Pastor David Siczko
Senior Pastor


Rev. David A. Siczko has been a Pastor for over 37 yrs.  He is known as “Pastor Dave.”  His personal desire is to serve the Lord as long as he is able …by serving God’s people.  His late father, Rev. Alexander I. Siczko who was the Pastor of the Good Shepherd Bible Church in Chicago for over 57 years used to say “I’d rather burn out then rust out!”  When he was 80 yrs old he asked his son if he wanted to be the Senior Pastor and Pastor Dave replied “No Dad! Just keep on preaching as long as you make sense! I will do all of the running around.” The Lord graciously took him home in his sleep, still sharp minded and filled with the Spirit of God almost 86 yrs old.

Pastor Dave left the business world in late 1975 and started in the ministry in January of 1976, as part time Youth Pastor at Good Shepherd under his father. His educational background is decidedly not theological.  He attended Northeastern Illinois University from 1967 to 1971, graduating with a B.A. in Economics.  He then attended the University of Chicago Business School from 1972 to 1974, graduating with an M.B.A. in Finance and the goals he had set for his life, were making him miserable.  At a corporate gathering, he called his father and told him that he had decided to follow in his footsteps in the ministry, as his grandfather prayed for just prior to his death many years before when Pastor Dave was about 10 years old.  Pastor David told his father “Everything I have wanted money for, I already have.”

In 1977, Pastor Dave was accepted into a four year internship program with the Assemblies of God leading to the license to preach in two years and full-ordination at the end of the fourth year.  During this time he took Bible courses at the Assemblies of God, Berean Correspondence School to fulfill their requirements.

Pastor Dave taught Economics at Northeastern Illinois University both part time and full time until 1991.  During this time he was accepted into the Economics PhD program at Northern Illinois University.  He pursued his degree for two years part-time but chose to give it up, due to his responsibilities at Good Shepherd.  

In the summer of 1979 Pastor Dave became an Assistant Pastor at Good Shepherd upon receiving his license to preach and later in 1981 he became an Associate Pastor just after his formal ordination by the Illinois District of the Assemblies of God.

He not only worked as an Associate Pastor side by side with his father, but he was also as the Director and Principal of the perish school, Chicago Christian Academy from 1979 until the ownership of the school was transferred to the Evangel Assemblies of God on Diversey Ave. in 1991. He became the Senior Pastor upon his father’s passing in November, 1996.

Good Shepherd began with Rev. Alexander on 745 N. Paulina, from moved from1956-1958.  In 1958, the church moved to 6435 W. Belmont. In 2002 the church moved to Lake Zurich, and then on to a brand new multipurpose Worship Center in Lake Zurich in June of 2003.  

When the Church of the Full Gospel merged with Good Shepherd Bible Church, he became the Pastor of the new Church, Good Shepherd Christian Assembly in 2006.

In October of 2011, we were given a former Italian Pentecostal church by the graciousness of the Congregation. After extensive renovation, Good Shepherd Christian Assembly Gospel Outreach opened with a Resurrection Service on October 28, 2012. 

Pastor Dave and his wife Linda live in Round Lake Beach, IL.

Linda Siczko
Director of Children’s Christian Education & Ministry
Missions Ministry Board Member

Linda Siczko
Born in Chicago, Linda is the daughter of Pentecostal parents, has one older brother, Stephen.  Grew up in store front churches and then family spent several years at Calvary De
af Assembly assisting Pastor Couch, where she and her brother learned Signed Exact English (Sign Language).  At 16 had a Sunday School class for 2-3 year olds at Century Assembly of God in Mundelein. She graduated from CLC in 1985 as a Practical/Vocational Nurse, worked in Geriatric Nursing for several years and Alzheimer Administration.
Currently works as a Licensed Coder/Auditor /Educator in Medical Records as a Government Employee.

She and the Pastor were married in June of 2009.  In addition to each having one attendant standing up with them, there were 10 kids in their wedding ranging in age from 18 months to 15,  they were the children of Sunday School and of close friends.   God, family, the children and friends; that was the theme of their wedding.
She and the Pastor have a heart for Missions, especially kids and teens.  “The kids and teens come first.  We grownups are older, a little or a lot more seasoned and have had our day and our foundation set, but we need to focus and make sure the younger ones get fed, spiritually and physically, and equip them to pass the torch to.
The teens are at points where they need direction in their life, some are at crossroads with life making decisions.  Too many kids and teens on the streets with nothing to do, thinking no one cares, making wrong choices. We just want them to know that we care and how much they mean to us and especially to God. The children are the heart of the church. It’s very different today compared to when I was growing up in the church. Most of the kids do not come every Sunday with a two parent nuclear family.   They come with one parent, grand- parents or alone on the bus picked up by our transportation ministry. “
She and the Pastor have a party at their home every year for the kids and teens between Christmas and New Years and other times throughout the year.
“I would like to eventually see all the kids and teens get involved in praise and worship, and/or behind the scenes at GSCA, I do not want to discourage that, and that it’s not just for grownups.  They are interested in different instruments, so we will encourage them in the areas they feel like they want to do. I would like to encourage the kids here in our church to be a part of Missions outreach to other kids in this country and around the world who are hurting.”
Pastor and I are so proud of the kids in our two churches; we have a small but great group of kids. I believe I am one of five of their chief champions besides Pastor Dave and the teachers.   I admire their energy and enthusiasm, and tender heart.  We love to hear them come flying in like gang busters! These kids are all very close to each other and dear to me and the Pastor.”
Kathleen McHugh-Steiner
Music Director/Worship Leader

Kathleen’s ministry is devoted to bringing God’s people to a place of worship.
At the age of 5, Kathleen felt the Lord call her into the music ministry. She began singing and playing the organ in church. She knew this is what she would do for the rest of her life. From there, she went on to play the piano, guitar,and upright bass.

Kathleen has performed with many Christian, Bluegrass and Country artists  such as Sandi Patti, Steven Curtis Chapman, Ron Kenoly, The Isaacs, Doyle Lawson, and HEE HAW cast members to name a few. Kathleen loves Gospel music and loves the inspiration and ideas that she gets from her favorite artists Fred Hammond, Marvin Sapp and Donnie Mcclurkin.

Kathleen says "I really love playing Gospel and Contemporary music but I will never forget the simple songs that I grew up with in church like 'Wonderful, Wonderful Jesus is to me'. It's not always about having the most contemporary songs during the worship service. It's about being in the presence of God. If you come to our services, it doesn't matter if we have 20 people or 100 people, God is working on hearts. I believe in blended worship and it thrills my heart when the worship team has no clue that the "new song" that they are learning is really from 1965 with contemporary chord progression (LOL)! I love when we open the alter before we even start the sermon. I promise you will feel like you are in an on fire revival service and  will be blessed!

Kathleen and her husband Bobby along with their 3 children Cody, Logan and Heavenleigh and 4 guinea pigs live in Chicago. Kathleen and Bobby enjoy home schooling their children through a Bible based curriculum that challenges their children to develop a relationship with Jesus Christ, incorporating the character traits of the Lord.
