Mark Chagaris

Mark grew up in Massena, New York and attended the United States Air Force Academy.  There he met and married his wife Jennifer. They have been married over 20 years and have 3 wonderful children:  Lahna, Kylie, and Jay. After serving over 10 years in the active duty Air Force in Texas, Germany, South Carolina, and Oklahoma, they have called Dover home since 2006.  Mark still serves in the Air Force Reserve and he's also a commercial airline pilot. Outside of time with family, he enjoys golf, biking, swimming, and working around his yard.


Mark is humbled to serve in the church leadership and to be part of this ministry.  It has been simply amazing to witness what the Lord has done with this church and he is excited for what is to come in the exciting and challenging days ahead.  He stands on God’s command in the book of Jeremiah to “Call to me and I will answer you, and will tell you great and hidden things that you have not known” [33:3]. He is truly grateful for God’s abundance in grace and mercy.

Upon arrival in Delaware (1999), Johns family quickly joined Fenwick Island Baptist Church. Praise God for early salvation and baptism at age 13  while under the preached Word of God by Pastor Al Brininger and reinforced at home by both his parents Teressa and Richard McNeill. In 2012, John began attending Cornerstone church where he felt the call serve as a Bible Study teacher, Home School Teacher, Deacon and currently serves as an Elder with a focus on the Building and Grounds.  His passion is for the continued growth of those called by God; cultivating long term relationships, growing with one another, teaching and leading the body of Christ- as the Lord allows. 1 Peter 4:10 “As each one has received a special gift, employ it in serving one another as good stewards of the manifold grace of God.”

Carrie was saved 4 years ago through the preached Word of the Gospel at Cornerstone church and baptized immediately thereafter. She is now serving the household as a supportive wife, homemaker and homeschool mom. Proverbs 31: 25-29 “Strength and dignity are her clothing, and she laughs at the time to come. She opens her mouth with wisdom, and the teaching of kindness is on her tongue. She looks well to the ways of her household and does not eat the bread of idleness. Her children rise up and call her blessed; her husband also, and he praises her: “Many women have done excellently, but you surpass them all.””

The Clarks have been blessed with 5 beautiful girls; Alexis, Taylor, Natalie, Savannah and Moriah (passed before birth) and FINALLY have a boy, Matthias.  This family is truly blessed! Psalm 127: 3-5 “Behold, children are a heritage from the LORD, the fruit of the womb a reward. Like arrows in the hand of a warrior are the children of one’s youth. Blessed is the man who fills his quiver with them! He shall not be put to shame when he speaks with his enemies in the gate.”
