Meet Our Leadership Team

Jean and Gurry.jpg

Jean Chappel was very passionate about children. At the age of 14, she worked with children in Vacation Bible School to help children understand the Bible.  Throughout her life she worked with children in different states.  

Jean went to the University of North Carolina at Charlotte where she graduated with a degree in Biology with a minor in math and education.  She first worked as a researcher in the University of North Dakota and later had different jobs until she moved to St. Louis where she worked in the old Jewish Hospital and later joined the Washington University lab where she retired from in December 2014 after being diagnosed with stage 4 breast cancer.  

In Jean’s own words
“My passion it to teach little ones about Jesus.  The thought of a child starving makes me very upset.  After reading Samuel’s book about the plight of the Bambuti Pygmy peoples, I just had to get involved.  My bible study group took up the project of raising money to help with this cause.  The first thing, of course, that we did was to pray.  I believe God has blessed this effort beyond our wildest dreams.  All I can do is to praise God.”

Jean went to be with the Lord in 2017 and Gurry Chappel took over as

Chair of the board.
