Warren embraced God’s love in Christ in his early 20’s, about the time he met his beautiful wife, Cathy. They both grew up in church, but God brought them to himself and to each other in faith and marriage, some 34 years ago. After working for six years in education, Warren returned to seminary to complete his Masters of Divinity at Columbia International University. God called him to Apex in 1997 to plant Ambassador, where he’s been ever since, serving as pastor of the people of Ambassador for over 25 years. Warren loves to see people’s lives changed by the love of Christ and power of God’s Spirit through his Word, and to help people walk through the pressures and struggles of life in the strength and joy Christ gives. Warren and Cathy have four sons, who are now grown and married, and enjoy being grandparents. Warren is an avid sportsman, with a love for boating and baseball, hunting and fishing, hiking and biking, and cooking on the grill and enjoying a good meal with family and friends.

He is an accomplished singer/songwriter and leads the congregation in worship and outreach at Ambassador. Greg’s theological training is from Reformed Theological Seminary and Birmingham Theological Seminary. He is an ordained Pastor in the Associate Reformed Presbyterian Church and was assessed and approved as a Church Planter by Outreach North America.

Randy and his wife Julie came to Ambassador in June of 2021 from California where Randy taught and pastored for 18 years. From the first Sunday visit, they fell in love with our church family. Since November 2022, Randy has counted it an honor to serve on staff as the Executive Director. He feels strongly that church ministries need administrative oversight, and trusts that his four decades of ministry has given him the experiences to help his church family in this way. While Randy is a native Californian and a survivor of three major California earthquakes, Julie is totally mid-western, St. Louis born and raised, a die-hard Cardinals fan, and still a baseball card collector! Besides his official duties, he and Julie are pledged servants of the rising generation. They want to see the next generation of families and youth become all that God intends for them to be!

Director of Youth and Children’s Ministry

Rachel Kennedy

Rachel was born and raised in the Cary/Apex area and has been on staff at Ambassador since 2016. She attended Wingate University and graduated with a degree in Human Services. Her passion for teaching youth and children about Jesus and watching them grow in their faith started in high school when she began teaching a three-year-old Sunday School class and she has never stopped! Rachel is amazingly creative and loves planning fun events (VBS is her favorite time of the year!) and she pursues meaningful connections with each child. She also embraces her role to support and equip parents as they raise up a new generation of followers of Jesus. When Rachel isn’t working, she enjoys baking, crafting and all things coffee!
