UCHealth Greeley Hospital president to retire
GREELEY — Marilyn Schock, who has been president of UCHealth Greeley Hospital since it opened in July 2019, announced this week that she will retire in February after 40 years of working in health care in Northern Colorado.
Schock, selected as one of BizWest’s 50 Most Influential Business Leaders in 2022, 2023 and 2024, among its Notable Women in Health Care in 2021 and among its Women of Distinction in 2010, was first hired by UCHealth in 2014 as chief operating officer at Medical Center of the Rockies in Loveland and Poudre Valley Hospital in Fort Collins. Two years later, she was tapped to lead the design, construction and development of Greeley Hospital and its adjoining medical center.
“I often say that Northern Colorado has some of the best health care in the country, and it has been an honor to be part of it for all these years,” Schock said in a prepared statement. “While I will miss working with the phenomenal people at UCHealth and Greeley Hospital and their passion for improving lives, the time feels right to retire and begin discovering my next purpose.”
A native of Cody, Wyoming, Schock earned a bachelor’s degree in occupational therapy and a master’s degree in business administration with an emphasis on health-care strategy, both from Colorado State University.

Her career began as an occupational therapist at McKee Medical Center in Loveland in 1985. She was director of rehabilitation at the hospital from 1991 to 1999, then served in several leadership roles at Banner Health facilities leading up to her being named CEO at McKee in 2009. She held that position until being tapped by UCHealth five years later.
“Marilyn has built an incredible legacy in northern Colorado,” Kevin Unger, CEO of UCHealth’s Northern Colorado region, said in a news release. “Thanks to her leadership, more people in our region now have access to the high-quality care they need to live healthier lives. She also has fostered a strong, patient-centered culture that supports staff members, physicians and advanced practice providers alike.”
Since the Greeley hospital’s doors opened, its staff and providers on its campus cared for patients during almost 9,000 admissions and observation visits, 43,000 emergency room visits and almost 200,000 outpatient visits, according to the UCHealth news release. In fiscal year 2025 it has been the scene of 764 births.
Schock has overseen several projects at the hospital. According to the news release, “its inpatient bed capacity has grown by more than 70%, from 51 to 88 licensed beds. This includes the opening of a 12-bed progressive care unit, a 20-bed acute care unit, three intensive care unit beds, and two additional labor, recovery and postpartum beds in the birth center. Other projects added operating rooms and a second emergency trauma bay and expanded the hospital’s kitchen and cafeteria. The hospital also recently launched a construction project that will expand the emergency department by nine exam rooms and three intake rooms by summer 2026.”
Hospital officials said UCHealth soon will begin a search for the hospital’s next president.
