Meet our board of directors


Greg and jeanette Summerville

CEO & Board Member


Bob and Nancy Royster

President & Board Member

El Progreso, Jutiapa, Guatemala

Greg is a General Contractor and Jeanette is an RN. They have 8 children, all of whom they home-schooled, and 15 grandchildren. They founded the ministry in 2010 and incorporated in 2011 because they quickly realized that with a multitude of counselors there is safety (Proverbs 11:14).

God has used them throughout their 42 years of marriage to teach children the word of God. Jeanette uses her skills in art to illustrate Bible story booklets which help the Deaf learn the stories, since most cannot read. Greg loves to teach the boys carpentry and welding.


Their Sundays are busy with Jeanette teaching the children's Sunday School classes and Greg helping Jonathan with the preaching.
