financial stability, and the expansion of services into additional counties.
“I am honored to be chosen for this important role,” said Diederich. “The CMC mission resonates with me because I believe all of us have a responsibility to look out for our neighbors. I welcome the opportunity to work with senior leadership to guide CMC into the future and continue the legacy of caring for the most vulnerable members of our community.”
Before moving to the Central Valley, Diederich graduated with honors from Notre Dame High School in Riverside and earned both a B.A. in Business Economics and an M.A. in Economics from the University of California at Santa Barbara.
Diederich will step into his new role on Nov. 18, following the retirement of Christine Noguera, who has served as CEO since 2014.
