He joined us as our Pastor and Teacher in August of 2010. He holds a Bachelor of Arts degree in General Studies (Pre-Ministry) from the University of Evansville, Indiana, and a Master of Divinity degree from Garrett-Evangelical Theological Seminary.

Please enjoy Pastor Dave’s sermon blog, Post Pastoral. In another blog entitled, From the Tower Room, he reflects on the life and history of First Church.

Pastor Dave contributes occasionally two other weblog series on this website. One is Musings and Meditations and offers his spiritual perspective on a number of matters. The other, A Journey for Renewal, presents Pastor Dave’s thoughts and reflections about his sabbatical in West Africa and other locations significant to African American history and culture, June – August 2017.

Support Staff

Debbie Tolstoi, Office Administrator, came to First Congregational Church at the end of January, 2017. She has worked in the past as the administrative assistant at Christ Church, United Church of Christ, in Maplewood. For over 20 years she has run her own web design and marketing business, Tolstoi Designs. Not inclined to work only in an environment by herself, even though her terrier Buddy has been by her side, Debbie decided to apply for our Office Administrator position when she saw it posted in the Webster-Kirkwood Times.

Debbie is a graduate of Parkway Central High School, studied Studio Art at Maryville College (which the University was, then), and graduated from Webster University with a degree in Management and an emphasis in Marketing, receiving departmental honors.

She lives in St. Louis with Buddy “the bad thing” (at least to rabbits, who rarely survive an excursion in her back yard). She is a passionate gardener.

Chip Isringhaus, Facility Manager, has been with the First Congregational Church since 2002. If you need to learn the ins and outs of the inner workings of our physical plant, Chip is your man. His education and experience include an HVAC Certification from Ranken Tech, which he received as part of his service to the church when our new heating and cooling system was installed.

He has one son, Calvin, and enjoys restoring classic Chevrolet Chevelles.


Darrell Lakies, Custodian, is very often the first person you meet when you arrive at the First Congregational Church. He extends our extravagant welcome to any and all who enter.

With the church since 2010, Darrell once worked in a similar capacity with Chrysler at their Valley Park plant prior to its closing. He also served with the U.S. Navy during the 1970s.

Darrell keeps our buildings spotless and well-maintained with great competency and exudes an infectious joy and positive attitude.

Darrell is the husband of Kelly. In his spare time he enjoys his pool or camping.
