I serve as part-time Associate Pastor at St. Mark.  My primary responsibility is organizing a small-group Bible Study process. I assist in worship, preaching, hospital and shut in visits, and Bible Classes. More than anything else, I love leading adults in Bible Study, particularly in the Old Testament.

Born in Butte, Montana, I grew up in Belvidere, Illinois. I graduated from Concordia College, Milwaukee, Wisconsin, and Concordia Senior College in Ft. Wayne, Indiana.  I graduated from Concordia Seminary in St. Louis in 1976 with a degree in biblical languages and pastoral counseling. I vicared at Concordia in Denver, and ordained in 1977.  I served a dual parish in northern Wisconsin until 1979, and Good Shepherd in Fremont until retiring in 2015.

Barb and I have been married 38 years.  She is an exceptionally-gifted church musician, playing organ, piano, keyboard and guitar in both liturgical and contemporary styles. She studied organ performance at Iowa State University, and Midland University, and organ improvisation at Lutheran School of Theology in Chicago, under world-renowned composer, Dr. Paul Manz.

Barb and I have been blessed with Kristin and Jeremy, their spouses, and six grandchildren. The focus for my life and ministry is John 10:10, where Jesus says, “I came that they may have life, and may have it abundantly.”

I have been our Director of Music Ministries since 1997. I am currently tasked with music preparation for our 8:00 AM and 5:30 PM worship services. I help plan the service outlines in consultation with the pastors. Then I gather the music and the musical forces for these services. I direct the Adult Choir (for our 8:00 service) and occasionally round up a men's choir, handbell choir or various groups of instrumentalists or vocalists to enrich our worship. I play organ and piano for many of our services. I work with our other organist, Glenda Bock and our Children’s Choir director Vivian Kesar as they prepare music for worship. I often help out with VBS music and Preschool music. You'll see my monthly updates on music ministry in our Messenger newsletter.

I am married to Vivian and we have 4 children, Natalie, Ethan, Avery and Jonah. Vivian and I both come from Michigan (although from opposite sides of the state) and have family still there. We both attended Concordia College in Ann Arbor Michigan. I taught high school choirs and religion in Milwaukee and Queens, New York before coming to Omaha. My theme verse for ministry is Psalm 119:54 Your decrees are the theme of my song, wherever I lodge.

I pray that I may be a blessing to you and your family as well.
