I recently came across this organization, The Irish Gift, based near Nashville in Franklin, TN that says it’s goal is “to promote, revive, preserve and celebrate the traditional Irish culture in Tennessee.” They have classes for Sean Nós singing & dancing, fiddle & flute and most importantly for me, Gaeilge.
Here’s their website: http://theirishgift.org/
I’m planning to move down to that area in the next year or so and I can’t tell you how happy I am to know I can continue my studies down there. I know you’re about 3 hours away but seeing as you’re both based in TN, they might be a great resource for expanding your organization’s reach and ultimately building a greater Irish language community in Tennesse. Hope this helps!
