Pastor Lonnie Shields – Worship Director

Pastor Lonnie and his wife, Diane, both graduated from Oral Roberts University (they got married the evening of Graduation Day). They founded New Life Christian Fellowship on the northeast side of Grand Rapids and pastored there for many years until a woman ran a red light and hit them almost head-on at about 65 MPH in 2012. The serious injuries they both sustained forced Pastor Lonnie to retire from pastoring New Life. Diane has suffered through nineteen surgeries since the wreck and deals with chronic pain.

Lonnie’s father fostered his love for music, teaching him to play the mandolin in church at the age of three, and encouraging him to take up other instruments as he grew. Praise and Worship has always been a strong focus of his personal life and ministry, especially when he came to understand that God “inhabits the praises” of His people (Ps. 22:3 KJV).

Sara Barnaby – Administrator

Sara has been a member of Discovery for over twenty years. She has served in many ministry positions, including Elder. Most recently she has been hired to serve as the administrative and communication link within the church. Through emails, text, bulletin announcements, daily prayer requests, ministry leader reports, setting schedules and a host of other ways, Sara serves the church family by enhancing strong communication lines.

This position also includes church office hours, Tuesday and Thursday from 9:00 AM – 12:00 PM.

Sara is married with four children. She is also a licensed professional counselor.

Ted Jarmon – Facilities

Ted has been a member of Discovery Church for over twelve years. He has served in various ministry positions over the years and has mentored and continues to mentor where needed.

Ted has been Discovery’s custodian for over 10 years. He is also employed as a supervisor for a manufacturing company (plastic injection molding) for the last 18 years.

Ted’s free time is spent mostly studying the Word and watching anything sports related! He has two children, Abryanna and Ted Jr.

Ahna Ziegler – Digital Content Manager

Ahna grew up with Discovery Church, toddling around in the church’s infancy and singing on praise team as soon as she could. During college, she began designing graphics and creating videos while serving on Discovery’s worship planning team.

After working in marketing at Eerdmans Publishing for 6 years and then running her own freelance business, now she splits time between managing Discovery’s digital presence and taking care of her two children.

Ahna spends her time knitting, reading, and watching Star Trek, and shares a love of board games and local cuisine with her husband Dan.
