About HASC

Who We Are

The Hospital Association of Southern California (HASC), founded in 1923, is a not-for-profit 501(c)(6) regional trade association. HASC is dedicated to effectively advancing the interests of hospitals in Los Angeles, Orange, Riverside, San Bernardino, Santa Barbara and Ventura counties. We comprise 176 member hospitals and 31 health systems, plus numerous related professional associations and associate members. All have a common goal: to improve the operating environment for hospitals and the health status of the communities they serve. 

Working in partnership with the California Hospital Association (CHA), HASC provides leadership at the local, state and federal levels on legislation, budget concerns and regulatory issues. We work with county boards of supervisors, chambers of commerce, local health departments and other agencies to assure the hospital’s voice is heard.

We serve our members through several unique organizations:

  • HASC — A historically strong hospital trade association that serves the political, economic and educational needs of hospitals.
  • AllHealth, Inc. — A for-profit, HASC-owned subsidiary providing specialized fee-for-service products to help hospitals improve operations.
  • Communities Lifting Communities (CLC) — A 501(c)(3) nonprofit affiliate of HASC that focuses on reducing health disparities and improving community health in HASC’s six-county region.
  • National Health Foundation (NHF) — A not-for-profit applied research organization affiliated with HASC and dedicated to improving health care delivery and access.


Our mission is to lead, represent and serve hospitals and their related organizations, working collaboratively with our members and other stakeholders to improve health and health care in the communities we serve.


Our vision is for all member hospitals to consistently and uniformly provide safe, high-quality, cost-effective and culturally appropriate person-centered health care services.

In a changing health care environment, hospitals need assertive representation. Through partnerships with CHA and hospitals like yours, we work to influence the future of health care in a way that best
represents your interests, your patients’ needs and the communities you serve. Together, we create visionary change that no hospital can achieve alone. HASC helps to:

  • Improve quality and patient safety
  • Support hospital transition to value-based purchasing and health care reform
  • Promote appropriate reimbursement from Medicare and Medi-Cal
  • Preserve the safety net, trauma systems and access to care
  • Provide education, funding and promotion of disaster and pandemic preparedness
  • Initiate long-range solutions to the hospital workforce shortage


HASC brings extensive expertise to your hospital. We scan the environment, help decipher what’s important and deliver in-depth guidance on issues that most impact you. We keep you ahead of what’s happening in the industry and deliver representation you can count on through:

  • Local representation—regional staff represent your needs with expert knowledge of community issues and strong relationships with local representatives and key decision makers.
  • Media relations—expert representation in the media builds support for hospital issues and keeps the public informed.
  • Member seminars, workshops and conferences—in-depth information on topics such as implementing health care reform, physician/hospital relations, quality improvement and financial management from industry experts.


Working with the association strengthens your hospital’s performance with services from professionals who know your operational needs. By turning data into knowledge and providing innovative ways to boost efficiencies, HASC helps you benchmark the quality of your services, improve business operations and maximize reimbursements.
