OUR COUNCIL
-
randy steinheimer
president
My wife, Debbie, and I joined St. Mark’s in 1992, when our son Nathan was 5 years old.
Through the years Debbie and I served in the Education Ministry by teaching Sunday School,
serving on the Worship Team, and teaching Confirmation. At different times I served as the
Sunday School Superintendent, Co-President of the Child Development Center Board, and
the Church Council Secretary. After thirty-five years of teaching, Debbie and I retired from
West Aurora Schools in 2014, and continued to teach part time in the School of Education at
Aurora University until 2022. We are now grandparents and cherish our time with our two
grandchildren.
I have served as the President of the Church Council for the past four years and look forward
with great optimism to continue serving as your President. St. Mark’s has undergone a long
season of transition during my presidency, but during this past year, we truly saw the hand of
God at work. St. Mark’s was abundantly blessed with God’s love and strength in 2025—a truly
transformative year! I pray with you for His continued guidance and wisdom as we seek to
fulfill our mission of Sharing Christ’s Abundant Love in 2026. It is my humble honor to
continue to serve St. Mark’s.

JEANNE FLYNN
vice-PRESIDENT
My name is Jeanne Flynn, and I have been a member of St. Mark’s since 1993. I am married to
Michael, and we have one daughter, Rebecca (Becca) who is 29. We are all in the beginning stages
of planning Becca’s wedding, who became engaged on 12/6/25. I am currently teaching 8th grade
confirmation and am involved with the Children, Youth & Family Committee, McCleery School,
VBS, the Seeker’s women’s group and providing office coverage. Michael and I also support many
outreach programs and feel that this is one of the areas in which we are called to serve. Included
in this has been recent activity with social justice activity and protest over immigration issues.
As a tenured member of St. Mark’s and, with a social worker’s training and skill, I believe I
contribute to council through my gift of discernment and my ability to relationship build. I am
excited to see how and where St. Mark’s will continue to grow, and I want to be part of this
forward movement. With the addition of Pastor Krista and Deacon David, I have been involved
in a number of new and creative additions to worship and our children’s ministry and have found
them refreshing and renewing. St. Mark’s potential is yet to be realized, and I am invested in
continuing to be an active part in working towards it.

rob creaney
treasurer
My family has been attending St. Mark’s since 2015 and we became members in 2018. My
wife, Alisa, and I have four kids, three of which are now confirmed members, one is an active
member of the youth group and one is active in the confirmation process. 2026 will be my
fifth year as the Council treasurer, sixth year on council and will finish my third and final two year term. You can usually find me and my family supporting Saturday night worship. I’ve also
been helping on the Stewardship committee, the property team, the endowment committee
and I am currently one of three individuals who puts the building to sleep every night. What
we love about St Mark’s more than anything is the people and the sense of community.

JULIANA (jULIE) JOERGER
congregational secretary
I became a member of the Council in January 2025. Not only has 2025 flown, but we have had
a lot of new positive changes at St Mark’s. The new year started out with the goal of finding a
Pastor for St Mark’s, and our prayers were answered two-fold. Not only did we get a new
Pastor, but we also got a Deacon! I am overjoyed that we found the perfect team to lead us. A
lot of good things are already happening since their installation in October, from the St Mark’s
Play Group hosted by Deacon David to the Evening Adult Education hosted by Pastor Krista. I
can attest to the Evening Adult Education sessions with Pastor Krista have been very
informational and uplifting. One of the things I like is Deacon David at the Prayground in the
sanctuary teaching the sermon to the littles attending service. What an awesome way to
include them!

CASSIE BLICKEM
I am Cassie Blickem, and I am married to John Blickem. We have two children. Louie is 19 years
old and Russell is 16 years old, both confirmed at St. Mark’s. We’ve attended St. Mark’s for over
10 years. I lead the FDL class for the 4th and 5th graders on Wednesday nights and often
volunteer for the Hesed House PADS dinner.

GENA GERDIN
My name is Gena Gerdin, and I have been a member of St. Mark’s since 2021. I grew up in
Eau Claire, Wisconsin and we moved to Illinois 30 years ago. My husband Duane and I have
been together for 40 years, and my family includes two stepchildren and a wonderful group of
grandchildren. At St. Mark’s, I currently serve on the Outreach Committee and volunteer with
VBS, PADs dinners, and the LSSI Mobile Food Pantry, I accompanied our youth on their
week-long mission trip last summer and I’ve also taught Sunday School at St. Mark’s. Outside of
church, I am a CASA volunteer advocating for abused and neglected children in the court system,
and for the past 17 years I have led the weekly Harvesting Hope children’s program at Hesed
House homeless shelter. After retiring from a career in risk management, I now devote much of
my time to volunteer work. I bring to Council a strong commitment to service, outreach, and
thoughtful decision-making, along with a deep desire to support St. Mark’s mission and
community.

MATT GREISING
My name is Matt Greising. My family joined St. Mark's in 2001. My wife, Faith, and I have
three daughters and four grandchildren. On Church Council I coordinate the Property Team
and provide support for our online presence. In addition to Council responsibilities, I play with
the Glory Ringers handbell choir because I enjoy making music with an amazing team. I am also
a member of the group that bakes the bread we use for Communion because it is so gratifying
to be able to literally feed my church family.
St. Mark's is blessed with members who are caring and committed to sharing Christ's love with
each other and the community around us. I am blessed to be a member.

GREGG KOBLISKA
My name is Gregg Kobliska. I have been a member at St. Mark's since 2007. I live in Sugar
Grove with my wife Lorrie. We have 5 children and 9 grandchildren, most of whom live out of
state. When we first joined St. Mark's, Lorrie got involved with teaching FDL and I became
involved with the Property Team. After I retired, I worked at St. Mark's as the Facility Manager
until Lorrie retired in 2014. After that, I filled in during the summers for a number of years as
needed. Working in this capacity was a great way to get to know our facility, as well as many of
the parishioners at St. Mark's. I still am active on the Property Team and in 2024. I am very
aware of the need to serve our homebound and sick parishioners, which is especially true with
our aging congregation. Trying to help serve the needs of the church and our congregation
continues to be very personally fulfilling. I look forward to continuing to serve and contribute in
whatever way I am called to at St. Mark’s

MARY MANDEL
My name is Mary Mandel, and I became a member of St. Mark’s in 2009 when I was
pregnant with my oldest son. I am married to Craig and we have three boys, Aidan (15),
Ethan (13) and Ryan (10). The areas that I am most passionate about at St. Mark’s are the RIC
Team where we have made significant strides over the past several years in becoming a
much more outwardly welcoming congregation, and Youth and Family Ministry. I am
currently teaching confirmation but have taught Sunday School for many years and help with
VBS in the summer. I also occasionally play violin in worship, alone and with my family.
I believe that my gifts to council are my ability to listen to many sides and help mediate to a
resolution (as a teacher that is a necessary skill to have). I am a positive person, and I am also
very driven as well. I am used to working with many different people and am confident that
our council is moving in a solid direction to a common goal. St. Mark’s is in a good place right
now and is healing, and I am proud to be a part of that process as a part of church council.

MELVIN SMITH
Hello, my name is Melvin Smith. I have been a member of St. Mark’s for approximately
twenty-two years. My daughter Tatyanna was attending St. Mark’s preschool at the time, and
she told me that the Pastor from the church would come over with his guitar and sing with the
children. That is when I started attending St. Mark’s.
I have previously served two terms on council several years ago. I was mostly involved with
the hospitality teams for about ten years. I also taught confirmation classes as well.
I am currently a member of the Glory Ringers and a member of the AV team. I also serve on
the Worship and Arts committee, as well as the RIC committee. This past summer I worked
with a small group of people to update the St. Mark’s Constitution for submission to the
Chicago Metro Synod.
I look forward to giving my best effort and contributing all I can to the congregation of St.
Mark’s.

krista zimmerman
PASTOR
I have been at St. Mark’s since the beginning of March 2025. I have been a pastor for 15
years. I graduated from the Lutheran School of Theology at Chicago in 2010 with my Master
of Divinity. In 2006 I graduated from Houghton University in New York State with a Bachelor
of Arts in Communications. I grew up in Rochester, NY before coming to the Midwest. I’ve
been in and around the Chicago area for 20 years now and it feels like home. Especially since
my parents live in Naperville and my sister and her family live in DeKalb. I live right in the
middle- Sugar Grove. I love being a pastor but my favorite title is aunt! I am proud to serve a
congregation that is serious about living out our mission to "share Christ's abundant love
with each other and the world." In the past 10 months, I have enjoyed working with our
dedicated and faithful council. We have gotten a lot of work done to help the ministry of the
congregation run smoother including updating the constitution, re-working how we run our
council meetings, updating our personnel policy and much more. It’s really incredible how
much we have accomplished and I’m excited to work with our leadership in continuing to
live into our mission pillars in 2026! Click here to email Pastor Krista. Phone: 630-897-6891, ext. 101

David webb
Deacon
I am in my first year serving on St. Mark's Church Council as Deacon of Children Youth and Family.
I report on my day to day ministry which is at the intersection of worship, community engagement,
youth and family ministry, and the St. Mark's Staff. I collaborate most often with Pastor Krista, the
Children, Youth, and Family team, Worship and Arts team, Outreach Team, and the rest of the St.
Mark's staff. Beyond my call to serve as a rostered leader and my job description as a staff person,
I endeavor to serve St. Mark's and the Council by bringing thoughtful discernment, playful
creativity, and hand's on hardwork to our shared ministry. Originally from Chillicothe, Ohio, I first
moved to Chicago in 2008 to begin seminary at the Lutheran School of Theology at Chicago. Since
then I've taught Middle School at a Lutheran Elementary school on the South Side, served as the
Deacon of Faith Formation at St. Mark Lutheran in Mount Prospect, and The Deacon of Community
at Christ the King in Torrance, CA. I love Godly Play, contemplative prayer, being outside,
swimming, kayaking, and cooking with Christie, my wife of 13 years, Thomas (8), and Sam (5). Click here to email Deacon David. Phone: 630-897-6891, ext. 102
