Pastors & Staff

Nick Seders

Lead  Pastor

My wife (Kelly) and I brought our family to Greeley First Assembly in May 2019, and felt at home right away! As Lead Pastor, I spend much of my time resourcing leaders within the congregation, meeting with congregants to provide biblical counsel, and preparing teaching material. Como viví en España durante más que 3 años, puedo servirte en español

Shane McClanahan

Associate Pastor

Aubrey and I are excited to serve families in Greeley after 10 years of experience in children's ministry, back home in Pennsylvania. We have four small kids that wake up everyday looking for the next adventure, so we love to explore and get to know new people.

Kelly Seders

Missions Coordinator

You can usually find me rearranging my house or trying out a new recipe! If I’m not homeschooling or planning events for the church, I love time spent around the around the table with friends and family. I have a passion for those who don’t feel like they have a seat to belong. My husband Nick and I (along with our three kids) have been honored to lead Greeley First the last 3 years.

Aubrey McClanahan

Kids Coordinator

I was invited to a VBS, and vividly remember giving my heart to Jesus even though at the time my family didn’t go to church. It is out of that turning point that my passion for kids was born. I desire to foster an environment where kids know they belong in the family of God and know that it's never too early to run into the arms of Jesus. I firmly believe that if Jesus takes root in the heart of a child, the fruit of that seed will continue to grow throughout their lives. As a mom of four, and a family photographer I love to get creative with engaging kids and ultimately families with the word of God to experience the power of God in a very real way. My husband Shane and I came to GFA with 10 years of kids ministry experience, and we love partnering with parents to help their kids live for Jesus in fun and real ways that will carry them through this moment I time that they were made for!

Nyle &  Alyssa Bernal

Youth Coordinators

My wife Alyssa and I have been married for 3 1/2 years and have a wonderful son named, Noah.
We both grew up in Greeley and enjoy serving our middle and high school students. We love spending time with family, friends, watching sports, and eating at wing shack!

Chris Burke

Office Manager

I’ve attended Greeley First for 40 years, and have loved serving as Office Manager for about 12 years. My amazing husband (Mark) and I have been married for 17 years, and together we have 6 children and 12 grandchildren. I love my family, camping, reading and doing crafts!

Vanessa Peterson

Office Manager 

I was born and raised in Greeley, Co. I met my husband Mike while away at college and we  have been married for 6 ½ years. We have a lively 3 y/o who attends Sonshine Preschool hosted here at GFA. My family and I have been a part of Greeley First for almost 5 years and I am  so excited to serve as an Office Administrator. I enjoy fishing with my husband, playtime with my daughter, and I love to watch movies in my free time.

Mel & Marcia Buxman

Prayer & Care Team Coordinators

I [Mel] was born and raised in Greeley, but attended Bible college in Missouri, where I met Marcia. After we married and I graduated, we returned to Greeley, making GFA our church home for eight years. In 1980 we moved to eastern Colorado where we raised our family, furthered our careers in agriculture and education, and stayed active in church ministries. We returned to Greeley in 2004, working in our chosen careers until retirement. We’re mostly homebodies, but we sure enjoy mountain get-aways and visiting our three children and six grandchildren around the country.

Kim Karlberg

Finance  Manager

I've been blessed to be with Greeley First for the past 11  years.  I own a small accounting practice, which has given me the freedom to be "home" and part of the "working" world. My husband (Tom) and I have been married for over 35 years and raised 3 children. We enjoyed raising kids, but grandparenting is even grander!

Cory Burough

Preschool Director

I have been with Sonshine preschool for 12 years and I just adore working with young children. I have attended GFA since 1991 along with my husband Mark who is apart of the deacon team. I serve our church body through the worship team.
I would love to have your child /children be apart of our amazing preschool. I look forward to meeting you!
