Elders love to walk alongside others in discipleship and prayer. At Crestview Church, elders are called by God to ‘bear up God’s people in their pain and weakness and celebrate their joys with them’ in being a Christlike example and support for others through actions and through words.’ Elders are also a primary support to the pastor. Elders are to engage in loving people well with love, compassion, and encouraging followers of Jesus to walk in the ways of Jesus.

We have five elders including the pastor, who seek to champion these things for our people: Gayle Yeo: council president, Julie Huffaker: council vice president, Roger Tinklenberg, Sydney Yapoujian and Pastor Mark.

To contact any of the elders, email us here at the Crestview office and indicate elder in the subject line.

I have been an elder at Crestview for the past 2 1/2 years.  I grew up in West Virginia in a Church of the Brethren church.  I met my husband, Vince, at a Conservative Baptist Church in Cambridge, Massachusetts when we were both in graduate school.  We adopted our oldest daughter and gave birth to twin daughters while in the Boston area, and then we moved to Colorado to be closer to Vince’s parents.  While here, we went on to adopt a son and give birth to another daughter.  Four of our children are young adults now, and our youngest is in middle school.  We found out about Crestview from a couple of friends of ours and have felt very welcomed and loved here.  Vince has served as a deacon also.  My current day job is homeschooling our youngest child, but I also like to garden, scuba dive, hang out with my family and friends, and lead the women’s weekly Bible study, Daybreak.

Roger Tinklenberg

Roger was raised in the Christian Reformed Church in Minnesota and attended Christian grade school, high school, and Dordt College (now University).  Dordt challenged Roger to think about what it meant to be a Christian and where he chose to live by faith.

Roger and Barb have been married over 45 years and have four adult children.  After earning a Master of Arts in Public Affairs from the University of Iowa, Roger worked for Iowa City, Saint Louis, MO, Eldora, IA, Federal Heights, CO, and Commerce City, CO.  Roger is currently the City Manager for Commerce City.

When he retires, Roger would like to again fish, hike, hunt, and woodwork.  But his current ways to relax and relieve stress is to lift weights, run, and write.  His writing production has dropped off in recent years because he has found that working on changing the work environment to be more Christ-like without using Christian imagery and language requires most of his creative energy.

Crestview has been Roger’s church home for over 13 years.

Sydney Yapoujian

Sydney Yapoujian has lived in Boulder for 13 years and helps her husband with their coffee business. She is a fine artist, musician, voice teacher and novelist. She has served Crestview as Worship Pastor in the past and is strongly committed to God’s word.

Gayle Yeo, President of Council

Newly retired with three grown children. Enjoying new opportunities through photography and traveling with my husband, Ray. I’m especially humbled to be serving the Crestview family during the most transformative season of the church. Praying, to God be the Glory!
