About Us

RioMAC is a 501c3 non-profit organization created in 2004 as a means of assisting the Rio Grande Valley’s border mission ministries become increasingly self-sustaining. However, as that initial purpose ran its course, the focus of RioMAC expanded and transformed into a missional network across the Rio Grande Valley, Texas, and beyond.

Today, RioMAC is helping outreach efforts in the RGV for the at risk, the lost, the unchurched, and the fallen away by partnering with all 12 LCMS churches in the Rio Grande Valley, the Texas District, Concordia University-Texas, UpBring, Thrivent, through mission teams across the U.S. that serve in the RGV, and through mission-minded individuals like you!

Our hope and vision is “to inspire, develop, and equip: new and diverse leaders for new and innovative faith communities through powerful partnerships flowing across the RGV and beyond.” We are thankful for the exciting opportunities that God has given RioMAC to serve here in the Valley, and we cannot wait to see where He will lead us next!
