MEET THE GREENTREE TEAM

Justin Cook

TEACHING MINISTER

It's hard to believe my family has been a part of Greentree for over 20 years now. My wife and I moved here from Illinois back in 2000 and Greentree has truly become our church family. I have worked in a number of different roles at Greentree over the years. I worked with the youth for over a decade, transitioned into working with adults in connections ministry, and now I am currently serving as one of the teaching ministers.

I met my amazing wife Jana back in Bible college and we have been a team in ministry and married since 1998. The Lord has blessed us with three incredible kids: Emma, Gaby, and Dexter. I love running, basketball, baseball, soccer, disc golf, and more recently pickleball. I am a big St. Louis Cardinals fan, a University of Illinois fighting Illini fan, and a Chicago Bears and Bulls fan. I also enjoy reading, fishing, coffee, photography, and spending time with my children.

Chris Foster

TEACHING MINISTER

I was born and raised in Peoria, IL and came to Rolla with my wife Dorothy and my 1-year old son Danny in 2004. Since then we have added Luke (born in 2004) and Joey (born in 2007). Our whole family loves being a part of the community here in Rolla and at Greentree Christian Church. I have been very blessed to be a part of this church family and to be a part of the work God has done here. In addition to teaching and preaching, I really enjoy playing basketball with the guys here in town and playing all sorts of games with my 3 sons.

Ben Harris

YOUTH MINISTER

I have had the unique opportunity to be a part of our church for my entire life. It is such a joy to be able to work in my home church! I started working at Greentree in 2008 as a youth intern, and in 2012, I was blessed with the opportunity to be the youth minister. I love spending time with Jr. High and High School students, and teaching them about God.

I have been married to my amazing wife Shandi since 2009. She is a campus minister with CCF at MST. We have two daughters, Darci and Harli. My favorite things to do are spending time with my family and hanging out with our students. I am a huge STL Cardinals fan & I enjoy collecting baseball memorabilia and autographs.

Brandon Crosser

ASSOCIATE YOUTH MINISTER

My journey with Greentree started as an intern in the summer of 2017. What was purposed to be a one time commitment turned into a full-time position as the Associate Youth Minister, after I graduated from Ozark Christian College in may of 2018. At OCC, I received a Bachelor of Arts in Christian Ministry, emphasizing in Student Ministry in an effort to support my passion of raising up the next generation of church leaders. I have followed Christ ever since I accepted him during a week of CIY the summer after my freshman year of high school. Since then, God has led me from Tulsa, to 5 years of Bible College, and finally to Greentree where I want to continue to faithfully and sacrificially serving the Lord and the community of Rolla.

Brenden Pristach

ADULT DISCIPLESHIP MINISTER

I grew up in Herscher, IL (Smalltown USA at its best) and moved to Rolla with my wife Savanna in May of 2019. I love basketball and football, video games, and certain board games. I also root for the University of Michigan (Go Blue!) in all sports because I’m partial to winning. 

My wife and I are incredibly excited to be a part of the community here at Greentree and in Rolla and we were drawn here because of the love we felt from the staff and congregation from the first time we visited. I am passionate about walking alongside others in their faith and working with people as we chase after God together. I look forward to the years of ministry ahead!

Phillip Shull

WORSHIP MINISTER

I started serving the Lord through worship on drums and vocals at the age of 10 and have been involved in church music ever since. In 2006 I graduated from Northwest Missouri State University with a degree in Music Education to pursue a passion for teaching others. That year I also married my amazing wife, Diann, and since then God has blessed us with 8 amazing children who love the Lord.

In 2021 God fulfilled a musical desire of my heart by providing a full-time position as the Worship Minister at Greentree Christian Church. Team Shull loves the life we have found in the Rolla area and we feel like we are home, amongst family at Greentree. We are honored that God has seen to it to bless our socks off with a dream job that exceeds my prayers and wildest dreams. God’s timing is the best and we are so excited to be here with the Greentree family!

Cassie Jamison

CHILDREN'S MINISTER

Hey there! I’m Cassie, Greentree’s Director of Children’s Ministries. I started this position at the beginning of the June 2022. I’ve been a middle school/junior high math teacher for the past 7 years. However, this position is not brand new to me as I’ve been a member of Greentree since my family moved to Rolla in 1998. My mom, Charla, was the children’s minister for 11+ years when I was in high school, so I helped out with everything under the sun.

My husband Lane and I got married right here at Greentree in 2018 and had our son, Cade, in 2021. He has gone through some health issues being born premature, but he has grown into a spunky little guy with such a sweet personality.

When I’m not at church, you can find me spending time with my family, binge watching all the Disney movies, and hanging out with members of our church small group. I also love crafting, reading, playing board games, and all things glitter! Greentree is my home and I am so happy to be part of this team!

Scott Robinson

MISSIONS MINISTER

I love reaching out with the love of Christ to the world, and my job as the Minister of Missions and Outreach has enabled me to do just that since 2009!  I enjoy reaching out to the international students at MS&T, helping them understand the American culture and learning common English so friendships can be made while they are in the U.S.  I also look forward to leading our mission trips, visiting each of our partners who reach the world with the Good News of Jesus Christ, and seeing how the Gospel is lived out among the many different cultures. 

 

My wife and I married in 1997 and we were blessed with our first son, Nat, in 2006, and then our twins, Sam and Zac, in 2007.  We served as missionaries with Pioneer Bible Translators in Papua New Guinea between 2003-2008.   I enjoy playing almost all sports, but especially racquetball and volleyball.  My wife and I play board games and card games for fun.  I enjoy listening to all kinds of music and playing music on my bass.

Charla Jamison

BUSINESS ADMINISTRATION MINISTER

In 1998, our young family moved to Rolla from the KC area. We connected with the people at Greentree immediately. In 2004, I started working full-time for Greentree as the Director of Children’s Ministries. In 2015, after 11 years with the children’s ministry, a unique need arose. God showed me a new way to serve! Details are my thing and administration for the church suits me well.

Jeremy and I married in 1992. He is a school counselor at Rolla Junior High. We have two children. Our daughter Cassie is Greentree's Director of Children's Ministries and lives in Rolla with her husband, Lane and grandson Cade. Our son Jacob is a musician and lives and works in nearby Springfield, MO.  Our family loves books, movies, music, laughter, friends, our dog family, our toes in the water, the KC Chiefs and spending time together. My mantra of the past several years has been "embrace the stage." Because our lives can be so full and such a blur, it's important to experience and enjoy the stage I'm in. My new stage, and I'm totally embracing it: Grandma Charlie.

Justin Renaud

VISUAL ARTS DIRECTOR

I started working at Greentree in 2010 and have grown to really love my job. I have the opportunity to capture memories and moments through video and it really has become one of my biggest passions in life. Seeing the reactions people have to the content we produce here really make this job incredible. It is fun to be a part of a growing/thriving church family.

I am so blessed to have my incredible wife, Becca. We have 4 great kids (Hayden, Keaton, Khushi, and London) who are a joy to watch grow up. My favorite things to do (besides spending time with my family) include disc golf, tennis, watch any sport, watch anything sci-fi or superhero, pickleball, and shooting video of all kinds.

Megan Clay

Part Time children's minister (Pre-k emphasis)

I grew up at Greentree and spent the majority of my teen years serving and babysitting with the Treehouse Kids! I joined the staff in 2013 as an intern, came back part-time in 2014, and stuck around full-time in 2015. In 2015, I married Bradley and over the years our family has grown. I'm back to working part-time with the early childhood ministry- hanging out with preschoolers and toddlers is my favorite!

Outside of life at Greentree, our family loves to be outside digging in the dirt, exploring new states with our kids, and playing board games.

I'm so thankful for the community I have because of Greentree.

Rachel Allison

GREENTREE LEARNING & CHILDCARE CENTER DIRECTOR

Hi there! My name is Rachel Allison and I am happy to serve as the Director of the Greentree Learning and Childcare Center. I am passionate about early childhood education and teaching kids about Jesus! My family, including my husband Jim and three kids, Bailey, Christopher, and Emma have lived in Rolla for the past 15 years. In my free time, I enjoy spending time with family, reading and baking.

Lee Nightingale

Women's ministry director

My beloved husband and I moved to Rolla in 2012 and immediately began attending Greentree Christian Church. We married in 1982 and have two adult children. I helped lead a cancer support ministry for (mostly) women for many years and I also volunteered as a Court Appointed Special Advocate (CASA) for several years in support of foster children in Phelps County. My professional background is as a leader with the US Forest Service from which I retired after 35 years of service in 2011, where I was last responsible for 15 National Forests in the midwest and northeastern United States. I have extensive experience in leadership, human resources, employee development, and natural resources. My undergraduate degree is from Kansas University (Rock Chalk Jayhawk!) and I am a Harvard Fellow. I was appointed  the first Chair of the national Learning Council and I served as an executive coach for high potentials in the >30,000 employees agency for years.

Jesus is Savior! Baptized as a little girl, I taught Sunday school and have led Bible studies for many years. As the Director of Women’s Ministries at Greentree, I am creating a learning environment, “Rooted in the Word”, and focused on the love of Jesus! I will do all I can with God’s help to encourage Greentree women. God bless you all.

Savanna Pristach

PART TIME CHILDREN'S MINISTER (special needs EMPHASIS)

I am originally from a small town called Herscher, IL and moved to Rolla with my husband Brenden in 2019. I joined the Greentree staff in February of 2020 and am so thankful to be part of a staff that loves others so well. My husband and I have since added a little boy to our family and we are so excited to be able to raise him in this community. My favorite things to do are to spend time with my husband, son, and play board games with friends!
