Leadership changes at U.S. Army Public Health Command
May 23, 2013
Maj. Gen. Dean G. Sienko assumed command of the U.S. Army Public Health Command in a May 23 ceremony at the Top of the Bay on Aberdeen Proving Ground, Md.
Sienko replaces Maj. Gen. Jimmie O. Keenan, who will become commander of Southern Region Medical Command, Joint Base San Antonio, Texas.
Reviewing official Maj. Gen. Richard A. Stone, deputy Army surgeon general, congratulated Sienko and called the USAPHC "a jewel in Army Medicine."
Keenan expressed gratitude for the opportunity to serve as the commander of the USAPHC and pride in the public health experts she led.
"Every day, you promote the health, wellness and resiliency not only of Soldiers, but also of the military families that support them. By enabling readiness, you serve as a force multiplier," she said.
Sienko said he is looking forward to working with the members of the U.S. Army Public Health Command's team as the organization maintains a legacy of outstanding service to Soldiers and retirees, their families and Army civilians.
"It gives me great honor to receive the colors of Army Public Health Command," he said. "What a tremendous gift it is for me to assume the command of an organization that has an outstanding reputation and does such good for our Army family. Public health is my passion. I look forward to working with all of you and learning from you."
Sienko is the 4th commander to lead the U.S. Army Public Health Command. He heads a worldwide organization with approximately 3,500 Soldiers and civilians stationed in more than 100 countries. The USAPHC promotes health and prevents disease, injury and disability in Soldiers and military retirees, their family members, and Army civilians, and assures effective execution of full-spectrum veterinary services for the Army and Department of Defense.
Prior to accepting his new position, Sienko served as the associate dean for prevention and public health in the Michigan State University's College of Human Medicine. He is a physician board-certified in general preventive medicine and public health.
