Banner Health Announces Sale Agreement for Banner Lassen Medical Center
SUSANVILLE, Calif.– Banner Health announced it has signed an asset purchase agreement to sell Banner Lassen Medical Center to an affiliate of Quorum Health. The transaction is expected to be completed in December 2026, pending required regulatory approvals. The agreement represents both organizations’ commitment to Lassen County and surrounding communities by supporting continued access to local health care under an owner with experience in rural hospital operations in California.
Quorum Health operates 11 hospitals across nine states, including one in California. The organization is committed to strengthening long-term viability and access to care in rural communities. Its local oversight model aligns health care services with community needs and the evolving health care environment.
“We are committed to the future of health care in Lassen County, and that commitment led us to find the right partner to continue delivering great care here in Susanville,” said Margo Karsten, the senior vice president of Banner Health’s Western Division. “An organization with experience operating rural health care within California and a dedication to supporting local teams is the ideal partner to serve this community’s health care needs while preserving access to care close to home.”
Prior to the close of the Banner Lassen transaction, Quorum Health is expected to transition to a nonprofit model and operate as Healthside Partners. As a result of this transition, the affiliate of Quorum Health that is purchasing Banner Lassen Medical Center will be a nonprofit entity at the time the transaction closes. Quorum Health’s existing leadership team, led by CEO Chris Harrison, will remain in place with Healthside Partners.
“We’re honored to have the opportunity to serve the residents of Lassen County, and support continued access to care,” said Chris Harrison, CEO of Quorum Health. “Improving health care in rural Northern California supports our mission to create sustainable health care solutions in more rural and midsized communities.”
Quorum has indicated that it will offer employment to all active employees who satisfy Quorum’s standard hiring criteria at the time of the transition. Patients can schedule and keep appointments as usual, and day-to-day operations will continue without interruption during the transition. The organizations are committed to supporting a smooth transition for patients, employees, and the community.
