Corrie Johnson

B.A. Christian Education, Wheaton College, 1996
M.A. International Education, SIT Graduate Institute, 2017

Assistant Director of Summer Programs

Corrie’s life trajectory can be attributed in large measure to the
experiences and learning gained through
time spent in various cross-cultural settings while a student at Wheaton through involvement in the OCO and as a HNGR intern. Because of this, she is passionate about opportunities that enable her to support others, specifically college students, to pursue similar paths in this crucial life-shaping period of their lives. As Assistant Director of Summer Programs, Corrie seeks to nurture leadership development and provide
supervision of students involved in Youth Hostel Ministry, Student Ministry Partners and Global Urban Perspectives. All three of these ministries offer service-learning opportunities for students to engage in,
both domestically and internationally, and grow in their capacities as competent global citizens and bridge
builders through partnership with others involved in God’s Kingdom work around the world.


Jared Falkanger

B.A. International Relations, Wheaton College 2013

Assistant Director of School Year Programs

Jared came to Wheaton as undergraduate from the great state of Minnesota and has spent the last 10 years in, and around the greater Chicago Area. His Minnesotan identity and accent especially comes out when he engages in conversation about his favorite baseball and football team. Jared loves his work with students as Assistant Director of School Year Programs, as he works to support, train and develop student leaders involved in Christian Service Council, Breakaway Ministry, and Zoe's Feet. He especially enjoys the way that service draws out and forms identity in the image of Christ. Jared also spends time investing in community partners all over the Chicagoland area. He has a passion to empower the next generation of leaders to use their gifts and talents for the Kingdom.



Tuesday Whittington

B.A. Science, Wheaton College 2017

Office Coordinator

Tuesday is the Office Coordinator for the Office of Christian Outreach. She was raised in the Chicagoland area with her six siblings. She has a passion for women's rights and is a first-generation college -graduate class of 2017 Wheaton College alumna. Tuesday spends her workday supporting students and staff with her skills in multi-tasking, organization and administrative guidance. She can often be heard singing while deeply focused on a task, eating chocolate, or excitedly sharing about her most recent read. She also wonders if anyone really believes this whole third-person thing, or if everyone knows she wrote this herself.


Esther Tschappler

Graduate Assistant

B.A. Biblical Studies with Education, African Bible University 2017

Esther is the third of six children, and was raised in a small town in the beautiful state of Colorado. She was happily settled in the shadow of Pikes Peak until God gave her the opportunity to go to Uganda, first as a homeschool teacher for a missionary family and then as a college student. Her experiences in East Africa gave her a greater appreciation for the unity of the Body of Christ, the splendid array of differences between peoples and cultures, and some of the challenges and joys of living and ministering across cultures.

Esther is passionate about caring for “the least of these,” particularly vulnerable women and girls. In her natural habitat, she can often be sighted reading, biking with her younger brother, spending time with friends, attempting to learn another language, or cooking “odd but good” foods.



Kassie Walters

B.A. Psychology,  Valparaiso University 2017

Graduate Assistant

Kassie was raised in a 'bring your tractor to school day' type of town in Wisconsin and recently moved to Wheaton from outside of Minneapolis where she enjoyed biking to work, going to theatre performances, exploring the Arboretum, and spending time with her nieces and nephews. Kassie graduated from Valparaiso University in 2017. Some notable memories include repelling down a fire tower, being a RA, 'super-manning' down the longest zip-line in Latin America, presenting at MPA, and polkaing. After graduating, she did a year of ministry at HoneyRock where she witnessed and experienced God's love and faithfulness. Kassie is an aspiring career counselor in higher education who is excited about helping people find where their passions, skills, and values intersect to meet the needs of others. In her free time, you can find her playing basketball, drinking coffee, nestled up reading a good book, or laughing (probably at her own jokes).
