Greg enlisted in the United States Air Force in December 1976 and went to Basic Training at Lackland AFB, TX the following July. After training at Lowry AFB, CO he was assigned to RAF Upper Heyford, England in August 1978. There he first met members of Christian Military Fellowship and Officers' Christian Fellowship and was very active in the base chapel, local Bible Study Groups, a Contemporary Worship Service and conferences with the British Officers Christian Union and the Association of Military Christian Fellowships. It was during this time Greg met the CMF Executive Director, Ernie Miller and felt God's call to military ministry.  At the end of his enlistment in 1981 he joined Ernie on a month long missionary journey all through Europe to meet and encourage CMF and OCF members and other military missionaries. This was his time "learn the ropes" of missions to the military.

Greg returned home to Colorado, enlisted in the Colorado Air National Guard and began attending Rockmont College. Also, Ernie Miller invited Greg to join the Office Staff of CMF at the Headquarters in Englewood, CO.  After graduating in 1984 he moved to Aurora, CO to continue ministry at Lowry AFB and to be closer to Buckley ANG Base where he was assigned. In 1993 Greg had the opportunity to cross-train at Keesler AFB, MS. Shortly after that he met Diane Emerson, an Air Force nurse leaving Active Duty. They met through a mutual friend from the OCF Bible Study. It did not take for them to fall in love and were married in nearby Pensacola, FL where Diane lived. Greg joined her in Florida after completing his training and was allowed to remain in the COANG, serving with an ANG unit in MS and being deployed overseas with other units from all over the country. In Pensacola they participated in Bible Studies, attended worship at NTTC Corry Station and assisted with ministry at NAS Pensacola.

Greg and Diane moved back to Colorado in 1996 to join a new Space Command Air Guard unit in Greeley and he began working full-time as a civil service ANG Technician. Diane continued working as a nurse. In 2008 Greg was medically disqualified from military service and he retired as a Master Sergeant after 31 years of service. In 2010 they moved to Maine to be close to Diane's parents. Greg continues his work with CMF by serving as the Directory of Field Ministry and compiling the monthly Prayer Letter, the "Battle Plan" and sending a daily email prayer reminder.  He is active with the Chapel ministry on Portsmouth Naval Shipyard, Kittery, ME and Pease ANG Base, Newberry, NH.

Since settling in November 1998 on the western shores of Puget Sound, God has opened many doors to impact lives with the Good News of Jesus Christ in fields that are ripe for harvest with far too few laborers. The Lord has given us favor with many of the military chaplains in the area, particularly with the Coast Guard and Navy, which are currently the focus of our ministry. Vic is involved weekly with Bible studies and prayer groups at the 13th Coast Guard District Office and the Support Command in Seattle, the Bangor Submarine Base Dining Facility and Brig, and at least monthly at Coast Guard Port Angeles commands through their weekly prayer breakfasts. Vic is also involved in one-on-one counseling, visits to cutters, trips to various commands around the Pacific Northwest and the entire West Coast, and leadership of our weekly home Bible study group. Cindy leads a military wives weekly Bible study, and we’re both involved with telephone, e-mail and snail-mail counseling and support.
