Our Staff


Pastor Chris and Jeannette Willis
Lead Pastor and Discipleship Pastor

Pastors Chris & Jeannette Willis met while they were both attending Central Bible College in Missouri, and man, are we glad they did! Though they have served in Massachusetts and various other capacities in Connecticut, the Lord has blessed us greatly to have these 2 giants in the faith serving as our Lead Pastors at Cornerstone for over 10 years. They have 3 children: Shalyn, Ashlyn, & Russell. Shalyn is a graduate from Northpoint College, while Ashlyn is a senior at Oral Roberts University. Russell is in high school at Faith Prep and an active member of our FORGE student ministry. Jeannette favorite dish is chicken cutlets w/ roma tomatos, basil, & honey mustard. She enjoys walks on the beach with her "CUTE MAN," as well as walks with the fam pretty much anywhere. She enjoys basketball, volleyball and playing games, especially "Party Bowl"! She loves trucks, cool blinkers, and the ocean is her favorite place. PC loves to eat tacos, deviled eggs (despite their name), as well as dairy-free/gluten-free chocolate cream pie (yes, that does exist). He also loves cross country drives (like, LONG ones), family trips to the beach, and working on house projects. He enjoys listening to preaching podcasts, reading Christian fiction with Russ, as well as hanging out at the house with family, when there's nothing to do & nowhere to go, just company to enjoy. Lastly, he really enjoys the game Risk and wants you to know, "I'm pretty awesome at it". Haha

Pastor Russell and Ethel Grant
Associate Pastors, Prayer and Pastoral Care

Pastor Grant grew up in Minnesota before serving in the U.S. Navy. While in the Navy, he was saved and called to attend Northpoint Bible College (then Zion) to prepare for ministry. It was there that he met the lovely would-be Mrs. Ethel Grant, and they were married in 1964. They have been in ministry for over 50 years together (praise God). They've pastored 4 churches together, have led multiple ministries together, and have 4 daughters and 12 grandchildren. When asked their favorite meals, Pastor Grant went with pork tenderloin, mashed potatoes w/ mushroom gravy, and veggies, whereas Mrs. Grant would take a turkey dinner with all the trimmings. Pastor Grant enjoys Hallmark movies, outside games, and would spend his ideal Saturday driving down to the ocean. Mrs. Grant's favorite movie is the Sound of Music, and also enjoys watching Wheel of Fortune, but she, too, enjoys the beach, as well as playing games, walking, and spending time with friends & family. The Grants bring such invaluable experience, wisdom, knowledge of the Word of God, and sensitivity to the Holy Spirit to our team, and we are forever grateful for their presence and impact on this church and their hearts for the lost.


Pastors AJ & Heather Johnson
Youth Pastors


AJ & Heather Johnson have been members of the Cornerstone staff since January 2021, and currently serve as Youth Pastors for our Forge Student Ministries, as well as provide pastoral oversight for our Next Gen Ministries and Fuse College/Career Ministries. They previously served as Youth, Young Adult & Life Group Pastors outside of Charlotte, NC. Heather is a graduate of Liberty University with a Bachelor’s in Youth Ministry and a minor in Women’s Ministry. AJ is a graduate of the University of North Texas with Bachelors degrees in both Spanish & Communication Studies. They met while working in camp ministry at Clayton King Ministries, and have been married for 7 years. Heather & AJ have massive hearts for the next generation, and care deeply & specifically for the teenagers in our Forge Student Ministry. Their ministry model is life-on-life discipleship that focuses on meeting students where they are, teaching them about deep truths of Scripture, developing deep community, and giving students a firm foundation of faith to stand on as they venture into adulthood. Feel free to email AJ ( ) or Heather ( ) with any questions you might have for them. Their ideal Saturday would be spent by the water: beach or lake!

Jaclyn Mattison
Children's Pastor

Jaclyn was born and raised in Connecticut. She currently resides in Sherman with her husband, Shawn and 7 children ranging from 20 years old to a newborn. She is new to the Cornerstone team and will be overseeing children’s ministry. She has many years experience in education and ministry and is excited to have the privilege of pouring into our youngest generation and partnering with parents to traverse the complexities of childrearing in this unprecedented time. Jaclyn is very active and loves spinning and running as well as keeping up with all of her kids sports and dance activities. Her ideal Saturday would be a day spent with her family followed by an ocean view date, complete with lobster, with Shawn.

Jonah DeJarnette
Technical & Creative Director

Jonah DeJarnette takes care of all things tech for Cornerstone. He recently graduated from the University of Bridgeport, with a Computer Engineering Technology degree. He has a passion for serving in production and tech ministries, and enjoys being around for events of all kinds. He's also a graduate of our own Forge Student Ministry, where he now serves as a youth leader. Jonah feels called to vocational ministry, and is passionate about allowing others to see Christ through the world of Technology and Creativity. Outside of church, Jonah loves to play golf, dabbles in casual photography, and hangs out with close friends whenever he gets the chance. His ideal Saturday would be 18 holes in the morning, followed by hanging out with close friends for dinner that evening.

Susan Nute
Office Administrator, Women's Ministry Leader

Sue has served as our Office Admin for the past 7 years, and man, are we blessed to have her. If you’ve called the church at any time during those years, she’s probably been the first voice you’ve heard. She takes care of all of our office's administrative needs, and also is the leader of our Anchored Women's Ministry. She’s lively, fun, energetic, and loves to connect with, empower, and build up women through building relationships & studying God’s Word. Sue is married to her husband, Bob. They have two children and 4 grandchildren. She & Bob “love love love” to travel and have a dream to drive across the U.S. at some point. They also have a lofty goal to one day climb Mount Washington. She’s pretty much down for all impromptu travel, especially if it’s to New Hampshire to visit Rob & Heidi (their son & daughter-in-law). They’ve recently discovered a new love for paddle-boarding! She enjoys home-reno shows and funniest home videos, but would rather play a game. She likes online trivia and is always up for a board game, especially Scrabble. Her favorite foods are ham & scalloped potatoes, as well as Hungarian food, Hibachi, and chocolate covered gummy bears! Her ideal Saturday would be spent with her grandsons: Bentley, Logan, Grayson, and Elijah sleeping over, making them their fav: Nutella pancakes & bacon, then going for a hike or any other fun activity we can come up with!

Carlene Kopchak
Bookkeeper, Jubilee Ministry Leader, LAND Ministry Leader

Carlene Kopchak serves as the Bookkeeper at Cornerstone, making sure Cornerstone is a faithful steward of the resources with which God has entrusted us. Carlene was only “supposed” to be on our team for a short period of time, but God had other plans, showing her that she was called to this position, and God has given her the talents & abilities she has for this specific purpose. Carlene is also over our Jubilee Ministry, with which she seeks to engage & serve the 50-and-up crowd of our congregation, as well as our LAND ministry, which is an outreach ministry specifically desiring to reach our local community. Her and her husband, Andy, have been married for 47 years, and have a son, daughter, and 4 grandchildren. Andy also serves as a member of our board & takes care of many of our building's maintenance needs. Carlene enjoys watching Star Wars & Les Miserables, loves a good pizza, chicken francese, and anything chocolate. Her ideal Saturday would be spent taking a walk or sitting on a quiet beach.


Ashlyn Willis
Social Media Coordinator

Ashlyn is no stranger to Cornerstone Church. She's blessed us all throughout the years with her willingness to serve and her heart for the Lord,  and we are so blessed to have her on our team! Currently, she's a senior at Oral Roberts University, and takes care of all of Cornerstone's social media presence. Ashlyn is pursuing a degree in Business, and her current post-college plans include getting her real estate license. In her off time, she loves to work with and ride horses whenever she can, and loves to use her passion for healthy habits to encourage and inspire others to do the same. Lastly, Ashlyn loves Jesus with all her heart & loves serving this church through social media.

Dee DiVincenzo
Cleanliness Coordinator, Coffee Ministry Leader, Wedding Liaison

As you can see above, Dee wears multiple hats for our church. She keeps the church clean on a regular basis. She also heads up our coffee ministry, which we can't engage in during this time, but she misses it dearly! Her desire is to cultivate fellowship for our church as well as an opportunity to meet new people who begin attending our church. She has an amazing coffee crew of volunteers who help out weekly when that ministry's up & running. As an aside to that ministry, alongside her team of volunteers, Dee often takes care of food catering needs for church social functions, as well as any "in-house" wedding coordination that takes place at or with Cornerstone. Dee also enjoys being a part of the Anchored Women's Ministry. Her daughter, Allie, was formerly a Kidz volunteer, and we're sure you've met her husband, "Big Joe," who heads up our ushers & security teams. Dee enjoys cooking meals (which Big Joe will tell you are hard to beat!), and LOVES to entertain guests in her home. One of her favorite scriptures that she tries to embody in her role at the church & her daily life is Colossians 3:23, which says: "Whatever you do, work heartily, as for the Lord and not for men, knowing that from the Lord you will receive the inheritance as your reward. You are serving the Lord Christ."
