Meet our Leadership Team!

1 Thessalonians 1:8 is a powerful accolade of a church on mission.  “For not only has the word of the Lord sounded forth from you in Macedonia and in Achaia, but your faith in God has gone forth everywhere, so that we need not say anything.”  Our name is a reflection of the heart and passion of our leadership team.  Exēcheō, in the original Greek, comes from this passage, meaning “to sound forth”.  We are church guys.  We have sat where you sit, both in senior leadership staff roles and as lay leaders.  We are passionate about helping churches execute your vision and your mission towards more intentional kingdom impact through life transformation and community impact.  We believe strongly that every church, regardless of size, style, denomination, or location has a great opportunity to “sound forth” the power & love of Jesus.  Execheo exists to collaborate with you in this great mission.
