Board Member

Dr. John G Demakis

In 1998, Dr. John G. Demakis, a long-standing member of Chicago's Greek Orthodox Community, moved to Washington DC to accept the position of National Director of Health Services Research and Development Service for the Veterans Health Administration. He was previously the Director of the VA's Midwest Center for Health Services, and Policy Research based in Chicago for 15 years.

While in Chicago, Dr. Demakis also led the study that developed the National Surgical Quality Improvement Program that successfully decreased mortality and complication rates in surgery performed in the VA. One of Dr. Demakis' major new initiatives in Washington was to initiate the VA's Quality Enhancement Research Initiative.

Dr. Demakis has been very active in the Greek Orthodox Community in Chicago. From 1976-1980 he served as president of the St. Demetrios Community of Elmhurst, Il. In 1961, he was sent to New Delhi, India by Ecumenical Patriarch Athenagoras of Constantinople to represent the youth of the Greek Orthodox Church at the World Council of Churches International Meeting. Dr. Demakis was a founding member of the Orthodox Christian Association of Medicine, Psychology and Religion (OCAMPR) and served as the president of the local chapter. He was also as member of an IOCC team that went to Moscow, Russia in 1992 to do a needs assessment for the Russian Orthodox Church as they prepared to expand into medical care. He has also served as the Chairman of the Scholarship Committee for the Hellenic Medical Society of Chicago for eight years.

Dr. Demakis, and his wife Katherine, now live in northern Virginia and attend St. Katherine's Greek Orthodox Church in Falls Church, Virginia. Dr. Demakis teaches The Journey to Orthodoxy, a class for those who want to learn more about our Church or who are planning to become converts. Katherine sings in the church choir.

Prayer for Missions

God of truth and love: Father, Son, and Holy Spirit, Hear our prayer for those who do not know You. That they may come to a saving knowledge of the truth, and that Your Name may be praised among all peoples of the world. Sustain, inspire, and enlighten Your servants who bring them the Gospel. Bring fresh vigor to wavering faith; sustain our faith when it is still fragile. Continually renew missionary zeal in ourselves and in the Church, and raise up new missionaries who will follow You to the ends of the world. Make us witnesses to Your goodness full of love, full of strength, and full of faith for Your glory and the salvation of the entire world. Through the prayers of all the missionary saints, Have mercy on us and save us. Amen.
