Pastors and Staff

Joel Miller | Pastor

I have been pastoring Columbus Mennonite Church since 2013.  My wife Abbie and I have three school age daughters who keep us on our feet, and backyard chickens who miraculously turn compost into tasty eggs.  As a pastor I have the honor of walking with people through the sacred events of life, and challenging us to recognize all of life as sacred.  I'm grateful for all the ways this congregation lives out its calling to be a community of grace and peace.    

I grew up on a farm in Bellefontaine, Ohio but have lived my adult life in urban areas.  Before moving to Columbus I pastored for seven years in Cincinnati, Ohio.  I am a graduate of Anabaptist Mennonite Biblical Seminary.  I have also lived for briefer stints in St. Louis; Philadelphia; Cairo, Egypt; and Atlanta.  All these places and the life they hold have shaped me.  I enjoy running, home improvement projects - of which there are many to do, and being amazed at trees.  

We would love to have you get to know our congregation. 


Mark Rupp | Pastor of Christian Formation

I joined the staff in 2014.  A large part of my role at CMC includes working with Christian Education and Small Group ministries, and I am honored to be able to walk with people and help them grow deeper in their understanding and practices of faith. 

I am a graduate of The Methodist Theological School in Ohio where I earned a Masters of Divinity with a specialization in Feminist and Womanist Studies.  I previously graduated from Bluffton University with a degree in music with a concentration in ministry.  Before beginning seminary, I also spent 3 years with Mennonite Voluntary Service volunteering full-time with the Boys and Girls Clubs of Hutchinson, Kansas.  When I am not being kept busy by both school and work, I like to spend my time reading, playing the piano, running, napping, and commuting around Columbus on bike.  There are few things I enjoy more than good conversation over a cup of tea, so feel free to contact me if you have questions or would just like to talk about life.



Gwen Reiser | Office Administrator

I began working at Columbus Mennonite over 10 years ago. I became the office administrator in July 2012. I am a graduate of Goshen College and spent my early career in medical labs as a technician. 

My husband, Peter, and I are the parents of 3 young adults, Hannah, Jacob, and Nathan and in-laws to Hannah's husband, David.

During my free time, I enjoy baking and gardening.

Miriam Halterman | Administrative Assistant 

I have attended Columbus Mennonite Church, formerly Neil Avenue Mennonite Church, since I moved to Columbus in 1987! I grew up on a farm in rural Ohio but have definitely become a city girl. I love what Columbus has to offer… the best zoo, great shows, lots of outdoor events, and space to garden!  I am married to Dan and I have two teenage college kids who provided my favorite job, stay-at-home mom. (Thanks Logan and Emma)! I went to Goshen College and OSU and have had numerous jobs at banks, Children Services, accounting position at an insurance company and most recently, being a Parent Consultant with Columbus City Schools at Indianola Informal before beginning to work part-time at CMC (again)!
