Our Leaders
SENIOR STAFF
Interim CEO - Mary Dean
Mary put her trust in Christ the summer before her senior year in college. Never in her wildest dreams would she have imagined ending up in full-time ministry. Yet, after receiving a master’s degree in biochemical genetics and wanting to follow Christ and say yes to opportunities the Lord provided, that’s where she found herself. Mary served as director of women’s ministry at two Dallas area churches, including 13 years with Stonebriar Community Church. She went on to get her Masters in Christian Education from Dallas Theological Seminary. She also served with ministries including Moms in Prayer, Thrive Ministry and the Association of Women in Ministry Professionals. Mary has been facilitating Entrust courses for over 12 years. She and her husband Glenn have been married since 1980 and have two sons and three grandchildren.
Executive Director, Equipping Women - Joycelyn Seybold
Although Joycelyn grew up in the church with loving Christian parents, she didn’t come to her own faith in Christ until the age of 30. She received a bachelor’s degree in linguistics at the State University of New York at Binghamton and a master’s in speech-language pathology at Teacher’s College-Columbia University in New York City which led to her working as a speech therapist for adults and children for many years. Joycelyn has served in children’s, women’s and cross-cultural ministries in local churches most of her adult life. When the Lord called her to full-time vocational ministry, she was equipped through a master’s in New Testament and Christian education at Dallas Theological Seminary and the Entrust Equipping Women's training. She lives in the Dallas-Fort Worth area of Texas.
