Douglas VanHouten

Douglas is Grace's administrator.  He is responsible for communications (including our website and Facebook page), finance, facilities rental, scheduling, and along with the rest of the staff consults around visioning and programming at Grace.  If you have a question about your pledge balance, a reimbursement check, scheduling an event, Grace's website, a building issue, holding a concert or program at Grace, submitting an online registration form for formation programs, donating securely online, Douglas is your go-to person. 

Douglas served on the Commission on Ministry in the Episcopal Diocese of Chicago for a six-year term and was the first layperson ever appointed by the bishop as its vice-chair.  He has a deep passion for discernment of gifts and ministries.  He is a firm believer that all baptized persons are ministers and therefore takes great delight in watching and helping others find ways they might best offer their gifts and talents toward the building of community.

A Colorado native, Douglas—an avid skier, hiker and biker—is still looking for the mountains in Illinois when he's not busy gushing about his two nieces or puttering about his garden and pond.  Douglas is married to an Episcopal priest.

The Vestry is the body within a congregation that, with the clergy, leads the parish. Grace’s Vestry meets monthly, on the fourth Tuesday at 7:00 pm, usually in the St. Hilda Room (2nd floor of the Parish House). In addition the Vestry periodically schedules additional and/or special meetings as needed. ALL Vestry meetings are open to members of the Congregation.  The schedule for Vestry meetings is at this link.


Deborah Maue is a life-long amateur singer and pianist. She has been a member of church choirs since the age of six, and currently sings soprano in the Liturgical Choir of St. Christopher’s Episcopal Church, where she also serves on the vestry. Deb and her husband, Terry, live in Oak Park with kids: Emma (a future law school student), David (a freshman at OPRF and a member of the Madrigal Choir), and Margaret (a 7th grader at Julian Middle School and a member of the Schola Choir). She has a B.S. in Marketing from Juniata College in Huntingdon, PA and an MBA from the Kellogg School of Northwestern University. For the last 12 years, Deb has served in senior marketing positions in higher education and is currently the VP for Marketing and Communications at Aurora University in Aurora, IL. She is very excited to be assisting with the youth choirs of Grace Church, because (among other reasons) it will force her teenage children to interact with her.

Vestry & Officers

Andrea Bartolomeo is an educator, organist, pianist, and pastoral musician. She has been
accompanying choirs and instrumentalists since the age of 14 and is known for her sensitivity as
a collaborative musician. She is on the piano faculty at Sherwood Community Music School at
Columbia College and serves as Associate Director of Music/Organist at St. Paul of the Cross

Ms. Bartolomeo has over 25 years of teaching experience in the private and small group setting.
After operating a successful home studio of over 100 students, she and her husband, Luke
founded and directed the Music Schools of Northwest Ohio (Perrysburg, Sylvania, and
Findlay). In her role as artistic director, Andrea planned educational programs (recitals,
masterclasses, and outreach programs) to provide valuable performance and service
opportunities for their students in local nursing homes, senior centers, and libraries. As a piano
duettist, Andrea performed with her husband, Luke, in Ohio, Michigan, Texas, and Illinois.

For the past several years, she has delighted in attending rehearsals, Cleveland tour, and other
events of the Schola choir with her 4th-grader, Gigi. There is nothing greater than being in the
presence of dynamic, friendly kids, who love to sing together!

Thank you, Rev. Mary, Dennis, and Grace Episcopal Church, for this wonderful opportunity to
assist the youth of our community!

Jon has been a member of Grace since 1982, and has served as a deacon at Grace since 2004.  His main work at Grace is to encourage and enable the people of Grace to help the needy, whether inside the parish, or in our neighborhoods, our region, our nation, or the world.

Jon serves as a volunteer in the church.  Outside the church, he is a Senior Software Developer at the Railroad Retirement Board in Chicago.  (If you're having trouble falling asleep, ask him to explain the intricacies of unemployment benefits for railroad workers.)  He has worked there for over 30 years, and has occupied cubicles within a 50 foot radius on the same floor since 1988.

Jon is married to Marion.  They have two adult children, Martha and Peter, who both live in Chicago.

Mary Slenski
Interim Rector

The Rev. Mary Slenski comes to Grace Church from the Diocese of Indianapolis.  She finds joy in working with congregations in transition as they claim the blessings and embrace the future God most desires for them.  Grace Church is her fourth appointment as an Interim Rector. 

 Ordained in 2008, Mary holds a Master’s of Divinity from the Episcopal Divinity School, an MBA in Finance from Wright State University, and a Bachelor of Science in Engineering from the University of Florida.  (Go Gators!)  During a sabbatical in 2016, she completed additional graduate coursework in Philanthropic Studies from the Indiana University Lilly Family School of Philanthropy.  

 In Mary’s own words: “The most important things about me are not how I came to occupy the rector’s office at Grace Church, where I grew up or went to school.  The most important words I can use to describe myself are simply these: beloved of God, follower of Jesus of Nazareth, priest; and then, wife, mother, godmother, sister, daughter, neighbor and friend.  I love being near large bodies of water, mountains, and the giant Redwood trees.  I’ve had a needle in my hand since before I could read and enjoy quilting and ethnic textiles.   And, congregations undergoing transition are special to me.”

Mary has been married to George since 1980.  They enjoy travel, theater, and especially, their two adult daughters, Denise and Abigail.
