Mammoth Hospital CEO Tom Parker Announces Retirement Plans

Mammoth Lakes, CA — Mammoth Hospital announced today that Chief Executive Officer Tom Parker has informed the Board of Directors of his intention to retire later this year, effective October 2, 2026.

Mr. Parker has served as CEO of Mammoth Hospital for the past seven years, guiding the organization through a period of strategic growth, operational and financial stability, and continued commitment to high-quality patient care for the residents and guests of the Eastern Sierra.

“Last month, my wife, Kristen and I spent a week with our family during the holiday season, which gave us the opportunity to reflect on how we want to spend our time and the shrinking number of years ahead,” says Parker. “As a result of those conversations, we decided that I will retire this year, with a retirement date of October 2, 2026. Between now and then, I remain fully committed to advancing our strategic plans and my individual goals. I am committed to supporting a smooth transition to my successor and maintaining continuity for our patients, staff, and community partners.”

“Leading Mammoth Hospital has been an honor and privilege,” says Parker. “I am deeply grateful to the Board of Directors and to the dedicated clinicians, staff, managers, and executives who deliver compassionate, technically skilled, and highly satisfying care to our patients and community every day. Together, we have strengthened the hospital’s long-term viability and its role as an indispensable healthcare provider for the region.”

According to Board Chair Laurey Carlson, “The Mammoth Hospital Board of Directors expresses its sincere appreciation for Tom’s leadership and years of service and will work closely with him in the coming months to implement a thoughtful and comprehensive succession plan.”
