IACH Welcomes CSM Hadley to Big Red One Community
Command Sergeant Major Masasinge B. Hadley assumed responsibility as the senior enlisted advisor of Irwin Army Community Hospital during a ceremony Sept. 22, 2026, succeeding CSM Meredith R. Greene, who is retiring from the U.S. Army.
COL Jason K. Marquart, the IACH Commander, presided over the event, which was attended by regional civic leaders, senior Fort Riley leaders, local healthcare partners, and the Soldiers and civilian staff of the hospital. The ceremony celebrated CSM Greene’s 24 months of leadership at Fort Riley and formally charged CSM Hadley with his new role as the hospital’s senior enlisted leader.
In his address, COL Marquart thanked CSM Greene for her leadership and daily mentorship over the last two years, noting her work to align hospital operations with Army Medicine’s strategic priorities.
During her 24-month tenure, CSM Greene managed several key initiatives that directly impacted both patient care and hospital personnel. She successfully advocated at higher headquarters to prevent service reductions at IACH, preserving the hospital’s inpatient capabilities. Under her leadership, the hospital also executed Operation Victory Realignment, which relocated the Soldier Readiness Processing site and the Armed Forces Wellness Center, integrated mental health services into the Farrelly Health Clinic, and reopened the Custer Hill Dental Clinic. Additionally, CSM Greene established a structured development program for junior leaders, served on the hospital’s People First Council to address staff concerns, and personally volunteered nearly 350 hours with local community organizations.
COL Marquart also read a message from the former IACH Commander, COL Laudino Castillo Rojas, who recalled working with CSM Greene during a 43-day government shutdown. COL Castillo noted that CSM Greene organized food pantries and identified local resources to support affected hospital staff while keeping daily healthcare operations running.
“Thank you for helping me be an effective leader by having hard conversations late at night, making sure that I was at the right place and time, and for checking on my welfare as a person,” stated COL Castillo’s message.
CSM Greene used her final address to thank the hospital staff, the 1st Infantry Division, and regional healthcare partners for their collaboration. She emphasized that healthcare quality ultimately relies on the daily competence and commitment of individual staff members rather than the physical facility itself.
“The position gives you responsibility, but the people give you the meaning,” CSM Greene said. “Every day, I watched this team care for others, often quietly, often without recognition, and frequently while carrying burdens of your own.”
She closed with a direct charge to the leaders and Soldiers in the formation:
“Lead from where you are. Be present, listen, tell the truth, and develop people for responsibilities beyond their current role. Protect standards without losing compassion. And when the mission becomes difficult, resist the hesitation to retreat into individual lanes. Move toward one another and solve problems as a team.
CSM Hadley took the podium to address his new team, thanking his family and his predecessor for setting a high standard of leadership.
“CSM Greene, thank you for your exceptional leadership,” CSM Hadley said. “You are truly a difficult act to follow. I will try to sustain what you have built and see where we can go together.”
Addressing the hospital’s leaders, Soldiers, and civilian staff, CSM Hadley outlined a set of leadership expectations and priorities. He emphasized that effective leadership is defined by daily presence and actions rather than position or tenure, urging leaders to remain visible and engaged with their teams. He said that his primary focus will be the safety, welfare, and operational readiness of the hospital’s Soldiers. Finally, he committed to maintaining and strengthening IACH’s collaborative relationships with the 1st Infantry Division, Fort Riley tenant units, and the surrounding community partners.
