Reverend Mike Knauff

Pastor Mike Knauff has served as a Lutheran pastor for over thirty years in various size congregations in various settings across the U.S.A.: Frewsburg, New York; Fairfax, Virginia; Castle Rock, Colorado; Greenford, Ohio and now here in Idaho Falls, Idaho. Mike married his college sweetheart, Deborah and they have three grown boys: Adam, Stephen, and Caleb, who have blessed them with wonderful daughter-in-laws and one granddaughter. In his free time Mike likes to be with family and play with his elderly pound puppies (Roo an Australian shepherd mix, Pippin a Bichon Frise mix). Some of his other interests include solving sudokus, camping, hiking, fly fishing, playing guitar, basketball, cards, or board games. His greatest thrill is helping people get closer to God in their faith walk.

Church Administrator

Heide Larsen

My name is Heide Larsen. I was born and raised in Redford Township, Michigan, and attended college in Detroit to become a Graphic artist. At the age of 25 I took a trip to Snowmass, Colorado, and discovered I needed to live in the mountains. I moved to Snowmass the following year. Four years later I moved to Idaho Falls. I have two daughters, Hailey and Taylor. Hailey is in a Masters/PhD program for Clinical Psychology at Seattle Pacific University and is married to Jesse Caudle. Taylor lives in Oregon with her husband Dan and is an Athletic Trainer at Portland State. We have been members of First Lutheran since 1997. Both girls made their first communion and were confirmed at First Lutheran. 

In 2019, I married my best friend Dennis. In our spare time we enjoy downhill and x-country skiing, swimming, biking, hiking, and camping. I also enjoy gardening and reading. 

In October of 2013, I was fortunate to have First Lutheran hire me for the position of Church Administrator. It has been such a blessing to work with and for so many wonderful people. Part of my responsibilities is to take care of the Building and the Property and attend all council meetings. So, when the Property Liaison seat became available, it seemed natural that I should fill that spot also. 

I look forward to many more years at First Lutheran and the opportunity to work with all of the wonderful members here.


Greg Stultz

Let me introduce myself. I am Greg Stultz the current Bookkeeper for FELC.  

My background in the accounting field comes from being the Business Manager for Morrison Knudsen, what used to be a worldwide construction firm headquartered in Boise, Id. And yes, I was able to go around the world with them on numerous construction jobs. What a great way to see the world. When we moved here in 1993 I worked for MK at the site as an auditor. We decided to stay put and I continued to work for the various contractors . I retired after working at the INL for 18 years.  

For fun for the past 20 years I have been running up and down the football field as a Football Official and have been involved in Babe Ruth and American Legion Baseball. I enjoy working with the kids participating in sports.
