Jack has been going to Cornerstone since 1987 and helped with repairs around the church before being asked to join full time. Now we are blessed with his ability and talents of building management and maintenance of facilities. The hard work that he does around the building such as all the cleaning, yard work, snow plowing, building repair, etc is what keeps Cornerstone going. He does full-time work in both the building and parsonage. Jack became a Christian at the age of nine in Vacation Bible School at Winnetka Bible Church which he attended until He was about 25 or so. When Jack is not working you can find him playing ice hockey once in a while or visiting with his six children and his two grandkids. 


Our Elders

The Elders of Cornerstone Church shepherd the flock by guarding, feeding, and overseeing those who have been entrusted to them. We praise God for these godly men called by God and approved by our congregation.

 Our Deacons

The Deacons of Cornerstone serve our congregation by caring for the many physical needs of our buildings and grounds. We are grateful for these qualified men of character and dedication to our people.

Our Deaconesses

"I commend to you our sister Phoebe, a servant of the church at Cenchreae, that you may welcome her in the Lord in a way worthy of the saints, and help her in whatever she may need from you, for she has been a patron of many and of myself as well." - Romans 16:1-2

The deaconesses of Cornerstone serve the body in a variety of ways from planning wedding and baby showers to assisting with funeral needs for grieving families. They also keep areas of our church clean and tidy, prepare the elements for the Lord's Supper and provide meals for families in need.
