Rosa, a Lieutenant Colonel in the U.S. Army, will focus on the new administration’s efforts to streamline county government, according to the press release issued Monday.
Rosa has been a top adviser to U.S. diplomats and military leaders, and has held key roles with the U.S. missions to Iraq and Bosnia-Herzegovina. He also developed U.S. responses to humanitarian crises in Haiti, Libya and Syria.
“Guillermo has the world class experience I need on my team as we take on the daunting task of righting Rockland’s ship,” Day said. “He has worked under the most difficult circumstances imaginable to bring peace and order to parts of the world that have known nothing but pain and suffering for generations.”
Rosa has announced his retirement from the Army to take his new role on Jan. 1, 2014 in the Day administration, in which he will also serve as Deputy County Executive.
“I feel honored to be Ed Day’s chief of staff and for the opportunity to serve the people of Rockland,” said Rosa, a Rockland resident. “I look forward to implementing a bold new effort to put Rockland County on a sound fiscal footing and create a business-friendly environment that encourages job creation.”
Day said Rosa would use his extensive management experience to do more for the county with fewer resources, including a County Executive’s office that will be less costly than the previous administration. Day will take a 10 percent pay cut as county executive.
Although assigned to the Pentagon, Rosa currently works at the U.S. Mission to the United Nations, traveling extensively since 2009. From 2006 to 2008, Rosa served in Iraq. In 2003, he represented the U.S. Department of Defense in sensitive interactions with the new Bosnian military and civilian leadership.
When not on Active Duty, Rosa also served as assistant director of developmental disabilities for St. Dominic’s in Blauvelt, where he had administrative responsibilities and operational oversight of multiple work sites with a budget of more than $19 million.
Rosa has received numerous awards, including the Bronze Star, the Iraq Campaign Medal, the National Defense Service Medal, Army Commendation Medals, Army Achievement Medals, NATO Medal, Expeditionary Medals, Armed Forces Service Medals, and the Army Service and Overseas Service Ribbon.
Rosa studied social and political science at the University of Puerto Rico and has a master’s degree in public administration from Marist College in Poughkeepsie. He took part in a wide variety of military advancement programs, ranging from the U.S. Army Command and General Staff College to courses on disaster management and crisis response, as well as cyber security and counter-terrorism awareness.
Rosa lives in Garnerville with his wife and has a son in college. He is active in the American Legion and has served on the board of the Rockland County Youth Bureau.
Day takes office as Rockland’s third county executive on Jan. 1, 2014, when he will be sworn in at 11 a.m. at the Rockland County Fire Training Center on Firemen’s Memorial Drive in Pomona.
The ceremony is open to the public.
