  • Peter Hawkinson

    Senior Pastor

    Peter is a lifelong Covenant member with a passion for helping people of all faith backgrounds and walks of life forge a closer relationship with God. He grew up on Chicago’s North Side, attending North Park Covenant church. His dad was a pastor and editor of The Covenant Companion. After earning degrees from Covenant Bible College, the University of North Dakota and North Park Theological Seminary, Peter joined Winnetka Covenant in 1989 as youth pastor, and went on to pastor Covenant churches in Seattle and Minneapolis. Peter rejoined Winnetka Covenant as associate pastor in 2001, and has served as lead pastor since 2005. An avid reader (especially historical fiction), Peter likes music, sports and coffee. He and his wife Bonnie—new empty-nesters—have three daughters who, he says, “fill our lives with laughter.”

    What you wish people driving or biking by our church—who don’t worship anywhere—knew.

    "That, despite what the church has often witnessed to, God is profoundly FOR you, full of love. That God’s people deeply care and want to support and share your journey. And that our Wednesday night dinners are the best deal on the North Shore!"

  • Jen Christianson

    Associate Pastor

    Jen loves to connect with and nurture people in their walk with God, bringing her vibrant faith and intellectual curiosity to each encounter. She grew up in Attleboro, Mass., attending the local Covenant church. She earned her B.A. degree in history from Gordon College in Wenham, Mass., and her Master of Divinity degree from Princeton Theological Seminary. Prior to coming to Winnetka Covenant in 2018, Jen was a three-year Pastoral Resident at Covenant Presbyterian Church In Charlotte, North Carolina. In her new post, she is focusing on pastoral care, adult Sunday school, Wednesday night group discussions and older adults at Covenant Village. “I fell in love with Winnetka Covenant,” Jen says. “You have a deep heart for the gospel, and a deep love for each other.”

    You just joined us at Winnetka Covenant. Why our church?

    "I get to do all the things here that I love! I’m passionate about education and bringing people together to explore and learn. I also have this heart for pastoral care and our senior members. And I get to preach. It felt like a gift from God to have a call that offered all these things. I’m also impressed with Winnetka Covenant’s heart. You don’t shy away from tough conversations—but I see such grace and compassion framing the way you speak to each other. That’s something I want to be part of."

    You’ve helped lead our church for more than 50 years. A highlight memory?

    "It was Mother’s Day, 1973—the first time our members gathered to worship in our current sanctuary. After years of prayerful, spirit-charged anticipation, I can remember kneeling on the steps below the communion table and cross, tears in my eyes. I was so filled with amazement and gratitude to God. We were transforming our place of witness in the community. That moment was—and remains today—a holy time in my life, matched rarely before or since as pastor."

  • Judi Geake

    Spiritual Direction and Small Group Ministries

    Judi is well-known for her success planning programs that address the special needs of women. She spent 20 years as executive director of the Women’s Exchange, a Winnetka nonprofit organization serving women across the North Shore, retiring in 2011. Judi was born in Canada and grew up Lutheran. Her family moved to Chicago in 1962. She married Howard in 1968, and they have three sons and eight grandchildren. Her family joined Winnetka Covenant in 1983. Judi earned a bachelor’s degree in marketing from Valparaiso University; got her master’s in counseling from National Louis University; and in 2014, received her Certificate in Spiritual Direction from North Park University. “Maintaining and deepening our relationship with God can be daunting during the best of times,” Judi says. “But making God a priority in our stress-ridden, time-challenged world can sometimes feel impossible. I want to create opportunities for people to deepen their spiritual growth through small groups and discussion. Spirit-filled people can’t help but spill out that fullness to their families, their work places, their communities and, most important, their church.”

    Any new ministries you’re thinking about where you see a real area of need?

    "I’ve been asked to launch a group for women who are living as singles for the first time. I’m also starting a group called 'Come Play With Me,' for women who just want to have fun in the company of other women. I also want to launch a monthly discussion group that delves into short articles or book chapters by people of faith who inspire us to ask questions and explore. I’m busy growing these ideas!"

  • Melissa Nelson

    Children's Ministry Associate

    Melissa has devoted her life to teaching kids, serving for 30 years with the Wilmette school district, where she primarily taught kindergarten. She grew up in Northern Colorado, attending a Presbyterian Church, and came to Chicago to study at North Park University, majoring in education. She married Pete Nelson in 1984, and they have three kids. Her family joined Winnetka Covenant in 1999 because of its wide-ranging offerings for children. In 2016, after retiring, Melissa was named WCC’s children’s ministry associate. In addition to planning Wednesday night kid’s activities, along with intergenerational programs, she plans Sunday morning worship programs for kids who take part in the first half of worship, then leave before the sermon. “On Wednesday nights, I want people from different generations to truly get to know each other,” she said. “On Sundays, I want our kids to feel loved and safe and nurtured, learning how God can truly be a part of their lives.”

    Your best moment on Sunday mornings with the kids?

    "Listening to them pray. I have this “prayer pail,” and kids can pull out topics to help them get started. Getting to hear them pray is the high point of my day."

In addition to directing our choir, he leads a Wednesday night praise band, and has launched a new children’s choir. “I want our music to enhance the solid theology we hear from the pulpit,” Dimitri says. “We also have such a diversity of musical tastes in our church--I want to explore both traditional and modern songs. And I encourage people to share their musical talent. It’s fun to showcase what people can do!”

    Your favorite hymn?

    "It’s “Evantide,” a well-known British hymn from the 1800’s. You’ll find it in our Covenant hymnal (#757) under the title “Abide With Me.” It’s based on Luke 24:29. My top pick."

  • Joshua Smith


    Joshua is an accomplished organist who has served our congregation for more than 15 years. He grew up in a musical family and began studying piano at age five. Joshua discovered the organ after visiting a friend who plays professionally in the Washington D.C. area. He quickly launched a search to find a competent instructor, and found Devon Hollingsworth, a world-class organist with Christ Church of Oakbrook. Joshua studied with him for two years, and then played professionally for several churches before coming to Winnetka Covenant in 2003 as a substitute organist. That same year, Joshua stepped into his fulltime role, helping lead our congregation in worship from the organ bench.

    How many songs or hymns do you play in an average service?

    "Anywhere from 9 to 15. That always surprises people!"

She spent 17 years working for the Covenant church’s denominational offices, and joined our church office staff in 1999. Judy has two grown daughters. In her spare time, she likes to garden. “This church attracts such a mix of people from all backgrounds and walks of life,” Judy says. “That’s why I love it here—I love the people.”

    You perform hundreds of different tasks to keep our church running smoothly. Your favorite?

    "Each year right before Easter I get to drive our church van to the florist to pick up the flowers for our big service. Oh, the colors and smells of those hydrangeas, begonias and lilies! We’ve just made it through winter, and I’m a gardener. It’s always a highlight."

  • Joan Wallgren

    Office Secretary

    Joan is a lifelong member of the Covenant church who brings her expertise and background to the church office. She grew up in Rockford, Ill., a fourth-generation Covenanter. She met her husband, John, also a fourth-generation Covenanter, at North Park University. They joined WCC in 1979, and have been singing together in the choir ever since. Joan joined WCC’s office staff in 2000. The mother of four grown children, and grandmother of seven girls and two boys, she also likes needlework and gardening. “Back in the 1880’s, my husband’s great-grandfather gave the keynote address for the first organizational meeting of the Covenant,” Joan says. “For me, the history and legacy of our family’s involvement here means so much.”

    What’s it like having your eight grandkids grow up as sixth-generation Covenanters?

    "I’m so touched when we sing the old Swedish hymns. My grandkids are learning the same music sung in church by their great-great-great grandparents! There’s also this: our family members going back to the early days of the church worshipped and worked with the composers who wrote those hymns. They probably knew them quite well!"
