Though “called” to be a missionary doctor as a boy, Curtiss discovered later that science, which he loved, required math, which he detested! God continued however to provide assurance of His call for Curtiss to be a Salvation Army officer. In 1978, a year before officer training college, Curtiss was selected to be part of a Summer Mission Team to the Caribbean Territory, and spent nearly 8 weeks serving in towns and villages throughout Jamaica. It was the first of many short-term missionary trips over the years.
Sandy had no plans to be a Salvation Army officer, let alone a missionary! She wanted to be a nurse, or a flight attendant. During college, she discovered a love for numbers, and a keen affinity for organization and structure. And then God called her into ministry in The Salvation Army.
Together, with their two children, Justin and Megan, they served in corps appointments in the Midland Division, and in 2004 they were appointed to National Headquarters, where Curtiss served as Editor of YS magazine and Assistant Editor of The War Cry, and Sandy served as Finance Officer with responsibility for the accounting, property and IT departments. During that time, God led the Hartleys to make themselves available for an overseas appointment.
They came back to the CentralTerritory in 2008 and served for three years at the La Crosse corps, before being appointed to Divisional Headquarters in Detroit. Sandy was finance officer, and Curtiss was youth officer, before being appointed Divisional Youth and Candidates Secretary. During their year in Detroit, God opened a door for Sandy to go to Haiti to provide business and financial assistance setting up systems and organization.
In October 2011, God called Curtiss and Sandy to the other side of the world. Papua New Guinea (PNG) needed a Territorial Finance Secretary. In November 2012 the Hartleys moved to PNG where Sandy took on the role of Territorial Finance Secretary, and Curtiss became Director of Support Services and Projects Coordinator. Life for the Hartleys is much different in PNG, and they’re miles from family, including a brand new grandson. But God has called them and equipped them, and gives them daily assurance that He has a plan to use them in that distant land for His purposes.
