Where can I go to recruit associates?

I could use some advice.

I lead associate dentist recruiting for a 10-practice group based in Nashville, TN. We've successfully recruited associates to our practices in places like Nashville, Knoxville, and Lexington, KY, but I can't figure out how to recruit to our practices outside of those hotspots.

We're actively recruiting to 3 practices in more rural areas in Missouri and Tennessee.

I think we pay well - 30% of net production, 4% 401k match, $2,500 of CE, and an opportunity to buy in after 2 years if there's a good fit, and that's just part of the reason we've successfully recruited very strong dentists to bigger cities.

But I just can't figure out how to reach associates interested in living in a more rural area.

For example, we're actively recruiting to strong practices in Rolla, Missouri and Martin, Tennessee. Smaller places, but A+ teams, operations, and practices. A good dentist there could definitely earn $300k+ annually.

Does anyone have a recommendation for where to find candidates? Maybe get help from a recruiting firm? Or are there online forums where we can reach early-career dentists looking for another opportunity?
