Worship Director

Nick joined his first worship team in 2006 which is when the Lord began creating a deep passion in him for pure, intimate worship and leading others into an atmosphere where they can experience the power and presence of God. Nick loves cultivating musicians, singers, songwriters, and worship leaders on a natural and spiritual level. Nick attended Victory Bible College in Tulsa, Oklahoma and has served in both student and worship ministry within the local church.

As the Worship Director at Grace Church, Nick’s goal is to provide a place where the Lord can minister to each person that attends our services in a tangible, authentic, and impactful way.

One of Nick's many passions is missions and he has been on several trips ministering in the states and overseas, seeing God’s power displayed on every trip. His hobbies include hunting, fishing, and collecting every kind of video game. 

Nick is engaged to the lovely Charity and is insanely excited to marry her in 2018! Charity is actively involved in the Worship Team and is the worship leader in our student ministry.

Audria Bobbitt

Kid's Pastor

Pastor Audria and her husband, Aaron, were married in 1996 and love serving in the ministry together. They have been members of Grace Church since 2004 and have two daughters, Hailey and Emma. The girls have grown up at Grace Church and help out with the children’s ministry where they can.

In 2008, Pastor Audria began assisting in the nursery at Grace Church. Soon after, she and her husband started teaching in the four year old preschool class.  In the summer of 2011, she came on staff as the Nursery and Preschool Coordinator.

Grant Jacobs

Student + Small groups pastor

Cassie Jacobs

Creative Director

Pastor Grant and Cassie believe there are only a couple important things in life. And while enjoying the outdoors and drinking black coffee is admirable, serving the local church tops the list. Married in 2007 and finding Grace Church that same year, they have served in multiple areas of the church.

Pastor Grant flew in corporate aviation for almost 10 years and was just getting the hang of it when he transitioned to full time ministry. He enjoys never going inside, reading and spending time with his wife and friends. Although Pastor Grant isn't known for his multitasking skills he oversees both the student ministry and Small Groups. His passion for [United] Students is that these formative years become the foundation for a lifelong love of Christ and His Church. And Pastor Grant believes life is more fun and fulfilling when done with others so you are cheating yourself if you aren't apart of a Small Group.

Cassie followed the typical creative career track by working as a barista in multiple locally owned coffee shops and coloring her hair before Katy Perry made it cool. She loves to laugh with people and when she has a few spare hours she'll nap or binge watch Gilmore Girls. If you’re not entirely sure what a Creative Director does, neither are we. However, Cassie’s primary responsibility is planning our services and she oversees our website and social media as well as our worship, production, visual design, events, and coffee shop teams. Cassie is passionate about creating environments where people feel at home, have fun, and find it easy to meet God.

Both Pastor Grant and Cassie were homeschooled so speak slowly and use small words around them.
