Mr. Vagelos, a member of Leadership 100, is a telecommunications industry executive, who also unselfishly offers his time and talent to serving the ministries of the church. He has assisted the Archdiocese staff in putting in place many valuable internet projects, such as Light a Candle, Say a Prayer, and Make a Donation. In addition to other duties, Mr. Vagelos ably directs live streaming services from St. Mark and has instructed many parishes, especially during the Covid-19 quarantine, how to place live streaming in place from their houses of worship.
