In this corner of the Southeast - where Tennessee, Georgia and Alabama meet - you’ll find Thrive Regional Partnership.

The nonprofit aims to cultivate what it calls “responsible and inspired growth” across 16 counties in the Greater Chattanooga region - in sectors from infrastructure, freight mobility and broadband to natural treasures, arts and culture.

Wednesday and Thursday, Thrive hosts its Tri-State Summit - presented by TVA - for leaders across industries, state lines and county lines at the Colonnade in Ringgold.

Bridgett Massengill is Thrive’s president and CEO.
