- $285.9 million spent. Sonora Community Hospital, dba Adventist Health Sonora (AHSR), provides quality medical healthcare regardless of race, creed, sex, national origin, handicap, age, or ability to pay.

We are inspired by the healing ministry, as represented by the life of Jesus Christ, and believe we are called to live out our mission intentionally in the communities we serve. In the small towns, suburbs, and inner cities we serve, we continue our journey to provide quality healthcare until every person made in God's image has experienced the best health today, hope for tomorrow, and God's love that endures forever.As part of AHSR's ongoing commitment to creating sustainable solutions to rural healthcare challenges, Adventist Health Sonora is investing in education and workforce development programs that train, retain, and empower local healthcare professionals. This summer, the Family Medicine Residency Rural Training Track welcomed its inaugural class of four resident physicians. Over the next two years, these physicians will complete hands-on residency training and deliver primary care services at the Family Medicine Residency Medical Office in Sonora. As an accredited graduate medical education program, the residency emphasizes the unique healthcare needs of rural communities. A new cohort of four resident physicians will join the program annually. Also launching this fall is the Pacific Union College (PUC) Associate of Science in Nursing program at Adventist Health Sonora, welcoming its first class of 20 students. This hybrid program combines online instruction from PUC faculty with in-person clinical rotations at Adventist Health Sonora, allowing students to pursue nursing careers while staying connected to their local community.These programs are building a pipeline of homegrown healthcare professionals so we can serve the needs of our community, now and into the future, said Greg McCulloch, president of Adventist Health Sonora. One of our core beliefs as an organization is that our rural community deserves accessible, quality healthcare. Programs like these are vital for rural communities, where residents often face significant barriers to care due to chronic shortages of providers and nurses. The Health Resources and Services Administration (HRSA) has officially designated Tuolumne County as a Medically Underserved Area because of a shortage of primary care health services. These new initiatives build on Adventist Health Sonoras growing portfolio of workforce development programs. The certified nursing assistant (CNA) and medical assistant (MA) training programs have already made a measurable impact, providing entry-level pathways into healthcare. Since 2022, 32 CNAs have graduated from the program, and 10 MAs completed the first MA cohort earlier this year. A new MA cohort is set to begin this fall.We see our workforce training programs as a win-win, said Tyler Newton, operations and service line executive at Adventist H
