Fairfield-Based Small Business Owner Promoted to Major in Illinois Army National Guard

Springfield, Ill. -

Illinois Army National Guard Capt. Henry Simmers was promoted to major during a ceremony on Nov. 7 at the 183rd Wing Headquarters in Springfield, Ill., recognizing his military service, professional development and contributions to logistics and his service to the United States.
Simmers enlisted in the Illinois Army National Guard in 2011 as an 88M motor transport operator before commissioning as a logistics officer through the Eastern Illinois University Reserve Officer Training Corps in 2014. Throughout his career, he has served in several leadership and staff positions, including truck platoon leader, executive officer, company commander and Officer Candidate School tactical officer.
"It's a great honor to be promoted in this organization, but it couldn't have been done without a strong support system at home," said Simmers. "Thank you to my parents and my wife for their constant support throughout my career. Thank you to my mentors who have guided me throughout these 15 years. I would be remiss if I didn't thank my staff at CSI Insurance who have covered for me while I have been away and unavailable for training. I am excited for this next opportunity and challenge in my career."
Simmers serves as the brigade logistics officer (S4) with the Peoria 65th Troop Command Brigade, where he oversees all aspects of brigade's logistical readiness. The brigade headquarters was at the 183rd Wing for Joint Task Force training. The 65th and 183rd form a Joint Task Force headquarters in the event of a domestic emergency and National Guard call-up within Illinois.
Simmer's military career is supported by his civilian job in insurance. Simmers owns and operates CSI Insurance Brokers in his hometown of Fairfield, Illinois. Simmers earned a bachelor's degree in Sports Business from Eastern Illinois University in 2014.
Simmer's promotion marks another milestone in his 15-year military career, recognizing his years of service and experience in logistics. As a major, he will continue to apply his leadership and expertise in support of the Illinois Army National Guard's mission.
Simmers was joined by family members and fellow Soldiers for the ceremony, marking the occasion with those who have supported him throughout his military career.
As he assumes the responsibilities of his new rank, Simmers will continue to support the Army National Guard's mission through leadership, logistics operations and the development of Soldiers.
